2. PHYSICAL AND OPTICAL PROPERTIES

Dingxin® 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 Dingxin® 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, Dingxin® Gray and Brown lenses Dingxin® 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 Dingxin® lenses like a real sunglass lens.

The transmission features of these two photochromic lenses are described in the

following table and graph.
