1. Deviation of vertex. Cheap Ray Ban Sunglasses of nominal top Coke degrees value should for 0.00D, lenses manufacturing Si of deviation or lenses and mirror frame of Assembly inconsistent, are has may produce top Coke degrees of deviation (that with or are or negative of top Coke degrees), if beyond must range, is wearing who may will is depending on property deformation, serious of is will effect wearing who of vision health.
2. The Prism. Sunglasses-Prism should be 0.00 δ if lens with Prism, you will move depending on the coke, if you exceed allowed range, can cause of binocular vision cannot be one, or the imbalance between high and low, adding to the wearer's eye and optic nerve disorder control, can also lead to disorders of neural regulation of serious or Arabists.
3. The light transmittance. Characterization sunglasses feature light transmittance project is an important indicator of my existing product standards by this function are divided into 3 categories: visor mirrors, tinted sunglasses and a special purpose sunglasses while GB10810.3 transmission specification and methods of measurement in the standard be broken down into 4 categories. Different categories, sunglasses use completely different.
4. Average transmittance of UV. Cheap Ray Bans sunglasses ultraviolet rays through the case, through the smaller, anti-UV capability, the stronger.
