All About Vision

Lens Options for Eyeglasses

If you thought the trickiest part of choosing a new pair of glasses was the frame selection, think again. You should be putting just as much thought and consideration into the lenses that you select for your new specs.

Here’s why:
The quality and type of lenses in your eyeglasses will not only correct your visual acuity, but they will allow you to continue to see your best through various conditions. Whether it is keeping the lenses free from scratches, fog, glare or UV rays, or making them stronger or more attractive, your eyeglass lenses can help to keep your eyes safe and comfortable wherever the day (or night) takes you.

Lens Coatings

Here are a variety of coatings that you can apply to your lenses to maintain optimal vision and comfort and to protect your lenses and your eyes.

Anti-reflective/Anti-glare Coatings

Anti-reflective (AR) also known as anti-glare coatings help reduce the reflections and glare on your lenses, improving your vision and comfort in high-glare environments, and the look of your glasses as well (you can see your eyes clearly without a reflection on the front of the lens). Reflections from the sun, television and computer screens and bright lights (especially when driving at night) can cause eye strain, headaches and difficulty seeing. AR coatings and lenses can reduce this effect, improving your vision quality and comfort in these circumstances.

Scratch Resistant Coatings

Scratches not only affect the smooth look of the surface of your glasses but they can disrupt your vision. A scratch-resistant coating adds an extra layer of protection on the surface of the lens to significantly reduce scratching. This coating is particularly great for kids who may tend to be a little more rough with their eyewear.

Ultraviolet Coatings

Ultraviolet (UV) coatings protect your eyes from harmful UV rays from the sun. This coating can turn standard lenses into UV blocking lenses that can block 100% of the UV light from entering your eyes. UV is linked to the development of a number of eye diseases such as cataracts, macular degeneration and retinal damage.

Anti-fog Coatings

Particularly if you live in a cold climate, you may have experienced walking indoors from the cold and having your glasses lenses fog up completely. This can take a few minutes to resolve and can be dangerous if you are driving or need to see clearly. Anti-fog coatings will eliminate this effect, creating a smooth transition from cold to hot environments.

Lens Options

You may want to go with an upgraded lens to improve the look, strength or functionality of your glasses.

High Index Lenses

High index lenses have a higher refractive index which means they reflect more light than standard prescription lenses. What this means for you, the consumer, is that they can be made thinner and lighter than traditional lenses. High index lenses are particularly popular with those that need a high prescription as they are able to avoid thick lenses, adding comfort and a smoother look, but a higher price tag.

Trivex or Polycarbonate Lenses

Trivex or polycarbonate lenses are impact resistant lenses – a fantastic choice for sports and safety eyewear as well as standard sunglasses and eyeglasses for active types or kids. These lenses also offer full UV protection and are lightweight for optimal comfort.

Polychromatic Lenses

Polychromatic lenses are made with special technology that turns them into sunglasses when exposed to sunlight. The lenses darken automatically when you go outside and return to normal when you go back indoors. Polychromatic lenses can come in a number of tint colors and are great when you need prescription sunglasses but don’t want to carry around or pay for another pair.

Aspheric Lenses

Aspheric lenses use advanced technology to create a slimmer, flatter and lighter lens than standard prescription lenses. While aspheric lenses can improve the appearance of any prescription lens, they are especially beneficial for those who are farsighted since those lenses tend to bulge out in the middle.

So the next time you are in the market for new eyeglasses, speak to your optometrist or optician about the best lens choices for your eyes, your vision and your lifestyle.

Pediatric Developmental Eye Care

Pediatric Eye Doctors in Central New Jersey

Even if your child has “20/20” eyesight he may be experiencing vision problems. These problems may be causing learning problems and substandard educational results. A child's visual acuity ( how well s/he can see the wall chart) is an essential aspect of good vision but there are other factors which may prove more important. You may already be aware that a nearsighted child has little trouble reading or that good grades in school can be acquired even if much of the teacher's board cannot be seen by the student.

Considerations Related to Eyesight and Learning

Eye movement skills: Do your child's eyes move across the page in a book smoothly and accurately?

Eye focusing abilities: Does your child change focus from near to far and back again -between reading text from a far-away white or black-board and writing on paper?

Eye teaming skills: Are your child’s eyes working together as a focus unit -do they come together for proper eye alignment for reading?

