Anti-Reflective Coating: Enhancing How You See the World and How the World Sees You

Anti-reflective coating (also known as anti-glare or AR) is a special treatment for eyeglasses where a very thin coating is applied to both sides of the lenses. Anti-reflective coating enhances both clear vision and the appearance of eyeglasses by eliminating reflections of light from the front and back surfaces of lenses.

Removing reflections from the surface of lenses reduces glare which makes it easier see while driving at night. In addition to reducing glare, AR allows more light to reach the eyes instead of being reflected away. This enhances comfort and visual clarity when using such things as a smart phone, a tablet, a computer or simply reading a book.

Anti-reflective coating also improves the appearance of eyeglasses. Lenses without AR coating create reflections that   obscure the eyes of a person wearing glasses. Anti-reflective coating enables the lenses in a pair of eyeglasses to appear almost invisible.

Anti-reflective coating can be a great choice that allows a pair of eyeglasses to perform and look their best. Talk to your eye care and eye wear professional about anti-reflective coating for your eyeglasses.

Slim, Nice Figure, Ideal Weight and Attractive. What’s Being Described Here?

hi index eyeglass lensesIf you answered eyeglass lenses, you are correct!

Hi-index lenses offer people who wear eyeglasses with lens choices that are thin, light and attractive.

For people who have strong prescriptions for nearsightedness, farsightedness or astigmatism, hi-index lenses are a great way to avoid lenses that are thick, heavy and distort the natural appearance of your eyes.

The lenses in a pair of eyeglasses correct vision by bending or refracting light as it passes through each lens.  With conventional plastic and glass lenses, the more light that needs bent, the alternatives to thick eyeglassesthicker the lenses must be.

Hi-index lenses are different.  Here’s how they work and the benefits they offer:

Increased Light Bending Abilities

Hi-index lenses are made of a special material that is able to bend or refract light much more efficiently than conventional lenses.  This means less lens material needs to be used to bend the appropriate amount of light that corrects vision.

Thin Construction

Due to the increased ability to bend light, hi-index lenses are much thinner than conventional plastic and glass lenses. Therefore, the profiles of eyeglasses are not dominated by thick lenses when hi-index lenses are used.

Comfortable Wear

Because less material is used with hi-index lenses, they do not weigh as much as conventional lenses. This makes them light weight and comfortable to wear.

The fashions of today’s most popular frames have either very thin rims or no rims at all (rimless frames). The thickness of the lens becomes very important with these styles of eyeglass frames.  When lenses are too thick, the balance between the frames and lenses becomes disproportionate, resulting in a pair of eyeglasses that are not as cosmetically appealing as they could be with hi-index lenses.

Ask Your Eye Doctor About Hi-Index Lenses

Discuss hi-index lenses with your eye doctor to see if they are an option for you and your vision correction needs.  They may provide you with the function, comfort and appearance you desire in a pair of eyeglasses.

Three Main Types of Retinal Detachment

Eye anatomy and eye careThe retina is a thin, light-sensitive membrane covering the rear of the eye. It’s the part of the eye where images are focused by the cornea and lens. The images displayed on the retina are transmitted to the visual centers of the brain by the optic nerve. In fact, the retina is technically part of the body’s central nervous system and is considered brain tissue.

Approximately 95% of the retina is responsible for side vision or peripheral vision. The remaining 5% located in the very center of the retina is known as the macula and allows for central vision.

If the retina becomes damaged or separates from the back wall of the eye, it’s a condition known as retinal detachment.  When a retinal detachment occurs, it’s a serious condition that needs attention. A retinal detachment causes the retina to separate from its blood and nutritional supply which could lead to loss of peripheral vision, central vision or both.

There are three (3) main types of retinal detachment:

retinal detachmentRhegmatogenous Retinal Detachment (RRD)

This is the most common type of retinal detachment. The term rhegmatogenous means “arising from a rupture or a fracture”.  Rhegmatogeous retinal detachment occurs when there is a hole or a tear in the retina. The break in the retina allows the gel-like substance from the vitreous cavity of the eye to seep through the opening causing the retina to detach from the eye wall.

Tractional Retinal Detachment (TRD)

A tractional retinal detachment is a retinal detachment caused by the gel like substance within the vitreous cavity of the eye pulling on the retina which eventually causes the retina to detach from the rear eye wall.

Exudative Retinal Detachment (ERD)

An exudative retinal detachment occurs as a result of a leak under the retina which allows the gel-like vitreous substance to enter behind the retina. These types of leaks are typically caused by inflammation.

Symptoms of Retinal Detachment

Flashing lights and eye floaters are common early symptoms associated with a retinal tear or retinal detachment.  If a dark shadow or dark curtain obscures a portion of vision, this is also an indicator of retinal detachment.  Anyone who experiences these symptoms should schedule an exam with their eye doctor immediately.

