1. Unconventional physical optics design of 38mm diameter, 40mm focal length, 130 degrees angle, makes a much wider field of view.
2. High-definition imported optical glass with 19 processes reaches 99.7% light transmittance, far more than 93% that of ordinary resin lens, by which means more comfortable experience.
3. Three layers anti-blue light and anti-UV glass coating process protects eyes and filter lights harmful to our eyes, reducing eye strain caused by long time watching VR.
