Prescription Lenses

We have the experience to discuss the different options available and make recommendations as to what lens design and options may serve you the best.  Several popular options include:

 

Hi-Definition Lenses

Also known as “free-form” lenses, these take advantage of a customized, computer generated surface design for your specific prescription.  The advantages are sharper optics and a wider field of clear vision compared to conventional lenses.  Hi-Def lenses are available in both single vision and progressive lenses.

 

Progressive Lenses

Also known as no-line bifocal lenses, these lenses give clear vision at distance, intermediate and near.  There is no line to jump across and they are cosmetically appealing.   We know from experience which lenses work better than others and which occupations, like truck drivers, require special considerations.

 

Computer Lenses

For those who spend significant time at the computer or in an office environment, these  lenses are designed specifically for you.  They allow the computer to be in focus in normal head posture, without having to tip your head back.  The top of the lens gives additional clarity out to about ten feet.  The bottom of the lens focusses at a normal reading distance to see small print clearly.  These lenses can be a real necksaver!

 

Pheonix/Trivex Lens Material

This improved lens material offers a thinner, lighter lens with a durable scratch resistant coating.  The material is impact resistant.  It has a relatively high Abbe value, which means the optics are clearer with less aberrations compared to certain other lens materials.

 

Antireflective Coating

This treatment reduces glare from the surface of lenses and is especially helpful with night driving and for those who work with the public.  The treatment allows about 8% more light through the lens, giving clear, natural vision.  There is a vast difference in the quality of anti-reflective coatings, so we recommend the best ones with a 2 year anti-scratch warranty and easier cleanability.

 

Photochromic Lenses

These lenses are popular here in sunny South Central Idaho.  The newer products get darker outside and clearer inside than ever before.  They are still temperature-dependent so they get darker in cold weather and they don’t get very dark behind the windshield of a vehicle, which blocks most of the activating UV rays.

 

Polarized Lenses

This sunglass feature selectively reduces glare from horizontal reflective surfaces, like water or ice on the road.  They tend to reduce eye fatigue in these environments, but they can sometimes make viewing older LCD displays difficult.  There are now even lenses that combine photochromic and polarized lens features.