Children Shouldn’t Be Scared of Cycloplegic Refraction

Cycloplegic refraction explained by Shawnee OpticalThe term “cycloplegic refraction” certainly sounds intimidating. Tell this to a child and it can be understandably frightening.  As with many unknowns, a little knowledge and setting expectations can take away unnecessary fears.

What is Cycloplegic Refraction?

Cycloplegic refraction is nothing more than a procedure used by eye doctors to gain an accurate reading of a person’s refractive error to help them see more clearly and comfortably.

Refractive error is the inability of a person’s eye to bend light correctly. If light is not refracted properly as it enters the eye, the result is distorted vision.

During the testing in an eye exam, a patient’s eyes may auto- focus, or accommodate, which leads to inaccurate and inconclusive testing results. When your eyes are auto focusing, your eye doctor cannot decisively determine your true eye prescription.

Cycloplegic refraction temporarily stops the eye’s ability to auto focus allowing your eye doctor to correctly ascertain your prescription and optimize your ability to see clearly and comfortably.

Why is Cycloplegic Refraction Common with Children?     

Cycloplegic refraction is often times used with children. Children have a strong ability to unknowingly accommodate, or auto-focus, their vision which makes eye exams yield inaccurate or incomplete results.

As described above, cycloplegic refraction briefly suspends a child’s ability to auto-focus. This provides the eye doctor with an uninterrupted opportunity to obtain an exact reading on the child’s refractive error and derive a true and accurate prescription.

What to Expect with Cycloplegic Refraction

Cycloplegic eye drops are placed in the patient’s eye to prevent the ciliary muscle of the eye from contracting and relaxing. This muscle is attached to the crystalline lens of the eye and controls the shape of lens.

There are a variety of cycloplegic eye drops which differ in strength and duration.  When these eye drops are applied, it causes the pupils to dilate and vision will become blurred for a few hours. Some patients also experience tearing and redness in the eyes.

Not Just for Children

Cycloplegic refraction is not exclusively for children. Adults sometimes need this procedure performed to gain a more precise eye prescription. If eyeglasses do not provide the level of clarity needed, this procedure may be appropriate to deliver a refined eyeglass prescription.

Eye Glasses: a History and the Future

eye glasses Shawnee OpticalEye glasses are in the process of changing significantly. The eye glasses of tomorrow will be noticeably different than the variety of lenses and frames being offered today.

Eye Glasses History Lesson

Historians generally give credit to Italian monks for fabricating the first pair of eyeglasses at some point between the years 1285 – 1290. These spectacles, as they were commonly called, were used for reading.  Eye glasses to correct distance vision are estimated to have been crafted in the early 1400’s.

One of our Founding Fathers, Benjamin Franklin, invented bifocal lenses in the year 1784 which allowed for correction of both distance vision and near vision in the same lens. An Englishman, Sir George Airy, designed lenses to correct astigmatism in 1825.

Trifocal lenses which have three specific powers (one for near vision, one for intermediate vision and one for distance vision) were produced by inventor and musician John Hawkins in the year 1826.

In 1958, Essilor International introduced progressive multifocal lenses which further enhanced lenses with multiple powers for distance, intermediate and near vision.

Innovations in Eye Glasses

Technology is playing an increasing role in the evolution of eyeglasses. Lenses have been developed and continue to be refined whereby the entire lens adjusts with your vision needs.

Electronic eye glasses have been designed with a special type of lens filled with a clear crystal liquid layer that can be electronically controlled automatically or manually. A touch of the finger to the side of the frames or a tilt of the head in a certain direction changes the entire lens to serve your vision needs. If you want to read something, a tilt of the head downward will cause the eyeglasses to automatically adjust the entire lens for near vision. A split-second swipe of the finger across the temples of your frames will allow you to look up from what you were reading and see a distant object clearly through the convenience and comfort of the entire lens.

Electronic glasses are powered by a battery and need to be re-charged. They are currently offered to the public but as you may guess with any emerging technology, they are rather pricey today.

Computing via Eyeglasses

While not targeted towards vision correction, electronic display eyeglasses are being developed that use eye movements to control presentation of information. These eyeglasses contain a microchip that takes data from a PDA (Personal Digital Assistant) and displays it directly on the person’s retina, creating an illusion that the images and text are a few feet away. Eye movements can control menus, search information, play video and conduct many other tasks routinely performed on desktops, laptops and mobile devices today.

This advancement in eye wear is still in the prototype phase. The technology is not yet at a point where its purchase and every day use are feasible.

Discuss emerging eye wear technologies that may serve your unique vision needs, lifestyle and budget with your eye doctor at your next eye exam. The options and the choices are changing.

