Protecting Eyes From The Sun...
In India, every day - whether it is sunny or cloudy, and despite the
season - we are exposed to ultraviolet (UV) radiation from the sun.
Most of the time we don't even realize it, considering UV rays are
invisible to the eye. However, just as sun can damage your skin
(burning, wrinkling, skin cancer and premature aging) it can be just as
nasty on your eyes.
Unprotected exposure over long periods of time can, and often does,
damage the eye. This exposure can greatly increase the chances of
cataracts, age-related macular degeneration and glaucoma. These
conditions can seriously impair vision and are usually impossible to
Fortunately, vision damage can be prevented by shading your eyes from UV
rays. Wearing sunglasses with 100 percent UV protection can
significantly reduce the risk of vision problems caused by sunlight.
Wrap-around frames and large lenses can also help to provide an extra
measure of protection.
The sun's glare can also pose a risk to ones health, severely affecting
visual acuity and comfort. There are four levels of glare:
- Distracting glare caused by lens reflections. This is usually a minor annoyance, but can also result in eye fatigue.
- Discomforting glare caused by bright lights. This type of glare also
results in eye fatigue, often as a result of constant squinting.
- Disabling glare caused by excessive, intense light, which blocks vision.
- Blinding glare caused by reflections from smooth surfaces, such as
roads, water or snow. Blinding glare can be dangerous as it blocks
vision in critical situations (i.e. driving or skiing).
Luckily, there are multiple ways to reduce glare, including anti-reflective lenses, fixed-tint lenses or polarized lenses.
Constant advances in technology and style options can give you a
competitive edge that will help you to see better and look great. There
has never been a better time to build an eyewear wardrobe that suits
your personality and lifestyle, and enables you to always be on top of
your game - whether at work or at play.
Consider the following options when selecting the perfect sunwear lenses for your lifestyle:
- Photochromic Lenses: These changeable lenses automatically darken
and lighten to provide the right level of protection and comfort over a
wide range of light conditions.
- Polarized Lenses: Polarized lenses work exceptionally well to filter
out reflected glare from shiny surfaces like water, pavement and
dashboards. They improve contrast and visibility while reducing squint
- Impact Resistant Lenses: All sunglasses which meet International
Standards have impact resistant lenses. Until recently the only lens
material recommended for high impact or competitive sport use was
polycarbonate. Now there are new high strength lens materials, including
polyurethane, which bring new performance options.
- Tints: Certain tints that control the amount and type of light that
reaches the eye can improve performance by enhancing contrast, colors
and visibility. Click here for popular tint options.
- Anti-reflective Lenses: These lenses dramatically reduce distracting
reflections, improving contrast, visual acuity and comfort in difficult
There are a wide variety of frame materials which can impact
performance, durability and comfort such as titanium, memory metals,
stainless steel and numerous high-tech options in plastic. Style
features such as non-slip bridges, gripper temples, spring hinges,
shields, wraps and venting systems add value and comfort and pump up
your performance at the same time. Sun clips and sunwear that fits
directly over prescription eyewear are also available to meet specific
needs. Talk to your eyecare professional for recommendations on sunwear
that fits your lifestyle.
Aside from the important function of guarding the eyes from sun-related
eye diseases and harmful glare, sunwear can also provide a variety of
comfort and vision benefits, such as:
- Protecting the eyes from wind, dust and pollen
- Helping to comfort dry eyes
- Preserving good night vision (when worn during the day and not at night)
- Enhancing contrast
- Reducing tearing and squinting
And don't forget about the kids! You wouldn't send your children outdoors without sunscreen, so don't send them without sunglasses either.
Children's developing eyes let in more UV rays than adults' and since
children tend to spend a majority of their time outdoors, sunglasses
with the most impact-resistant lenses are a must for all kids.
