2. PHYSICAL AND OPTICAL PROPERTIES

New Vision Photochromic lenses are produced of high quality, low density, and middle index (1.56) photochromic monomers. The photochromic dyes are fully incorporated into the material rather than applied to the surface. The lenses keep the ability to respond to UV light longer and are more color consistency.

Refractive Index N=1.56

ABBE Number V=42

Density 1.14g/cm³

                                                                                                                                       
 3. TRANSMISSION PROPERTIES

Transmission properties of New Vision Photochromatic Gray and Brown lenses are very superior compared to other photochromic lenses in the market; they can reach 20% ~ 21%  transmittance after 15 minutes of darkening by ISO standard solar simulator. When  faded indoors, New Vision Gray and Brown lenses New Vision back to 65% ~ 70%  transmittance within 2 minutes.

Transmission drop of the darkening state mainly happens within the 30 seconds  (absorption increase of more than 65%), and makes the darkened New Vision lenses like a real sunglass lens.

The transmission features of these two photochromic lenses are described in the  following table and graph.
