STANDARD SUNGLASSES
If you spend a lot of time around water, we recommend you wear protective sunglasses. It
has been found that excessive amount of ultraviolet light can increase your risk of
cataracts and retinal damage. Quality
sunglasses have ground lenses (not thin plastic) which are free of distortions and
imperfections. Thin plastic lenses usually contain lens distortions and can actually
reduce your visual acuity (the ability to see things clearly). In addition, quality
sunglasses filter about 80% of the visible light spectrum, and filter out all the
ultraviolet light rays and infrared light rays. The best tint colors are gray, green and
brown. These colors filter more evenly across the visible light spectrum.
POLARIZED SUNGLASSES
A polarized lens acts like a filter or lattice which allows the useful light traveling
from an object to reach the eye, while blocking all the glare caused by the scattered
light traveling in many different random directions. Therefore, Polarized Sunglasses
combine the advantages of Standard Sunglasses with a polarized lens. These lenses are
particularly effective around water.
SPECIAL ITEMS
Many people lose their glasses in lakes and streams. Frame straps are available which
keeps the frame from falling off your face. Also, floatation devices which slip over the
temples (earpieces) of your glasses are available. These make your glasses float until you
can retrieve them.
CONTACT LENS WEARERS
It is recommended that people who wear contact lenses either remove their lenses for
swimming, or wear a Non-prescription Swimming Goggle. Exposing contact lenses to
water increases the risk of eye infections. These Non-Prescription Swimming Goggles are
also available with tints. Quality sunglasses should be worn when you have your contacts
on and are around water.
