Everyone’s eyes are different, so we offer various lens options to fit the unique needs of each individual’s eyes.
Single-vision Lens: Having the same prescription across the entire lens.
Bi-focal/Tri-focal Lens: Having two or three different prescriptions in the lens, usually differentiated by a visible horizontal line, where the top portion is used for seeing distances, the middle for intermediate, and the bottom portion is used for near vision, such as reading.
Enhanced Multifocal Lens (atLast!): A composite lens technology that provides a spacious intermediate vision field
Progressive Lens: A bifocal or trifocal lens that does not show the line(s) between distance, intermediate and near prescriptions.
Transitions Lenses: With Transitions lenses, the lenses become darker or lighter when adjusting to natural light. Transitions lenses are clear when indoors and at night, but automatically adjust their level of tint to changing light conditions outdoors. https://new.transitions.com/en-us/
Anti-reflective (Crizal): These virtually invisible lenses are extremely durable, scratch resistant, and easy to clean. State-of-the-art, no-glare properties are combined with double-sided scratch resistance and a finish that repels water. Crizal lenses eliminate reflections that cause eyestrain and fatigue, especially from fluorescent lighting and computer screens. They resist dirt and smudges, so you do not have to clean them as often.https://www.essilorusa.com/products/crizal
Scratch-resistant (see Crizal, above)
Tint: A dye that is applied to the lens and remains constant at all times. Lighter, fashion tints are used primarily for cosmetic purposes. Darker tints allow the wearer to use the lenses as sunglasses. A tint can be solid, when the entire lens is the same color, or gradient, which is a gradual fade from dark to light, usually fading from the top down.
Polycarbonate: Plastic that is very impact-resistant. Often used for children’s glasses.
High-index Lens: Type of lens with a higher index of refraction, meaning that light travels faster through the lens to reach the eye than with traditional glass or plastic. It is denser, so the same amount of visual correction occurs with less material (whether glass or plastic) — so the lens can be thinner.
Blutech Lens: This new lens technology is designed to minimize your exposure to harmful blue light that is commonly emitted by our electronics and light sources. This leads to enhanced vision, contrast and overall improved eye health. Learn more here: Macular Health Initiative.
