LENS MATERIALS & BENEFITS

PLASTIC: another term for this material is CR-39. Plastic is the standard material used for eyeglasses in the United States.

POLYCARBONATE: light weight and very durable. This is one of the safest and most impact resistant lens available-- used for all children's eyeglasses.

MID-INDEX: a thin alternative to plastic especially used for stronger far-sighted prescriptions.

HI-INDEX: a thinner alternative to plastic used for stronger near-sighted prescriptions.

HYPER-INDEX: our thinnest alternative to plastic used for stronger near and far-sighted prescriptions.
 

LENS TYPES

SINGLE VISION: allows for one focal point of vision, distance or near.

BI-FOCAL: allows for two focal points of vision, distance and near.

TRI-FOCAL: allows for three focal points of vision, distance, intermediate, and near.

PROGRESSIVE ADDITION LENSES: allows for all focal points to have clear vision. Though you may have tried a progressive lens before and failed, today there are over 100 different lens designs. We assess your needs to find the right lens for your lifestyle and activities without compromising the quality. Only the latest in lens design/technology are used to give you optimal vision.
 

LENS TREATMENTS AND COATINGS

ANTI-REFLECTION: blocks out unwanted glare and gives you cleaner crisper vision allowing over 99 percent light transmittance through your lenses. Lenses without anti-reflection only allows 89 to 92 percent light transmittance depending on the lens material.

TRANSITIONS: are variable tint lenses. While you are out in the sun light they turn dark gray or brown and remain virtually clear indoors. Transitions are now on their fourth generation.

POLARIZED: lenses allow you optimal sun protection. Being out on Lake Tahoe soaking up the sun, fishing, or driving down 101 or 880 the horizontal sun rays can seem blinding. Polarized lenses filter out all other rays allowing your vision to remain clean and crisp. Please come in for a demonstration and you will see for yourself.

UV COATING: protects your eyes against the harmful UV rays A and B. All higher index lens materials inherently have UV protection.

TINT: colors range from any red, blue, or yellow with any imaginable color and shade in between for the perfect sunglasses or a fashion forward look.

SCRATCH COATING: gives the lenses more durability against normal wear and tear.