Binocular vision skills:  Are your child’s eyes blending visual images from both eyes into a single, three-dimensional image?

Visual perceptual skills: Does your child identify and understand what s/he sees, co-relating importance, connecting with previous visual memorized information?

Visual-motor integration:  Is the quality of your child’s eye-hand coordination balanced?  Visual-motor integration is important not only for legible handwriting and the ability to efficiently copy written information from a book or board but also for sports. Deficiencies in any of these can be detrimental to a child’s learning ability and / or school performance.

Vision Problems Do Affect Kids Learning

Undetected learning-related vision problems in children are common.  A child with an untreated vision problem may be misdiagnosed with behavior problems or ADHD/ADD when in reality they have a vision problem. Vision problems, in extreme cases, ignored or misdiagnosed, can become the true root cause of a child becoming the victim or aggressor in a school bullying tragedy.

Left untreated, vision problems will hinder your child's learning in school. Studies have shown that at least 13% of children between the ages of nine-thirteen suffer from moderate to severe convergence insufficiency, the ability to bring one's eyes together, which is crucial for good reading. Studies demonstrate clearly that one out of four school-age children suffer from at least one learning related vision problem.

Learning-Related Vision Problems

Signs and Symptoms

Some of the most common roadmap symptoms of learning-related vision disorders are:

  • Double vision, particularly during or after reading
  • Poor handwriting
  • Hyperactivity or recklessness during class
  • Word and letter reversals
  • Easily distracted during reading
  • Poor reading comprehension
  • Poor overall school performance
  • Circumventing of reading
  • Blurred vision, especially after reading or working closely
  • Eye Strain or frequent headaches

Call us to schedule a comprehensive child’s vision exam if your child exhibits one or more of these signs or symptoms and is exhibiting these types of problems in school.

Comprehensive Child Vision Exam

A comprehensive child's vision exam includes tests performed in a routine eye exam, plus specific additional tests for detecting learning-related vision problems.

Extra tests would include accommodation, binocular vision, and ocular motility testing. In addition to these, depending on the type of problems your child is having, we may recommend other testing, either in our office or with a child’s vision and/or vision development specialist.

Vision Therapy

Special reading glasses or vision therapy may help your child if s/he has a learning-related vision problem that cannot be corrected with regular glasses or contact lenses. Vision therapy entails eye exercises and other activities especially tailored for each patient to improve vision skills.

Learning Disabilities and Vision

Although children with learning disabilities may also have vision problems that are contributing to their difficulties in the classroom, vision therapy is a treatment for vision problems; it does not correct a learning disability. A child's learning ability and school performance may indicate learning disabilities and/or vision problems.

Once your child’s comprehensive vision exam is completed, we will advise you about whether a program of vision therapy could be helpful. We will refer you to a children's vision or education/learning specialist if we do not provide the specified additional services your child needs.

We also treat a number of other eye conditions which can also be detrimental to learning, as well as quite serious if not treated promptly.

Nonprescription Sunglasses

Everyone should have a good pair of sunglasses. Whether you wear prescription eyeglasses or not, sunglasses are important for every age, race and gender. While sunglasses may be considered a must-have fashion accessory, even more importantly, they play a critical role in protecting your eyes from UV (ultraviolet) and other harmful radiation from the sun. They also shield your eyes from wind, dust and debris that could cause discomfort, dryness or damage.

Sunglasses should be worn in the winter as well as the summer and should be 100% UV blocking. This doesn’t mean that you have to pay a fortune for your shades. Even cheaper brands of sunglasses are made these days with full UV protection, so take the extra time to ensure you select ones that do offer full protection from the sun’s rays.

Frame Materials

Sunglass frames are made in a wide variety of materials from plastics and acetates, to wood and natural materials to metals, such as aluminum, steel or titanium. Before you select a pair of frames, think about your lifestyle and what type of material will be most suitable for you. If you live an active lifestyle, sturdy and durable frames are a must. If you have sensitive skin, look for a pair made with hypoallergenic material that is light and fits comfortably. Make sure you select a pair that fits well, looks good and properly blocks the sun to ensure that you feel confident and comfortable when you are wearing them.

