Depending on the material used to make a lens, between 4-16% of light striking the lens surface is ordinarily reflected back or "lost" by the lens. A multi-layercoating of metal oxides, just a few microns thick can significantly increase the amount of light transmitted through the lens by decreasing the percentage of light lost to reflection.
Contact lenses are an excellent vision correction option for people of all ages. According to data provided by The Vision Council in September 2014, approximately 16 percent of the U.S. population (roughly 39.3 million adults) report wearing contact lenses at least part time.
Recent advances in lens materials and care products have made contact lenses more comfortable than ever. Even people who have had problems wearing contacts in the past often are good candidates for contact lenses today.
Two common questions we hear in our office from parents are, "Can kids wear contact lenses?" and "How old does my child need to be to wear contacts?"
You may be surprised to discover that contact lenses are often prescribed to correct vision problems in very young children–even infants. However, while physically there may not be a minimum or recommended minimum age for wearing contact lenses, it's important to ask whether contacts are appropriate for your child.
The following questions and tips can help you evaluate whether your child is a candidate for contact lenses.
Over 100 million people around the world enjoy the convenience and freedom of contact lenses. Although the majority of contact lens wearers in the U.S. are female and under 40, more recently, contact lenses are being chosen by a wider range of age groups for their greater convenience in certain situations such as sports and recreation. In these cases, they are often used interchangeably with glasses, giving people the flexibility to use the most suitable option for the activity at hand.
Progressive lens "Zones"
Progressive lenses, sometimes referred to as "no-line" bifocals, provide vision correction for the three basic vision zones - distance vision, intermediate vision, and near vision. Because they provide vision in these three zones, they are often thought of as a type of trifocal.
In reality, progressive lenses are neither a type of bifocal or trifocal - they are "aspheric" in design, which means the curvature (and focusing power) gradually changes from the top of the lens to the bottom. It is this gradual change or "progression" in power from top to bottom that gives rise to the name "progressive."
hether you're new to contact lenses, or you've been wearing them for years, it's important to put the following tips into practice.
Putting in and Removing Your Contact Lenses
First, wash and dry your hands thoroughly.
Whatever is on your hands when you touch your contact lenses could end up in your eyes. That's why it's important to thoroughly wash your hands with antimicrobial soap. Then dry your hands thoroughly with a clean towel before handling your contact lenses.
Also, avoid using cream or oil-based soaps and lotions before touching your contacts, as these can contaminate your lenses or leave an oily film.
Predicting the unpredictable – How to find your fall fashion groove
Fall weather usually is so unpredictable. It can be breezy cool in the morning and Miami hot by afternoon. Or it can be freezing. You just never know. Accordingly, fall fashion often is a matter of mixing, matching and melding layers of varying styles that can be peeled off or added according to the sometimes–crazy fluctuating temperature.
Your guide to holiday shopping bliss
Do you have all of your holiday shopping done yet? It's never too soon to consider the inevitable: holiday shopping. If holiday shopping tends to sneak up on you each year, you're not alone. The mad rush in December can nearly suck the "ho, ho, ho" right out of all those well–meaning gift givers.
If you're looking for a way to sidestep the madness and avoid the mayhem, Keisha Lancelin, public affairs director with CW television in Atlanta, has put her 15 years as a consumer/community reporter to work for you:

Aquaform® Technology, a CooperVision® technological breakthrough, allows Biofinity® lenses to have superb breathability, combined with higher moisture content. This keeps you comfortable and your eyes clear, whiter and healthier. What's more, all Biofinity lenses have a smooth, naturally wettable lens surface that resists deposits, so you get incredible comfort and clarity that lasts all day.
Available in sphere lenses for near/farsightedness. If you have astigmatism or presbyopia, try our toric and multifocal lenses for impossibly clear vision.
If you have dry eyes, there may be a simple way for you to treat the problem and get a number of other health benefits, too — start taking a daily fish oil supplement.
Fish oils and fatty fish — such as salmon, tuna and sardines — are excellent sources of omega-3 essential fatty acids (EFA) that are important to health.
Fatty acids are important for the normal production and functioning of cells, muscles, nerves and organs throughout the body. Fatty acids also are required for the production of hormone-like compounds that help regulate blood pressure, heart rate and blood clotting.
Why you should laugh every day.
Lillie Shockney has a coffee mug on her desk that she looks at every day featuring a cartoon drawing of Noah's Ark. The ark, which is way out in the ocean, depicts a bunch of animals on deck staring back at the shore with perplexed looks on their faces. Back on shore are two purple characters that resemble an odd–shaped Barney–like character with worried looks on their faces. The caption reads: "Oh crap, was that today?"
Tinted Eyeglass Lenses If you wear glasses, remember that they not only help you see but they contribute to how others see you as well. The proper lens tint can make working at a computer more comfortable, reduce glare when driving, allow a target shooter to see the target more clearly, enhance the wearer's appearance by hiding fine wrinkles around the eyes or simply help the wearer make a desired fashion statement.
If you've been stuck wearing thick glasses because of severe nearsighted or farsighted vision, we have good news. Soft, comfortable CooperVision Biofinity® XR contact lenses are now available.
The Biofinity XR lens is the first of its kind that combines high breathability with all–day comfort characteristics required for wearers with more challenging prescriptions. The "XR" stands for extended range–a range of powers from +8.50D to +15.00D for farsighted vision and -12.50D to -20.00D for nearsighted vision. Trust us when we say that those power ranges are prescribed to correct severe levels of farsighted and nearsighted vision.
If you have cataracts and need surgery to restore your vision, fear not -- cataract surgery is one of the most frequently performed surgeries, and modern cataract surgery is safer and produces better visual outcomes than ever before.
Still, you should be well informed about what to expect before, during and after your cataract surgery, and which of the many types of intraocular lenses available these days is the best choice for your needs.
Cataract Surgery Basics
In cataract surgery, the cloudy lens inside your eye is removed and replaced with an artificial lens -- called an intraocular lens, or IOL -- to restore clear vision.
High index lenses are manufactured with modern materials that make them thinner and lighter in weight than was previously possible. These new lenses provide visual and cosmetic benefits for stronger corrections because they are thinner and flatter than conventional lenses. This greatly reduces the "Coke-bottle" effect associated with thicker, conventional lenses and provides improved clarity across the lens surface, especially in higher lens prescriptions.
Why can high-index lenses be made thinner?
The benefits of modern-day computing and the Internet have led to a group of eye and vision-related problems. Collectively, this group is called Computer Vision Syndrome or CVS. CVS is caused by spending an extended amount of time looking at computer screens and other digital devices.
Between work and home computers, laptops, tablets and smartphones, it's easy to log a lot of hours staring at a screen. (We've certainly experienced it ourselves!)
What does OD and OS Mean? The first step to understanding your eyeglass prescription is knowing what "OD" and "OS" mean. They are abbreviations for Oculus Dexter and Oculus Sinister, which are Latin terms for right eye and left eye. Your eyeglass prescription also may have a column labeled "OU." This is the abbreviation for the Latin term OculusUterque, which means "both eyes."
Sphere (SPH). This indicates the amount of lens power, measured in diopters (D), prescribed to correct nearsightedness or farsightedness.
