Sunglasses for Function and Fashion

Sunglasses for Function and Fashion

Sunglasses are more than a fashion statement!  They protect our eyes from the harmful effects of the sun!

WHY DO PEOPLE NEED SUNGLASSES? People need sunglasses for:

* Ultraviolet (UV) radiation protection – The sun’s UV radiation can cause cataracts; benign growths on the eye’s surface; cancer of the eyelid and skin around the eye; and many other conditions.  Wide-brimmed hats and caps do not adequately protect the eyes, only blocking about 50% of UV radiation.

* Blue-light protection – Long term exposure to the blue and violet portion of the sun’s rays has ben implicated as a risk factor for macular degeneration.

* Comfortable vision – The sun’s brightness and glare interferes with comfortable vision and the ability to see clearly by causing squinting and watering of the eyes.

* Dark adaption – Spending as littles as 2 or 3 hours in bright sunlight can hamper the eyes’ ability to adapt quickly to nighttime or indoor light levels.


NOT ALL SUNGLASSES ARE THE SAME!!  What to look for in sunglasses:

* Lenses that block 99-100% of both UV-A and UV-B radiation

* Lenses that screen out 75-90% of visible light

* Polycarbonate lenses are a must for sunglasses worn for potentially hazardous work or sporting activities.  These lenses provide the greatest available impact protection.

* Wraparound frames provide added UV protection for bright environments.


Other Important Sunglasses Facts

** Sunglasses are necessary for ALL ages! Most UV radiation exposure occurs during childhood.

** Lens color or darkness is no gauge of the level of UV protection.

** Price is no gauge of UV protection or of lens quality.

** Polarized lenses combat reflected glare.  They provide added comfort and better vision for driving or boating.  However, polarization may not be the best choice for all activities.

** People should not only wear sunglasses when they are outdoors working participating in sports, or taking a walk, but also while driving in their car or running errands.
