All About Lenses FAQs

Choosing the right eyeglass lenses is just as important as choosing your frames. The right lenses will ensure you have optimal vision. The following FAQs from Indigo Vision Center in Georgetown provide greater insight into eyeglass lens types, coatings, and materials to help you make the best choice.


What materials are eyeglass lenses made of?

Eyeglass lenses are made of diverse materials to suit your prescription and lifestyle.

  • Glass lenses offer great optics, but break easily, making them a poor choice for those who live an active lifestyle.
  • Standard plastic lenses are affordable, durable, lightweight, and provide good optics, making them a good choice for children and active adults.
  • Polycarbonate lenses are more lightweight and resilient than standard plastic lenses and are commonly used for children’s eyewear, sports eyewear, and safety glasses.
  • Trivex lenses are known for being lightweight, resilient, and providing great optics.

What are multifocal lenses?

Multifocal lenses help correct multiple prescriptions. Bifocals, trifocals, and progressive lenses are examples of multifocal lenses. If you need glasses that correct both near and far vision, our optometry specialists may recommend multifocal lenses. Bifocal lenses are split into two sections to improve your near and far vision. Trifocal lenses are split into three sections. Progressive lenses have no visible division but provide distance vision on top and gradually progress to meeting your near vision needs toward the bottom.

What type of lens reduces glare?

Polarized lenses help reduce glare from the sun when you are outdoors. They also reduce glare from the water when you are out on the lake or from snow when skiing or snowboarding. If you participate in water or winter sports, polarized lenses can improve your sports performance. In addition to enhancing sports performance, polarized lenses provide UV protection from the sun. You can find polarized lenses in our optical shop.

What type of lens turns dark when exposed to the sun?

Photochromic lenses darken when exposed to sunlight, enabling you to use your prescription glasses as sunglasses. As sunglasses, photochromic transitions also block UV light to protect your eyes.

What lens can I use to reduce glare when working on my computer?

Blue light lenses and anti-reflective lenses can help reduce glare when working on your computer. Blue light lenses also protect your eyes from blue light emissions from your digital devices.

What types of coatings can be put on eyeglasses?

Some of the most common coatings for prescription glasses are anti-reflective coating to reduce glare, scratch-resistant coating, tint to see better in the sun, and nontransparent mirror coatings to hide your eyes.
