HOW TO TEST FOR THE AUTHENTICITY  OF BLUE LIGHT GLASSES 🚀🚀🔥🔥(Cntd)

💎The blue sky test
The blue of the sky should look yellowish through your clear lenses. Clear lenses have a slight yellow tint that isn’t super noticeable when you’re wearing your glasses on your face. To check if they’re tinted, go outside and hold your glasses up toward the blue sky on a clear, bright day. If the sky looks warmer or yellow through the lenses, then they’re blocking at least some blue light.

💎Of all these, an instrument called spectrophotometer is a great way to test your blue light blocking lenses. It is the best way to accurately and precisely measure how much blue light is being filtered. The spectrophotometer test can be done in specialised labs or optical stores.
