When it comes to customizing eyeglasses, there are many
eyeglass lens materials that can give you the functionality and fashion you
want. Although materials don’t have an impact on the corrective power of the
lens, different materials do offer specific lifestyle benefits. Take a look at
this eyeglass lens overview to learn more about the most popular and widespread
lens materials, then speak with your certified eye care specialist to
choose a lens that’s right for you. Taking the time to locate appropriate
lenses will ensure your new eyeglasses are comfortable, stylish, and functional.
Hi-index
lenses. Using a unique method of refraction,
hi-index lenses provide vision correction using less material, resulting
in a thinner lens. These smaller lenses are perfect for patients with high
prescriptions. Thinner lenses also mean your glasses will be lighter and
more comfortable. When looking at hi-index lenses, you will see numbers
such as 1.50 or 1.67, which correspond to the thickness of the lens (higher
numbers are thinner).
Polycarbonate
lenses. One of the most popular lens
materials, polycarbonate lenses are made from a “hi-index plastic” that is
sturdier and more durable than regular plastic lenses. Polycarbonate
lenses offer a lightweight construction that is comfortable to wear. They
also have the added benefit of built-in UV protection, which makes them
great for anybody who spends time outdoors.
Trivex
lenses. Trivex is a newer material which
shares many of the characteristics of polycarbonate lenses. The one major
advantage of Trivex lenses are their unique optics, which provide clearer
and crisper vision. Trivex is just as durable as standard polycarbonate
lenses, but more rigid. This makes them perfect for children’s
eyeglasses, safety lenses, and sport vision.
Photochromatic
lenses. Photochromatic lenses are a convenient
option that shift to a dark tint in sunlight and turn translucent when
indoors. The main benefit of these lenses is that they eliminate the need
to carry around two pairs of prescription glasses. The dark tint appears
when the lenses are exposed to UV rays. Keep in mind that these lenses may
not work well behind the windshield of your car, which blocks out most
ultraviolet rays.
Anti-reflective
coatings and lenses. Anti-reflective coatings can be
applied to any type of eyeglass lens. This helpful treatment is an effective
way to remove both internal and external glare, improving the quality of
vision correction. Anti-reflective coating is also useful at nighttime, as
it does a good job removing distracting glares and halos from nearby light
sources. Just about everybody can benefit from this special coating, but
those with high prescriptions will find it especially useful.
Ultraviolet
coatings and lenses. Keeping your eyes shielded from
harmful UV rays is an important way to keep them healthy. By purchasing
UV-resistant lenses or having your lenses coated with UV-treatment, you
can block out harmful rays that can cause cataracts and macular
degeneration.
These are just some of the many eyeglass lens materials
and coatings you can use to customize your eyeglasses. If you’re looking for
more information about lenses that fit your lifestyle, don’t hesitate to
contact your local eye care provider for more information. A certified eye care
specialist can tell you exactly what type of lenses will work best for you.
