Glare

is defined as a visual condition in which the observer feels either discomfort and/or exhibits a lower performance in visual tests (e.g. visual acuity or contrast sensitivity). This is produced by a relatively bright source of light–called the glare source–within the visual field. A given bright light may or may not produce glare depending upon the location and intensity of the light source, the background luminance, the state of adaptation of the eye or the clarity of the media of the eye. Although the term “glare” is used many times in a general sense, there are actually four different types of glare. The first type is Blinding/Reflected Glare. Blinding/Reflected Glare is light that is overwhelming and can result in completely blocked vision. The solution for this type of glare is polarized lenses.

Yet another common CL misconception is many people believe that they can’t wear contact lenses–this is most likely false. CLs are now available for wearers from an enormous demographic range. Teenagers and children are able to wear lenses subject to proper hygiene standards being maintained and lenses are now available for presbyopic and astigmatic patients who need toric or bifocal correction. Another common misconception is that CLs are not available for a particular prescription. This is most probably false. Modern lenses are available in an enormous range of prescriptions for a range of eye conditions. Contact lenses are available to correct myopia (short sightedness), hyperopia (long sightedness), presbyopia (for those over 40) and astigmatism. In addition to the enormous range of prescriptions cosmetic effects are also available for anyone who would like to change their eye color.

When light bounces off of shiny flat surfaces like roads, smooth water, or sand its waves reflect back into the eye vibrating in one direction–they have become horizontally polarized. This light also travels at a greater intensity which can cause glare and almost always produces an effect akin to peering through a sheer veil, resulting in a loss of clarity. The good news about horizontal polarized glare is that it can be eliminated by the use of polarized lenses. Since polarized light essentially consists of wavelengths that vibrate in one direction, the key to eliminating them is to filter them out while letting through unpolarized light–this is accomplished with the use of a polarizing filter. A polarizing filter is like a set of vertical blinds that are spaced minutely close together–light waves vibrating in the vertical plane can easily pass through this set of blinds, but waves vibrating in the horizontal plane cannot. Polarized lenses’ glare-fighting ability makes them an ideal choice for outdoor enthusiasts.

Another common contact lens question is that the care regimen for CLs is time consuming and complicated. This is false, the exact amount of care required varies depending upon depending on the specific type of lenses you wear. Extended wear lenses can be left in while you sleep and only need be changed at the intervals recommended by your practitioner. Daily disposable lenses should only be worn once and then discarded. Regular wear lenses primarily require only the use of one-bottle care solutions that reduce maintenance to a minimum.

A common question that is asked by many contact lens wearers is whether a contact lens can move and get lost behind the eye. This can never occur. A thin membrane calledthe conjunctiva forms a barrier between your eyeball and the eyelid making it impossible for the lens to move from the front part of your eye. Another common question concerning contact lenses is that they can cause eye infections. Some health problems can occur due to contact lens use but these are almost invariably due to poor hygiene or other care related issues such as wearing a lens for longer than the period recommended by your eye care professional. If you follow the professional advice you receive you are at an extremely low risk of suffering any adverse effects or infections due to CL use.

Some contact lens wearers who are early presbyopes (age 40+) are often well-served with monovision as an alternative to being fitted with bifocal contacts. With mnovision, you wear a contact lens on one eye to correct your ditance vision and a contact lens on your other eye to correct your near vision. The lens for distance vision is usually worn on your dominant eye. The induced imbalance between the eyes is most times minimal and, after a small adjustment period, often well tolerated. When distance or near vision is unacceptable, bifocal options need to be explored.

The best tint for sport sunglasses often depends on the environmental and lighting conditions you experience while participating in a particular sport. So, while this guide offers quick “tried-and-true” tint solutions recommended by many eyecare professionals, don’t be afraid to experiment with lens colors–sometimes the best tints for optimizing performance are a matter of personal preferenceDark amber, copper or brown tinted lenses block high amounts of blue light to heighten contrast and visual acuity. This can be useful to improve contrast on grass and against blue skies. Examples of sports in which these tints may help optimize performance include: baseball, cycling, fishing (especially in waters with grassy bottoms), golf, hunting, skiing, and/or water sports. Green tinted lenses heighten contrast (mildly) while preserving color balance. Examples of sports in which these tints may optimize performance include, baseball and/or golf. A gray tint reduces overall brightness while preserving 100 percent normal color recognition. Examples of sports in which these tints may help optimize performance include all outdoor sports in bright light conditions. Cornerstone Eye Associates Optical Studios have tint samples you can use to help you decide which color(s) are best for you. Try to evaluate the lenses in lighting conditions that match those you will experience most often during your sport. Moreover, if you participate in several sports or in a variety of lighting conditions, consider purchasing more than one pair of sport sunglasses, with different lens tints in each pair. Some sport sunglass frames have interchangeable lenses for a variety of lighting conditions.

As a continuation to the last blog, please also be aware that when it comes time for you to purchase some new lens care products, you may be tempted to buy a different brand because the cost is lower, but this is not always a wise idea in that what you may save money-wise may not be worth the risk of using a possibly inferior product and may result in infection. Although these products are safe and are FDA approved, they are not always the same as the brand name product. So, overall, it is better to stick with a name brand like the one your eye doctor recommends. Also, once again, if you have specific questions about your vision, eye care, contact lenses, or caring for contact lenses, it is always best to see your eye care professional.
