Sunglasses facts dispel myths

SELECTING SUNGLASSES for the summer season
invalves much more than style considerations,

The smast buyer will focus on the comfott factor,
but will be smarter still by considering basic eye pro-
fection,

Recent health studies have underscored the damag-
ing effects of ultra-violet’ Hight on skin and. cyes.
Manufacturers have responded with new products
that provide UV protection. But, consumer
misconceptions abound.

Dr. Jack Weber, director of research and devel-
opment at a major eyewear manufacturer, has iden-
tified three of the most commonly held beliefs related
to sunglass selection.

Weber clarifies the factors involved in’ medically
correct eye protection by separating fact from fic-
tion. He also distinguishes eye protection from the
issue of comfort and style:

True or false?

1. The darker the sunglass lenses, the more they
will protect’ your eyes. This statement is incorrect.
The primary purpose for choosing a lighter or darker
sunglass lens is for eye comfort.

When protection is the issue, one must discuss
degrees of ultraviolet fight absorption, not darkness.
or lightness of sunglass lenses.

It’s entirely possible, for example, to have a pair
of sunglasses that boasts a very high level of UV
protection even though the lens may be very light.
UV inhibitors protect your eyes; the lightness or
darkness of sunglass lenses do not.

2. If you can see your eyes, your sunglasses are not
dark enough. This statement is false. {¢ is most im-
portant to put this particular myth out to pasture —

immediately, Unless dark-lens sunglasses have UV
protection, Urey are downright dangerous.

A person may mistakenly buy sunglasses with very
dark lenses but without any UV protection, believing
that dark leases alone provide sufficient: protection.
They don't!

In fact, according to Weber, ‘‘Coprotected dark
lenses are a double disaster. Dark lenses send a
message to the pupil of the eye to admit more light;
in response, the pupil enlarges to do just that!

Now noc only is the unfiltered light absorbed by
the eye, in the long run, it could well be a source of
injury.

3. Whether vour eves are lieht or dark, the amount
of protection they need is the same. This is another
variation of the protection vs. comfort distinction.
For protection, sunglasses must hive UV inhibitors,
whether your eyes are light or dark. For comfort,
light cyes are going to feel better in darker lenses.
Dark eyes will do fine in medium to fight fenses.

Dark eyes have more pigment in them, which helps
to absorb brightness. Light eyes have less pigment
and are more sensitive to light.

Thus, lightness or darkness of your natural eye
color does affect your choice of fighter or darker

- sunglass lenses.

The protection rule is to look for broad spectrum,
UVA and UVB protective sunglasses.

Finally, sunglasses that screen UVA and UVB rays
provide the best-known health protection for eyes.
And since these rays are present on sunny and. cloudy
days, ali year round, Weber suggests wearing

sunglasses whenever you're out of doors.
