The Vixen solar observation glass (solar eclipse viewer) uses a solid shield called 'Solar Protec', which is made of a thick acrylic resin coated with evaporated aluminum. This not only reduce visible rays of light so you can view the sun comfortably, but also infrared and ultraviolet rays of light, that are harmful to the unaided eyes, are eliminated It completely protects the retinas of your eyes from damage which could be caused by solar observation. Unlike thin film type materials, which can be in danger of a break or a pinhole, the Vixen's solar eclipse viewer is designed to be the best protection available.
The 'mask' design of the Vixen solar observation glass has been designed uwith the supervision of an ophthalmologist. The safety standard of th Vixen solar observation glass has been highly rated and it was authorized as a recommended, safe solar observing instrument by the Japan Committee for the International Year of Astronomy in 2009.
