ECP’s can differentiate themselves and gain a competitive advantage with premium glass lenses. Now there is a high technology digital option for patients who prefer glass lenses. The benefits of glass lenses include the following: Clear optical clarity for better vision, built-in scratch resistance that lasts for the life of the lenses, very stable base material for AR & Mirror treatments, more scratch-resistant in industrial environments, impreg­nated glass color is very stable and never diminishes over time or due to exposure to sun or heat, photochro-mic performance never wears out and is impervious to oils and solvents. These lenses are great for sunglass wearers who appreciate the benefits of glass lenses found in the world’s best selling sunglasses. The proof of glass’s unsurpassed excellence is also found in its use in top quality tele­scopes and microscopes. CrownView Progressive lenses offer the lowest minimum fitting height in glass progressive lenses and can accommodate smaller frames to decrease weight. They offer larger diameter progressives lens blanks for greater cut-out availability. CrownView lenses feature the largest selection of glass materials/colors available for progressive lenses in the marketplace. Some special colors available include occupational filter glass for sodium flare protection and an extreme blue blocker canary yellow which blocks 100% of all light up to 450nm. CrownView is also available in an aspheric/atoric single vision design.

OOPS! We forgot a couple of things!

America’s First Premium Glass Digital Free-Form Lenses

CrownView progressive lenses are a soft design with smooth power changes for effortless adaptation and increased patient comfort. CrownView lenses are a 100% digitally surfaced full back side progressive design.

Soft & Smooth Design - Gradual rise and fall of the mean power as the eye travels across the lower horizontal portion of the lens. This smoothing of the mean power has the following benefits.
• Provides a premium progressive lens design with superior viewing comfort.
• Allows for natural eye movement.
• Provide sharp viewing in any direction.
• Minimizes the swim effect experienced with traditional progressive designs.
• Minimal patient adaption times resulting in greater patient satisfaction.

Vision Track Engineering - This is employed during the Rx calculation phase to modify the lens surface geometry for the purpose of reducing oblique astigmatism. The specialized Rx calculation software incorporates ray tracing over the entire lens surface to correct for viewing errors. The amount of oblique astigmatism experienced will depend on the prescription, how far away from the lens center the patient is viewing, and whether the lens curve is flat or steep. Generally, the flatter the lens, the more oblique astigmatism will be experienced. Oblique astigmatism will cause the patient to see less clearly when viewing off center. Vision track technology has the following benefits.
• More consistent optical performance over a wider range of prescription powers.
• Wider viewing areas for hyperopes.
• Improved distance area for myopes.
• Improved image quality in the principal viewing areas.
