Sunglasses and pupil dilation

 

Sunglasses and pupil dilation

Since we are talking about human health here

There is a bad habit prevalent in the world that most people wear sunglasses (ordinary accessories) and of course no one buys what is against ultraviolet rays (you would like it expensive), and if you prefer to use ordinary accessories, your eyesight will weaken with time.

 

During the day the pupil of the eye narrows so that it does not enter a lot of light and protects you from the harmful ultraviolet rays emitted from the sun, so when you wear sunglasses (ordinary accessories) you prepare for the eye that it is night time and therefore the pupil of the eye will widen and a large amount of harmful rays will enter and your eyes will weaken with time, buy from the expensive, which says against uv rays, or don't buy.
