Shades
Here’s a dark thought:
Wearing sunglasses that
don’t have UV-protection
can actually be worse for
your eyes than not wearing
them at all. Pupils dilate
behind dark lenses, which
leaves the retina more
vulnerable to the sun’s rays
and possibly increases
cataract risk. The color of
the lenses has nothing to
do with UV protection—the
coating that screens out
these rays is clear—so
buying a darker tint won’t
guarantee that you’re
shielded. Read the label
and make sure your shades
meet these standards.
They block 99
percent of both UVA
and UVB rays.
They’re fitted with
polarized lenses—
these cut glare and
improve vision
when you’re driving.
They have wraparound
styling to block rays
from the sides.
