Differences: 

1. Anti blue light lenses (also called Blue Light Block Lenses) mainly block blue light radiation from artificial light sources, while anti radiation lenses block ultraviolet and electromagnetic radiation. 
2. Anti radiation function: Currently, most lenses have this function, which means that anti radiation is a popular function. But radiation resistant glasses cannot prevent blue light. Blue light is a type of light with wavelengths between 380nm and 500nm

Anti blue light glasses: 

UV and blue light from the sun entering the eyes can produce a large amount of free radicals, causing cataracts, macular degeneration, and even cancer. Ultraviolet rays can generally be filtered out by the cornea and lens, but blue light can penetrate the eyeball directly to the retina and macula. There are anti blue light lenses and non blue light lenses available on the market. Relatively speaking, anti blue light lenses play a certain role in eye protection. If you choose well-known anti blue light lenses, it is recommended to choose a well-known brand glasses store or hospital.

Anti radiation glasses: 

Anti radiation glasses are made by adding some compound substances during the lens processing of glasses, and applying relevant anti radiation film layers to the lenses. Because radiation from computers and other devices is caused by electromagnetic waves, generally speaking, electromagnetic waves have a certain amplitude and wavelength. The compound medium and radiation film of radiation resistant glasses utilize this principle to achieve radiation protection by utilizing electromagnetic waves of different wavelengths to interfere with each other.