Sunglasses Shapes

Sunglasses serve as a combination of function and fashion and therefore come in a plethora of shapes and styles. Sunglasses are often larger than eyeglasses to cover more surface area and prevent sunlight from entering around the lenses. While fashion sunglasses are made in all of the latest styles from aviator to cat eyes, round, square and oversized, sports sunglasses are generally more durable and broad, often in wraparound styles that prevent sunlight from entering from the sides as well. Wrap-around frames are a good option for athletes, fishermen and bikers that spend a lot of time outdoors in the sun.

Lenses

Lenses are the most important part of any pair of sunglasses. As mentioned above, all lenses should block 100% UV rays but beyond that there are many options for sunglass lenses. Polycarbonate or trivex lenses are impact-resistant to increase safety during sports and outdoor activities. Polarized lenses help to reduce glare and are particularly helpful during activities on or near the water such as boating, fishing or beaching. Anti-glare and anti-scratch coatings are also beneficial to maintain your best vision in a variety of conditions.

For the fashion conscious there are a number of colors and reflective coatings available for sunglass lenses. It’s best to choose the lenses that allow for the most accurate color vision with the least amount of distortion to ensure they don’t obstruct clear vision.

While it’s important to choose sunglasses that you like from a style and appearance perspective, it’s also important to pay attention to comfort and fit. Here are a few tips for purchasing sunglasses that fit well for maximum comfort and sun protection:

  1. Make sure the lenses completely cover your eyes and provide extra coverage above and to the sides.
  2. The frames shouldn’t pinch at your temples or the nosepiece and should be wide enough for your face.
  3. Ensure that the frames aren’t too wide and stay in place when you move your head around.

Sunglasses for Prescription Eyeglass Users

If you wear prescription eyeglasses there are a number of options for sun protection. These options include prescription sunglasses, photochromic lenses (which turn from clear lenses to dark when you go outside), clip-ons, fitovers (which are sunglasses that go over your prescription eyewear) or wearing contact lenses with plano (non-prescription) sunglasses. Speak to your optician to determine the best option for you.

Prescription Sunglasses

Sunglasses are an important way to protect your eyes and ensure clear and comfortable vision when you are on the go. In addition to causing temporary vision loss, the sun’s bright rays can lead to long term eye damage. Ultraviolet radiation from the sun can also cause sunburns on the eyes and over time, can lead to diseases such as macular degeneration.

For those who wear prescription eyeglasses, sun protection is available in a number of options including prescription sunglasses, photochromic lenses or eyeglasses with clip-on sunglass lenses. The best solution depends on your personal preferences, comfort and which option fits in best with your lifestyle.

Prescription Sunglasses

These days, sunglasses are not only highly fashionable but remarkably functional for a wide variety of activities. Sport and athletic sunglasses for example provide eye protection, reduced glare and better contrast to improve performance in a range of outdoor conditions. Individuals with prescription eyewear can also benefit from the advantages of these specialty eyewear by purchasing prescription lenses.

Prescription sunglasses are available for virtually all vision prescriptions including those for farsightedness, nearsightedness and astigmatism, as well as bifocal and progressive lenses. Almost any pair of sunglasses can be fit with prescription lenses as long as the shape of the lens doesn’t distort vision (which happens for example with extremely wide wraparound lenses). Therefore if the latest pair of designer sunglasses catches your eye, there should be no problem in fitting a prescription lens to the frame.

You can also get prescription lenses in most lens materials and with most lens coatings, including polarized lenses (for glare protection), tinted lenses, anti-scratch coatings, polycarbonate or Trivex lenses (for extra durability) and more.

Even for those individuals who do wear contact lenses, prescription sunglasses are a fantastic solution when you prefer not to wear your contacts, such as when your eyes feel dry or irritated (during allergy season or in dusty or sandy locations for example), when you are going swimming (it’s advised not to wear contact lenses swimming in any body of water due to risk of infection) or when you just don’t want to deal with the hassle of contacts. Prescription sunglasses give you yet another option for comfort, safety and great vision.

Photochromic Lenses

Photochromic lenses are another alternative for the prescription eyeglass wearer. These lenses darken in response to sunlight turning your regular prescription eyewear into prescription sunglasses. Photochromic lenses are a convenient solution for glasses wearers who find it a hassle to carry around two pairs of glasses. No matter what shape or style, you can protect your eyes and spruce up your outdoor look or your sports performance with a pair of prescription sunglasses.

