Single Vision Lenses
Single vision prescription lenses offer vision correction for one field of sight - near or far. They do not correct multiple fields of vision, like progressive lenses do.

Reading Lenses
Reading lenses are technically single vision lenses, correcting only one field of sight - near. They provide simple magnification and a prescription is generally not necessary.

Progressive Lenses
Progressive prescription lenses offer vision correction for multiple fields of sight, near, far and intermediate, eliminating the need for multiple pairs of glasses.

Progressive lenses are not available online but are available in every SEE store.

This image shows the same strong prescription in both frames - one is Polycarbonate and one is 1.74 High Index. Can you see the difference in thickness?

Forgive us while we get technical with you: The "lens index" is the number that determines how thick or thin your prescription eyeglass lenses are. The higher the index number, the thinner the lenses. High index lenses are best for strong prescriptions. They are even thinner and lighter weight than polycarbonate lenses.

1.67 High Index Lenses
These lenses are best for prescriptions +/- 3.00D or stronger.

1.74 High Index Lenses
These lenses are the thinnest lenses available. They are best for prescriptions +/- 6.00D or stronger.

When added to your lenses, anti-reflective (AR) coating provides sharper, crisper vision by blocking glare from screens and other light sources both during the day and at night. Our AR lenses have seven layers of anti-reflective coating on each side of the lens. We also include one hydrophobic (anti-water) layer and one oleophobic (anti-oil) layer for easier cleaning.

Lenses with AR coating don't just function better, they actually enhance the look of your eyewear by eliminating virtually all reflections.

Transitions® Light Intelligent Lenses™ are fully clear indoors and become darker outdoors, reducing eye strain and glare. These lenses block 100% UV and help filter harmful blue light.

No need for swapping glasses and sunglasses! Transitions® lenses adapt seamlessly to any lighting for optimum vision and comfort.

We offer five different Transitions® lens colors: Gray, Brown, Amethyst, Emerald, and Sapphire. Not all colors are available for all lens types.
