| Video Discription | It is very critical to understand whether the sunglasses that you are wearing are actually giving you protection from the ultraviolet rays of the sun. Not all glasses will actually protect you from the ultraviolet rays of the sun which can be very harmful for the eyes. A common understanding among people is that the higher the tint of the glass, more the protection of the glass against the ultraviolet rays. However this is not true. A glass with low tint can also be ultraviolet protective. The property of a glass to be ultraviolet protective depends upon the thin layer of coating put over the sunglasses. Some sunglasses have better ultraviolet coating than the others. The best way to find out if a sunglass is ultraviolet protective is by a spectrophotometer. This can measure the UV protection ability of the sunglasses. So the simplest way is to take it to an eye hospital and give it to the technician. They will be able to measure and tell how protective is our glass. K8ZgqHv2-9s |
