Lenses:
Perhaps the most important
aspect of effective sports
sunwear is the optical
quality and visual
enhancement of the lenses.
Many lens colors that are
particularly effective in
certain situations (such as
brown, green, gray, yellow,
orange, etc.) are now
available.
Polycarbonate lenses are
also extremely popular, as
they are super strong and
impact-resistant, a benefit
that is particularly
appealing to many people
involved in sports.
Polarized lenses are also in
demand, because they reduce
glare produced on flat
surfaces such as water or a
field of snow. There is,
however, some debate as to
polarized lenses'
effectiveness when it comes
to sports that require
contrast definition like
downhill and mogul skiing.
Glass lenses are used
occasionally in sports
eyewear (like in sunglasses
for golfing) because of
their great optical quality,
but many people involved in
more extreme sports shy away
from them because of the
potential for shattering
upon impact.
