Types of Eyeglasses

Glasses aren't a one-size-fits-all type of gear. It isn't just about the prescription and eyeglass frames, either. Several types of glasses exist including monofocal, bifocal and trifocal lenses. Not to mention, different varieties of lenses are available that are scratch resistant and even reduce glare. Knowing the different types of eyeglasses will make your appointment with us less stressful and make you feel more confident with your decision.

Monofocal, Bifocal, and Trifocal, Oh My!

Monofocal have lenses with only one distance. The distance may be near, intermediate or far away. Bifocals have two different distances in one lens. You'll look upward to see far away, and you'll look down to see close up. We evaluate your visual acuity during an eyeglasses examination, so both portions of your bifocals are customized to your distance and up close vision range. Trifocals and multifocal lenses have more than two distances. They have an up close, intermediate and far away vision. Your intermediate vision is what you see at an arm's length away from you such as a computer screen.

Materials of Eyeglasses

Despite their name, eyeglasses aren't always comprised of glass anymore. Technological advancements allow you to see the same, if not greater, visual clarity using lenses that are less likely to break. Polycarbonate is one material that is impact resistant, making them an excellent option for children or those who play sports.

Trivex is another option, which is a newer plastic that's similar to polycarbonate lenses. They're thin, impact-resistant and lightweight. They actually correct vision better for some people.

High-index plastic is the ideal option for people with strong prescriptions. These lenses don't have the thickness that traditional lenses have. They are lighter and thinner.

Aspheric lenses are thinner and flatter and have various degrees of curvature in one lens. Therefore, you're able to use a much larger surface of the lens.

Photochromic lenses change color based on the light in the room. Because of their tint, you might be able to use one pair of glasses instead of having to have a second pair of prescription sunglasses. These glasses may be comprised of plastic or glass. You may also opt for prescription sunglasses in addition to your regular eyeglass prescription. If you ski or participate in water sports, you may want to get polarized sunglasses, which reduce glare.

Eyeglasses Prescription

We offer glasses for nearsightedness, farsightedness and those who need a prescription for both. We even have glasses specifically designed for patients who have a refractive error such as astigmatism.