Back to School Checklist: Make Your Student’s Eye Care #1

The start of another school year is just around the corner. Many of us have made our list of things we need to do and purchase in order to properly prepare our children for another year of formal education. When you’re out visiting the mall buying new clothes or filling up your shopping cart with notebooks, pens, pencils, backpacks, organizers and similar school supply items, don’t forget to squeeze in a worthwhile visit to the eye doctor for an exam. In fact, eye care for your student(s) should be at the top of your list. Here’s why:

The Best Learning Method

Extensive research in educational theory has shown that visual learning is among the very best methods for teaching students of all ages how to learn. According to research, students remember information at a much higher rate when that information is presented visually. The optimal presentation for learning and retaining information is a blend of (1) visually seeing the information; (2) verbally saying or hearing the information and; (3) physically writing the information.

Visual Clarity Affects Learning

How do you react when you see a complex diagram or an abundance of written text? Is your first reaction to jump right in and study it further or do you reluctantly approach it? How do your children (students) approach information like this?

Many studies show that visual clarity of information being studied greatly impacts the ease at which it is learned. Whether it’s a chart on a projection screen, an article in a newspaper or a page in a textbook, most people will have a positive approach to the information if they can see it clearly and easily. This has huge implications on learning. Positive or negative feelings and perceptions determine the levels of motivation, comprehension and retention that will be achieved.

Crisp, clear and accurate vision is the firm foundation from which successful academic performance can be built.

Easy to Read is Perceived as Easy to Do

Studies show that when information and instructions are easy to read, people tend to think it will not take much time and effort and dive right in. On the other hand, when information and instructions are not easy to read, people perceive the task to be difficult, time consuming and are reluctant to approach it.

Communicate with Your Eye Doctor

Talk to your eye doctor and discuss ways to enhance all areas of your child’s visual health. More than likely, it will enhance his or her academic performance and confidence.  This applies to students of all ages.

Special Vision Needs for Internet and Cellular Use

We live in a digital world where the demands placed upon our eyes are growing exponentially. These demands now start at a very young age and continue throughout every stage of our life. We depend upon a TV, computer or smart phone at school, at work and to socialize with family and friends.  The importance of seeing clearly and comfortably at a range of approximately 1-3 feet is critical to everyday life.  This significance will only grow in the future as more and more of life’s tasks, functions and pleasures are conducted electronically.

Beyond Reading Glasses

Extended periods of time watching videos on YouTube, posting on facebook, searching on Google, tweeting on Twitter, networking on Linkedin, texting a friend or chatting with a family member commonly lead to health problems such as tired eyes, headaches and neck pain. To address these conditions, computer hardware and software manufactures as well as cell phone and smart phone manufactures are constantly developing new features, screen displays and fonts that are more eye-friendly.  However, more specialized eyeglass lenses beyond the capabilities and features of traditional reading glasses may be required to properly and effectively utilize technology and prevent chronic health conditions. Bifocals and Progressive lenses are not designed for computer and smart phone use. They may cause eye strain as well as neck and back pain as you adjust your body in the quest to find a position where your vision is clear and focused through your lenses.

Visual Fatigue Syndrome

Visual Fatigue Syndrome or VFS is typically caused by focusing on objects in the 1-3 feet vision range for extended periods of time. Symptoms of Visual Fatigue Syndrome may include Tired Eyes, Eyestrain, Blurred Vision, Dry Eyes, Burning Eyes, Headaches, Neck Pain and Back Pain.  More and more people are suffering from VFS due to the demands of their digital world. VFS can reduce your productivity and your ability to concentrate which often times leads to increased stress.

Talk to Your Eye Doctor

A candid conversation with your eye doctor can help you immensely with the demands of today’s technology as well as avoiding or reducing the effects of Visual Fatigue Syndrome.  It’s important to discuss your career and lifestyle demands with your eye doctor, especially as it relates to your use of technology equipment. What specific equipment you utilize on daily basis and the duration of use can be particularly helpful. For example, tell your eye doctor that you spend 6 hours a day working at a computer with a 15” monitor or you spend the majority of your day using an iPad.  Armed with this type of information, your eye doctor can offer valuable guidance on preparing your environment for optimal vision such as proper lighting and how to position your equipment.  In addition, your eye care professional can also recommend and prescribe special lenses that match the demands of your digital lifestyle.

Eyeglass Lenses Designed for the Computer and Visual Fatigue

To keep up with the modern world and its visual demands, eyeglass lens manufacturers are continually developing new specialty lenses.  Computer lenses provide a wide “near” area in order to see the entire computer screen clearly and comfortably with a small “distance” area so you can see across the room.  Anti-fatigue lenses are specialized lenses targeted at improving the “near” vision needed to operate a laptop, tablet computer or smart phone  and relieving the symptoms of visual fatigue such as burning eyes,  blurry vision, headaches and watery eyes.

Technology greatly improves our productivity and ability to communicate with others.  Make sure you are equipping yourself with the proper eyewear to keep up with the demands of your digital life and promote maximized eye health.
