Description
[technical field]
The present invention relates to resin lens technical fields, specifically, to be a kind of be by the refractive index of ultraviolet photo-curing
1.60 resin lens and its manufacturing method.
[background technique]
Spectacle lens are passed through made of chemical polymerization as dedicated lens resin (being commonly called as monomer).The exploitation of optical resin is ground
Studying carefully work starts from the twenties in last century, has up to the present produced the optical resin of tens of kinds of different sizes.Wherein, day
The existing various new resin commercialization of the country such as sheet, the U.S., Germany and Belgium.Optical resin divides thermoplastic resin and thermosetting property
Resin, the thermoplastic resin by taking polycarbonate (PC) as an example are mainly used as sunglasses lenses and partial correction eyeglass, its advantage is that at
The features such as type is fast, forming cost is low, the disadvantage is that internal stress is bigger, optical property is general.With polymethyl methacrylate
(PMAA), the thermosetting resin for polyurethane (PU) and poly bis allyl diglycol carbonates (CR-39) has optical property
