The single vision lenses are prescribed for corrections either only for distance vision or only for near vision (items up close). This basic lens has the same optical focal point or correction over the entire span of the lens, hence it's called the "single vision" lenses. Vizio Optic offers you many options for top quality single vision lenses for your glasses. Single vision lenses come in several forms: Plastic lenses, Polycarbonate lenses, High Index lenses, Transitions lenses, Polarized lenses, and other sun wear options.
Aspherics are ideal lenses for stronger prescriptions because they are flat and thin. They also look better because they reduce the farsighted eye magnification and nearsighted eye minification.
Some time over the age of 40, you will begin noticing the symptoms of presbyopia. This means that you begin losing the ability to naturally change the focus of your eyes due to age. Multifocal eyeglass lenses can help you see better - they are the bifocal lenses and trifocal lenses that come in many configurations, depending on whether you sit at the computer all day or stay active outside. These lenses contain two or more lens powers in the span of you lens and it will help you see objects at all distances better. Ask us for help to assist you in choosing the right multifocal lens for you.
Progressive lenses are like multifocal lenses but without the lines inside of it. Please email or call us for us to assist you on the types of high quality progressive lenses that may suit you best including Zeiss and Varilux lenses.
When purchasing eyeglasses from us, it's important to consider protective coatings for the lenses. They will extend the life of the glasses while protecting the eyes. The following coatings are the most common and recommended:
An AR coating works by reducing reflections, halos and glare, presenting a more clear visual field for the eyeglass wearer. This can be especially helpful when driving at night.
This coating is similar to those used on lenses in cameras and microscopes. It is made up of mineral deposits that act as a barrier to reflected light. It also minimizes reflections on the lenses themselves, which makes them appear much thinner. When this coating is used on sunglasses, it is only applied to the back part of the lens to keep the front section from becoming too smudged.
As with AS coating, glasses with AR coating must be cared for with special solution and cleaning cloths. A well-cushioned case with hard outer shell will also prevent scratching and breakage.
Scratch Resistant Protection
Plastic lenses are revolutionary in that they are lighter than glass but they are also more suseptible to getting scratched. The life of plastic lenses can be extended with a scratch resistant coating. This type of coating is clear and firm and works best when applied to both side of the lens.
Most plastic lenses do come with scratch-resistance, however, this should always be confirmed by asking the optician, to be on the safe side. Plastic lenses also do well when cleaned with a proper solution and cleaning cloth. Never use Windex, plain water or paper towels. This is the main cause of scratched lenses that end up having to be replaced sooner.
Studies have shown that most of the damage to eyes caused by UV light happens before age 18. Too much UV exposure can lead to vision problems such as retinal damage or cataracts. Protection from UV light should start at an early age.
UV coating is invisible and very easy to apply to standard and sunglass lenses. For maximum effectiveness, sunglasses that offer 100% protection from UV/UVB rays are the best choice. It should be noted that certain cosmetics and medications can increase sensitivity to UV light. Check with the doctor and read all medication labels carefully.
Mirror or flash coatings are used primarily in sunglasses and offer nothing in the way of protection from glare nor do they make the visual field clearer. Some are very attractive with many choices for color such as copper, gold, silver and all the shades of the rainbow but their use is only cosmetic. UV and anti-reflective coatings are a much better investment that will actually protect eyesight.
While choosing the right protective coating for eyeglasses is very important, it is also vital to have regular eye exams by a licensed doctor of opthamology to ensure eye health. This is especially true after the age of 40 when many age-related changes such as presbyopia and macular degeneration can begin.
Key Types of Eyeglass Prescription Lenses
Many types of eyeglass prescription lenses are available for eyeglasses, and the type that a person should use will depend upon his or her specific needs.
Many people get by without prescription lenses because, other than for fine work, they see very well. Reading glasses provide them with the strength they need to read fine print in books or to thread the occasional needle. But other people find that they need eyeglass lenses that offer more power, durability, or flexibility.
Why You Need Anti Reflective Coating
If prescription eyeglasses are purchased today, chances are the lenses will have an anti-reflective coating. This coating will not only improve vision, but will also improve how the glasses look on the face. Someone looking at a person with the anti-reflective lenses will not see a blurry effect on the lenses. Often the position of the sun will totally obscure a person’s eyes if they are not wearing glasses with anti-reflective lenses. If they are wearing glasses with the coating, looking at their eyes will be as clear as if the person were not wearing glasses.
About Bifocal, Trifocal and Multifocal Lenses
If you find that your usual set of glasses is not enough, you may need bifocal lenses. Especially for those over the age of 40, presbyopia can be a reality. Presbyopia causes a person to have blurred vision when viewing things within a close distance, such as books, newspapers, and the computer screen. Hobbies such as sewing, knitting, and even simple tasks such as handwriting can be greatly hindered by presbyopia.
About Scratch Resistant Coating for Your Eyeglasses
Scratch resistant coating for your eyeglasses is one of the best investments you can make in your vision care. Cleaning the eyeglass lens with scratchy material or dropping your eyeglasses on the ground can cause an unsightly permanent scratch on the lens that can impair clear vision. By opting for scratch resistant lenses when ordering a new pair of eyeglasses or sunglasses, the wearer dramatically reduces the possibility that one or both lenses will be damaged by scratching.
Eyeglass Lenses That Relieve Computer Eye Strain - Computer Lenses
What You See is Out of Focus
The words that you are reading right now are about two feet away from your eyes, give or take a few inches. That places your vision in an intermediate zone, too far away for regular "near" vision reading and too close for the "distance" vision you would need to drive a car. Even if you already wear corrective lenses, constantly focusing on that middle area, as so many people are forced to do each day, can lead to computer eye strain and sometimes a condition called computer vision syndrome (CVS). With the invention of computer glasses or computer lenses, CVS no longer has to be a problem.
