Different Lens Types:
Single Vision Lenses - These are pretty much your standard prescriptions. It is your most basic type of lens where your prescription is added to the whole lens. This allows for patients to see at all distances.
Bifocal Lenses: These lenses are split into 2 parts. The upper part is used for distance while the bottom part is used for being able to see up close.
Progressive Lenses: These lenses are basically bifocal lenses with no line between the upper and lower prescriptions. They are also called "No-line Bifocals". Some patients prefer this option because they look like single vision lenses.
Transition Lenses: These special lenses darken or lighten depending on how much sunlight hits the lens. They are also called "Photocromic Lenses". 'Photo' meaning light, and 'chroma' meaning color.
Polarized Lenses: Polarized lenses reduce reflections and eliminate glare. They improve visual comfort and clarity as well.
High Index Lenses: High Index lenses are lighter and thinner than other lens materials. These are more suitable for customers with high prescriptions, generally +/-3.00 or more.
