Single vision correction is designed to help people who require correction of farsightedness, nearsightedness, or astigmatism. These eyeglasses have just a single optical prescription correction and distributes focus evenly over the entire surface area of the lens.

-Standard: Spherical, conventional design
-HD Digital: Aspheric, flatter, more precise and digitally surfaced lens design
-Shamir Relax: an anti-fatigue lens for single vision wearers. Click to learn more.

Provides the optimal balance between:
-distance (far) vision and reading (near) vision
-distance (far) vision and computer vision
-computer vision and reading (near) vision

-FT-28 is a standard lined bifocal with a window width of 28 mm.
-Shamir Duo is a blended bifocal; ideal if you do not like the visible line in a standard bifocal.

Trifocal lenses are similar to bifocals, with the exception of having two focal areas separated by a third middle area with intermediate focus correction. This area is to correct vision roughly at arms’ length, e.g. computer range. This lens type has two segment lines, dividing the three different correcting segments.

-7x28 trifocal has a window width of 28mm, 7mm height for the intermediate range
-8x35 trifocal has a window width of 35mm, 8mm height for the intermediate range

Provides a smooth transition from distance correction, intermediate correction, to near correction, eliminating segment lines and allowing clear vision at all distances. There are many different designs of progressive lenses that range from conventional (basic) lenses to digital free-form lenses (widest peripheral range)

Best: Shamir Intelligence (widest peripheral range) or Shamir Autograph III
Better: Shamir Autograph II or Varilux Comfort W2+
Good: Shamir Spectrum (narrow window, not recommended for computer/intermediate use)

Do you need lenses particularly for work because you're on the computer all day long?

We recommend computer and workspace lenses if you find yourself needing more intermediate (computer) range than your normal progressives allow.

Shamir Computer (near and intermediate)
Shamir Workspace (intermediate and distance)

eyeRelax HD XN: Maximized for near and intermediate use with limited distance vision. Sitting down to read a book, do some office work—basically getting down to business? This lens is perfect for you.


eyeRelax HD XM: Maximized for most distance possible. This is still a task lens so don’t expect to shoot a perfect game in bowling league wearing these. XM is great for people that are up and down or need to be able to look across the room and see customers or coworkers.

eyeRelax HD XB: Balanced. This is the default version of the eyeRelax lenses and provides the a mix of near and distance vision without compromising too much of the intermediate width provided by the XN.

Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain and makes your eyeglasses look more attractive.

AR coating virtually eliminates reflections from the front and back surfaces of your lenses. More light passes through your lenses to optimize visual acuity with fewer distractions (especially at night), and the lenses look nearly invisible.

Best Overall: Crizal Sapphire or Rock
Best Blue Light: Crizal Prevencia
Good: In-House AR, In-House Blue AR

Transitions or Transitions XTRActive are great if you want an all in one set of eyeglasses. The lenses change to a darker tinted lens color as it gets exposed to the UV light. The lenses help to reduce eye strain and eye fatigue caused by bright lights when outdoors. Transitions are an ideal solution if you're looking for a great blue light blocker.

Polarized: An additional layer added to the lens to block out glare from horizontal surfaces to reduce brightness and discomfort.

Solid Tint: Color varies depending on personal preferences. Darker tints are used as sunglasses, while lighter tints are used for fashion. Tints are used to reduce brightness and discomfort.

Gradient Tint: Color is darker on the top and faded to a lighter color on the bottom. This design is ideal for reading outdoors, and/or leaving the sunglasses on for days that are not as bright. The density of the darkest part of the lens and the color can be varied to accommodate for each individual’s preference.

Mirror coatings decrease light transmission thereby minimizing certain harmful wavelengths from reaching the eyes. They optimize the usable light that passes through the lens for specific light conditions helping guard against harmful high energy visible light and reducing eye strain and fatigue. They enhance function and fashion in both sun and sports eyewear, giving advanced sun protection and great cosmetic appeal.

Blue Filter Technology: Artificial blue light from screens and energy-efficient lighting disrupts your biological clock and causes digital eye strain; negatively impacting sleep, health, and productivity. Adding this feature reduces your exposure to blue light.

Backside Anti-Reflective Coating: Reduces light that bounces or reflects off the backside of the lenses into your eyes.

Polished Edge: Provides the invisible appearance around the lens edge.

Roll & Polish: Reduces edge thickness and provides invisible appearance around the lens edge.
