Anti Reflection Coating: Anti reflection coatings virtually eliminate the reflections from the back of your spectacle lenses, such as images of your own eye and eyelashes. These coatings also allow more light to reach your eyes, which increases contrast and clarity. Light reflections from the front of your lens are also significantly reduced. This also improves your appearance by allowing people to see your eyes and not the reflection on the lenses.

Aspheric lenses: In an aspheric design, the lenses have flatter curves; this means lenses do not "bulge" out of the frame as much as regular lenses. The side profile of aspheric lenses is thinner, which greatly enhances the appearance of finished eyewear. While high-index lenses primarily benefit people who are nearsighted, aspherics provide substantial benefits for both nearsighted and farsighted wearers.

Mirrored lenses: Mirrored lenses come in a variety of colors for specific visual needs and fashion applications. In contrast to antireflective coatings, which are very clear, mirror coatings (also called flash coatings) are bold statements of color.

Photochromatic lenses automatically darken in sunlight and lighten when indoors. They are a good option for people who don't like to switch from regular glasses to sunglasses. Photochromatic lenses are available in both plastic and glass. One important factor to remember is that photochromatic lenses do not darken much inside cars, since the windshield blocks many of the light rays that trigger color change.

Polarized lenses: Polarized lenses provide ultimate glare protection. Vision obscured by sun glare is one of the leading causes of automobile accidents. Sun glare is harshest when reflected off of a road pavement and vehicle hoods, making driving conditions dangerous. Reducing sun glare with polarized lenses means safer, more relaxed vision.

Scratch Resistant Coatings: Scratch resistant coatings increase the durability of plastic lenses. They should always be applied on both sides of the lens. Although no lens is scratch proof, scratch resistance coatings will help retard hairline scratches from abuse or improper cleaning.

UV Coatings: UV coatings protect your eyes by blocking the portion of UV light from the sun that can damage your eyes. Both glass and plastic lenses can be tinted to give protection from the sun at the same time as correcting your eyesight.

Single Vision Lenses: Single vision lenses have one power across the entire surface of the lens. These lenses correct myopia, hyperopia and astigmatism. Single vision lenses are available in all lens materials.

Bifocal Lenses: Bifocals offer far as well as near correction. The top part of the lens provides the distance refractive correction and the bottom segment provides the near refractive correction. These lenses correct presbyopia.

Trifocal Lenses: Trifocal lenses are made of three zones. The first is a distance zone, on top, for seeing distant objects. Then there is a mid-range zone for seeing intermediate objects and finally, there is a near zone for viewing close objects.

Progressive Lenses: Progressive lenses provide correction at all distances. They offer a continuous, gradual change in prescription strength from the lower (reading correction) to the upper (distance correction) portion of the lens.

Progressive occupational Lenses: Progressive occupational Lenses are unique lenses specifically designed for professional, computer users and hobbyists. They help to see clearly all the people and objects in your work place.

CR-39: Trade name of hard resin (plastic) lenses. CR-39 plastic is half the weight of Crown Glass(the same prescription) but scratches more easily than glass. It scratches x more easily than glass, but scratch-resistant coatings can minimize the damage

Plastic can be tinted to any color with uniform density. CR-39 plastic lenses characterized superior optical qualities.

HIGH INDEX: When a lenses refractive index is higher than standard glass (1.523) or CR-39 (1.498). High index plastic lenses come in 1.60, 1.66 and 1.71 indices. The higher the index, the thinner and lighter lenses become. High index should be considered for extremely high minus or high plus prescriptions. High index lenses are 25-40% lighter than CR-39.

Polycarbonate: Polycarbonate lenses offer two important features: they are lightweight, yet they are the most impact resistant lenses available. That makes them a good choice for children, teens, those whose occupation and hobbies require a lot of action.

Trivex: The newest lens material on the market. Trivex has superior optical features of CR-39 and impact resistance of polycarbonate.

Glass:Glass lenses can be twice as heavy as plastic and much more breakable. But, they provide the clearest possible vision and they're much more resistant to scratches, so people who have a tendency to scratch their lenses often pre fer glass
