Plastic lenses are one of the most popular. These are half the weight of glass lenses which make them more comfortable. Plastic also provides excellent optics and vision correction.
Polycarbonate lenses provide the highest level of impact protection. These lenses are very lightweight and considerably thinner than plastic. Polycarbonate lenses have a scratch resistant coating and UV protection. Due to their resistance to impact, these lenses are highly recommended for all children, safety glasses, and for any patient that has suffered a significant loss of vision or is blind in one eye.
A lightweight plastic material with a higher refractive index, meaning it has a greater ability to bend light resulting in a thinner lens. These lenses are most often recommended for patients with higher prescriptions to reduce thickness and weight of the lenses.
Glass lenses provide excellent optics and are scratch resistent but they can be heavy, thick, and dangerous if broken.
Single vision lenses correct for one field of vision, either for distance, intermediate (computer), or items up close (near vision).
Lined bifocals have two focal points, usually one lens for viewing distant objects and one lens for viewing close objects. There is a visible line across the middle of the lens that separates the two focal portions.
Lined trifocals have three focal points, usually one for distance, intermediate, and near vision. Typically the near and mid-range are included in an area that appears as a semi-circle toward the bottom with the very bottom being used for near vision. The intermediate range is toward the center of the lens. Nearly anything beyond an arm's length requires the wearer to use the topmost section of the trifocal.
Progressive lenses are line free so there is no image jump or distraction when your eyes move from one zone to another.
Scratch Resistant Coating
A hard coating that is applied to the front surface of the lens to reduce scratches and abrasions. The coating can also be applied to the back surface to reduce hairline scratches that are most often caused when rubbing the lens during cleaning.
Referred to as UV400 coating, this lens treatment absorbs UVA rays that have proven to accelerate aging of the crystalline lens, resulting in cataracts.
A photochromic lens that will darken in direct sunlight and lighten indoors. They are often requested by patients as a means to eliminate the purchase of prescription sunwear.
A multi-layered coating that dramatically reduces the glare associated with night driving. Cosmetically, these lenses appear thinner. Due to the elimination of glare and reflections from the front surface of the lens, visually lenses often "disappear" in the frames.
Polarized Sun Lenses
Polarized sun lenses are specialized eyewear designed to reduce glare from surfaces such as water, snow, and glass. These can be useful for certain sports and driving, helping participants see more clearly and avoid potential hazards.
