Popular Lenses Include:

 Aspheric--- Aspheric lenses, which provide a slimmer, more attractive profile and sharper peripheral vision than conventional eyeglass lenses.

Bifocal--- The most common type of multifocal. The lens is split into two sections. The upper part helps with distance vision. The lower half is for near vision. They’re usually prescribed for people over 40 who can’t focus well anymore. That’s due to presbyopia, an age-related change that affects your eye's lens.

Trifocals--- These are bifocals with a third section. It sits above the bifocal portion of the lens. You look through it to see objects within arm's reach, like a computer screen.

Hi-Index---High-index plastic lenses that are thinner and lighter than conventional lenses and provide better built-in protection against the sun's ultraviolet (UV) rays.

Photochromic---Photochromic lenses are clear lenses that provide 100 percent UV protection and automatically darken in response to sunlight to reduce the need for prescription sunglasses.

Polarized---Polarized lenses diminish glare from flat, reflective surfaces (like water) and also reduce eye fatigue.

Polycarbonate---Polycarbonate and Trivex lenses are thinner, lighter and up to 10 times more impact-resistant than regular plastic lenses, making them the perfect choice for safety glasses, sports eyewear and eyeglasses for children and active adults.

Progressive---These lenses have many advantages over bifocals and trifocals because they allow the wearer to focus at many different distances, not just two or three. Because they have no lines, progressive lenses allow a smooth, comfortable transition from one distance to another. They are a much better option for active, multitasking people.

Coatings You Can Add:

 Anti-Reflective---Anti-reflective coating is a popular add-on for lenses. AR (anti-reflective) coating can dramatically improve the look and comfort of your glasses by reducing distracting lens reflections that interfere with eye contact and make your lenses look thicker. AR-coated lenses also reduce glare and allow more light into your eyes for better night vision.