Sunglasses for Kids

Many parents don’t know the importance of sunglasses for children and don’t stress that they wear them, especially given the hassle involved in encouraging children to wear them and take care of them properly. However, studies show that since we spend so much time outdoors and in the sunshine as children that by the age of 18, our eyes and body have absorbed half of our lifetime ultraviolet radiation (UV) exposure. This makes the use of sunglasses and proper UV protection even more critical for children.

Risks to children’s eyes from overexposure to the sun can be short term and long term. Short terms risks include photokeratitis also known as “snow blindness” which is essentially a sunburn of the eye. Photokeratitis can cause temporary vision loss for up to 48 hours. Pterygium is another condition, also referred to as “surfer’s eye,” which causes an itchy, swollen growth to form on the surface of the eye. Pterygium often require surgery to remove.

Long term UV damage is known to be a risk factor for a number of eye diseases including cataracts (a clouding of the lens of the eye that causes vision loss) and age-related macular degeneration, which also causes permanent vision loss and low vision, as well as cancer of the eye, eyelid or the skin around the eye. Wearing sunglasses with wide or wrap-around lenses will protect not only your eyes, but also the area around your eyes from UV exposure and damage. Since these diseases can be caused by an accumulation of UV exposure over a lifetime, it is important to start preventative measures early, by getting children in the habit of wearing sunglasses when they are outside.

Quality sunglasses for children are easy to find these days, you just have to know what to look for. Firstly, you want to make sure that the lenses have 100% UVA and UVB protection and block UV absorption up to 400 nanometers. You also want to ensure that the frames completely cover as much of the eye and its surrounding as possible. Many frames will come with a band to help hold the sunglasses in place and prevent loss. You may also choose to buy polycarbonate or trivex lenses, as they are more durable and impact resistant which is particularly helpful for active kids.

Children that already wear eyeglasses can consider photochromic lenses (which darken in response to sunlight) which basically gives them two pairs of glasses for the price of one. With photochromic lenses, you don’t need to worry about your children switching, and misplacing glasses when they go in or outdoors.


As with any glasses purchase, ask your optician about the policy for lost or broken sunglasses. Make sure you get a strong storage case and discuss with your child the best ways to keep the sunglasses safe and secure.


Lastly, let your child be involved in the process of selecting sunglasses, as any child will be more enthusiastic about wearing shades that he or she picked out and loves.

Performance and Sport Sunglasses

Whether you are out on the field, the golf course, the waves or the mountains, you want your sunglasses to protect your eyes from the sun and enhance your visual experience. Sports and performance sunglasses are more than sun protection, they need to be designed for optimal, fit, comfort, acuity and strength, based on the demands of the sport or leisure activity you pursue.

Each element of your sports eyewear needs to be designed for active wear and to stand up to the tests of extreme weather conditions, rough play, impact and of course the sun. If you are fishing for example, you need anti-glare protection in your lenses for when the sun’s bright rays reflect off the water, you need a broad frame to keep out the mist and wind and you need strong frames and lenses for impact resistance. Most importantly, depending on your sport of choice, your glasses should assist in creating an enhanced visual experience so you can see and perform at your best.

Performance Sport Lenses

The first consideration when selecting your sports eyewear is the lens. You likely want a lightweight, strong and durable lens that can withstand impact from debris, other athletes, balls or falls. The leading lenses in this arena are polycarbonate or trivex lenses which are made from highly impact resistant plastic that has built-in UV protection.

Glare can be an annoying and uncomfortable distraction in outdoor activities, which can reduce vision and have a negative impact on sports performance. Polarized lenses will help to reduce the glare that is reflected off of wet, icy or shiny surfaces. Lens tints and coatings (such as anti-glare or anti-scratch coatings) can also help to improve visual clarity and can serve to reduce glare and to enhance contrast sensitivity to improve vision and therefore performance in certain outdoor activities. Some sports sunglasses come with interchangeable lenses of different tints to allow you to choose the contrast that most suits the conditions you are playing in.

Sport Frames

When selecting sports sunglass frames, the most important consideration is whether they have a comfortable and secure fit. Look for a pair that is strong and durable, yet lightweight and that doesn’t press into your face and cause discomfort at the temples or the bridge of the nose. For some sports like snowboarding, sports goggles might be the best option for the weather conditions and specific nature of the movement. Some frame options come with grips on the nose pads or temples to avoid slippage, particularly when you perspire.

