OPHTHALMIC LENSES

Single Vision: Farsightedness, nearsightedness, and astigmatism are corrected by using a single vision lens. This lens is the most common to use in glasses to correct simple visual defects. This lens has one field of vision.

Bifocal: This lens has 2 fields of vision. Bifocals are commonly prescribed to patients with presbyopia (age-related loss of the eyes’ ability to focus actively on nearby objects) who also require a correction for myopia (distance is blurry), hyperopia (near is blurry), and/or astigmatism (common imperfection in the eye’s curvature).

Trifocal: Lens that has 3 fields of vision. Near, far, and intermediate vision. The lens has visible lines to separate the areas.

Progressive: Offers a smooth transition on the lens to go from near, far, and intermediate vision. The progression of correction eases eye strain by providing the most natural vision correction. Also known as no-line glasses or no-line bifocals.

Eyezen: Enhances the single vision lens to protect your eyes from harmful blue light that projects from digital devices. Reduces eye strain and helps to sharpen vision with digital device use. They are clear in color and appearance.

We offer Varilux® progressive lenses, click on this video to find out what makes Varilux® different from the rest.

Explore how Eyezen+™ lenses help protect your eyes from digital strain and discomfort. A lot of eyecare professionals stand behind this lens enhancement to your single vision lens.

MATERIALS

CR-39: The most common material lenses are constructed from. CR-39 (Columbia Resin #39) is a plastic polymer eyeglass material.

High Index: Lens material that reduces lens thickness, making these lenses more comfortable and better looking by minimizing the size of visible lens edges for nearsighted wearers and reducing the magnified “bug eye” appearance associated with farsighted wearers.

Polycarbonate: Light, strong, impact resistant lens material with UV light protection. Great for patients who are athletes, work in hazardous work environments, and kids: all for the protection. For glasses that are rimless since it will resist chipping or cracking if they are accidentally dropped. Also, for those patients with sight in only one eye.

Trivex: Another great thin, light weight, strong, impact resistant lens material. Developed in 2001 by PPG Industries right here in Pittsburgh! Offers crystal clear optical clarity because the lens has less internal stress so they can be made super thin without cracking. Also offers full UV protection inside the lens.

Glass: The original classic lens. Offers superior optical clarity, however glass lenses can be heavy and not offer much protection if impacted or dropped. No UV protection, nor can it be added into the glass.

OPTIONS

Scratch coating: A treatment used to coat the lens to protect and resist scratching. This is great to have on all glasses.

UV Protection: An added protective coating for repelling UV light.

Anti Reflective: Assists in keeping the lenses clear when light is projecting into the lens. Great for night time driving to help keep glare out of your line of vision and helps to reduce eye strain on computer, television and cell phone screens.

Transitions: Lenses that lighten and darken when exposed to UV light. They help to reduce eye strain when inside and outside, assist with glare, and block UV light. We offer Transitions Signature and XTRActive lenses here in our office. XTRActive offers a variety of colors and mirrored lenses to match your liking.

Polarized: An invisible filter built into sunglass lenses to enhance the visual clarity and colors, protect your eyes against UV rays, and reduce glare. They eliminate the amount of reflective light that enters the eye. Great for patients who may be outside a lot of the time, boating, or playing sports.

ExperioUV: A step beyond polarized lenses, the ExperioUV adds extra benefits to your sunglass lenses. Offering, a hard coat scratch resistant layer, polarized film, high surface density and anti-particulate layer which repels smudges, oil, and water so the lens is easy to clean. Enhances the visual clarity and comes in a variety of colors as well.

This video explains in detail what benefits you’ll receive from the Crizal® coating. It is an advanced scratch resistant, anti-reflective, water, smudge, and dust repellant.

Transition lenses are great for kids and adults!
