Today’s Different Lenses for Eyeglasses and the Flexibility They Offer

eye glasses Shawnee OpticalJust like computers and cell phones, eyeglass lenses have evolved over time and continue to do so.  As the name implies, eyeglass lenses were once exclusively made out of glass. Now, lenses can be made from glass as well as many different types of specially formulated plastics that are matched to the vision correction needs and the choices of the person who will be wearing the eyeglasses.

Today, eyeglass lenses are thinner and more lightweight than ever. When you factor in the different coatings that can be applied to lenses, they can also be resistant to scratches, dust, smudges and fogging.  Modern-day lens options also offer more flexibility and compatibility when it comes to selecting a pair of frames that provide the appearance and functionality desired.

Here’s an overview of the types of eyeglass lenses offered today:

High Index Plastic Lenses

If you wear thick “coke bottle” lenses, high index plastic lenses may be a welcome alternative. Specifically designed for people who require strong eyeglass prescriptions, these lenses offer a much thinner, lighter and attractive option compared to the traditionally thick lenses.

Polycarbonate Lenses

Polycarbonate lenses are an impact-resistant type of plastic lens. They are a good choice for people who work or play in environments in which their eyeglass lenses may be easily dropped or scratched.  Polycarbonate lenses also provide ultraviolet protection.

Trivex Lenses

Similar to polycarbonate lenses, Trivex lenses are made from a special type of plastic that is thin, lightweight and impact-resistant.  Trivex lenses provide better vision correction than polycarbonate lenses for some people.

Photochromic Lenses

Photochromic lenses can be made from either plastic or glass. When exposed to sunlight, this type of eyeglass lens changes from clear to tinted eliminating the need for prescription sunglasses.

Polarized Lenses

Polarized lenses are commonly found in sunglasses. These types of lenses reduce glare and the light reflected from water, snow or a flat surface.

Regardless of the type of lens, the purpose remains the same. They all are made to focus light correctly on the retina in order to provide clear vision.