Sports sunglasses are available in a variety of styles, shapes and sizes and the type that is best for you largely depends on the activities you participate in and what they demand. It is best to consult with your eye doctor or optician to get a full picture of your eye, vision and athletic needs in order to find the best pair of sports sunglasses for you.

Our Eyeglasses

Modern eyewear serves a dual purpose. In addition to being a vision-correcting medical device used to enhance your safety and quality of life, eyeglasses have become a major fashion accessory. Therefore, when it comes to selecting eyeglasses there are many important factors to consider.

The Frame

Frames are made from a large variety of materials ranging from acetates and hard plastics to metals and metal alloys. The quality of frame materials is very high nowadays with many cutting-edge manufacturers investing heavily in developing new innovations and materials to make stronger, more flexible, lighter and more beautiful frames.

In considering the optimal material for your eyeglass frame, your lifestyle plays a big role.  Children and those with active lifestyles require durable and flexible frames that are resistant to breaks from hits and falls.  Those who have skin allergies need to seek out frames made from hypoallergenic materials such as acetate, titanium or stainless steel.  Other characteristics of frame materials to consider are the weight or flexibility of the material as well as the price.  Many designers also use wood, bone or precious metals to adorn frames and add an extra .

Hinges and nosepads also play an important role in durability and comfort of your frames. Children in particular can benefit from spring hinges and nosepads which can keep the frames from slipping off. Rimless or semi-rimless glasses are also an option for those that durability is not a primary concern.

Frame size is a very important factor in frame selection.  Frames should fit well and not slip off the nose or be too tight and press against the temples or the sides of the nose.

More and more top fashion design brands are coming out with designer eyewear collections to suit every taste and style.  Frames come in all colors, sizes and shapes so the choices are endless in finding a frame that suits your personal style and looks good with your face shape and coloring.

Lenses

Even though people spend much more time focusing on frame selection, as a medical device, the lenses of your eyeglasses are the most important part.  It is therefore very important that you obtain your lenses (and therefore your glasses) from a reputable source.  It is always best to buy eyeglasses through an eye doctor who is able to check that the lenses are made and fitted properly to ensure your best possible vision.

There are a number of variables to consider in selecting lenses.

If you have a high prescription which may require thicker lenses, you may want to ask for aspheric lenses which are thinner than normal lenses.

There are lenses that are made from materials that are more durable and shatter-resistant such as polycarbonate or trivex, which can be useful for children or sports eyewear.

Photochromic lenses can serve as eyeglasses and sunglasses as the lenses darken when exposed to the sunlight to block out the sunlight and UV rays.

Polarized lenses create greater eye comfort by reducing glare specifically from the water or snow and are great for sunglasses for those that spend time outdoors.

There are also a number of coating options that you can add onto lenses to enhance certain characteristics such as anti-reflective coatings, anti-scratch coatings or UV coatings to reduce exposure from the sun.  Adding a coating may require special cleaning or treatment so ask your eye doctor or optician about special instructions.

Eyeglasses Over 40

Once you approach age 40 you are likely to begin to experience presbyopia which is the loss of the ability to focus on close objects.  This happens as the eye begins to age and can easily be corrected with reading glasses. However, if you already have an eyeglass prescription for distance vision, you will need a solution that enables you to see your best both near and far.

There are a number of options available for presbyopes including bifocals, multifocals and progressive lenses with new technology improving the options all the time.  You should speak to your eye doctor about the best solution for your individual needs.

Whether they are for a child’s first pair, a second pair of designer frames or a senior with a complicated prescription, you should always consult with your eye doctor for a new pair of glasses.  Ultimately, your eyeglasses have a job and that it to help you to see your best to get the most out of every day.

Polycarbonate Lenses

Polycarbonate lenses are high index lenses that are known primarily for their exceptional impact resistance and anti-scratch coating. If you or your children are always bumping, scratching or dropping your eyeglasses, this is the material for you. Up to 10 times more impact resistant than standard plastic eyeglass lenses, polycarbonate is a first-rate option for people with an active lifestyle. Developed in the 1970s, polycarbonate has been protecting eyes for quite a while.

Superb Eye Safety

If you regularly engage in sports or physical activity, these tough, durable lenses provide an extra degree of safety for your eyes.
