Selecting the right eyeglasses involves much more than just nice looking eyeglass frames.
Today there are a tremendous amount of options for eyeglasses lenses, which can really
improve the way you look and see through your glasses, as well as how long they last.
Here are a few of the most popular glass lenses Dr. Ronald Cauchard offers:
Polycarbonate Lenses or Trivex Lenses:
If you are looking for glasses lenses that are lightweight and durable, Polycarbonate lenses
or Trivex lenses are a good option. Great for children’s eyeglasses, sunglasses, safety
glasses and sports eyewear, these lenses are thinner and lighter than regular plastic lenses,
but 10 times more impact resistant. They also provide 100% UV protection.
These eyeglass lenses are the perfect solution for those who are frequently on the go and
don’t like switching between eyeglasses and sunglasses. Photochromic lenses, such as
transition lenses, are sensitive to light – they are clear indoors and darken when exposed
to sunlight. Photochromic lenses are also great for children’s eyewear, offering hassle-
free UV protection for kids who spend a lot of time outdoors.
High Index and Aspheric Lenses:
If you have a particularly high prescription, but still want a thin, lighter lens, aspheric
or high index lenses are for you. Aspheric and high index lenses are created with a
slimmer curvature which improves the appearance of the eyeglasses by making the eye
appear less magnified and the lens bulge less from the frame. This also increases the
options for someone with strong prescription eyeglasses to wear a larger selection of eye
glass frames without the concern of lenses being too thick.
Anti-Reflective Coatings (AR) or Anti –Glare Coatings:
Anti-reflective and anti-glare coatings can be added to most lens materials. These
coatings improve the performance as well as the appearance of your glasses, by blocking
reflected light and reducing glare in both directions (both the glare you see reflecting off
objects in your view such as TV screens and the reflection others see on your eyeglass
lens). AR coatings are one of the most popular add-ons for lenses, since they significantly
reduce glare and eye fatigue. If you spend a lot of time on your computer, consider
computer glasses with an anti-glare coating.
Scratch-resistant coating (SRC):
Scratch resistant coatings create a harder surface on the eyeglass lens, making it more resistant to scratching. Many lenses, particularly polycarbonate and high-index lenses, are made scratch-resistant, so you should check with your optician to see if the treatment is necessary. SRC is recommended for children’s eyewear and for those who work or play in environments that pose a risk to the lenses.
Prolonged exposure to UV light, even in the winter months, is known to cause damage
to the eyes including cataracts and retinal damage. Check that your eye glass lenses have
100% UV protection. If they don’t, UV treatment for lenses is an invisible coating that
will give you added protection from the sun.
When purchasing your next pair of eyeglasses, speak to our eye doctor about the options
for eyeglass lenses. While you want to select a frame that looks and feels great, don’t
forget that seeing great is what eyeglasses are really made for.
