Comments

  • Choosing a lens category should take into account the local intensity of light, how sensitive the tinted glass wearer is to glare, and the need for UV protection (especially at high altitudes).
  • The highest categories (cat 4 or less than 8% transmission for both European and Australian standards) being devoted to specific applications (such as mountaineering or protection of hypersensitive eyes), they are not suited to driving, an aspect which international standards also take into account (traffic signal vision tests data).
  •  Regulators are actively working on a new, global standard.
  • Corning has chosen to offer only medium or high levels of protection, thus not to address category 0 or 1 tinted glass.

Corning Specialty Glass offers a wide variety of glass solutions, including tinted lenses, photochromics, and transparent UV filter glass lenses for the manufacturing of polarized tinted glass. Our products, which you will find in some of the world’s leading tinted glass brands, comply with all international standards and beyond.

Outside on a sunny day, the brightness of the light ranges from about 1,000 lumens in the shade to more than 6,000 lumens. When the brightness of the direct or reflected light gets to about 4,000 lumens, our eyes begin to have difficulty absorbing the light. What we see when we try to look at these brighter areas are flashes of white; this is glare.
