The principle is different. The principle of polarised sunglasses is to use the linear arrangement of molecules inside the lens to filter and eliminate all types of eye-damaging glare; non-polarised sunglasses are ordinary lenses plus very fine metal powder used to filter glare to prevent too much sunlight affecting the line of sight.
The effect is different. Polarised sunglasses have a stronger blocking effect on strong light, which can improve human vision, reduce eye fatigue, and also block ultraviolet rays, so the eyes can avoid being violated by ultraviolet rays; non-polarised sunglasses do not have the effect of reducing visual fatigue, but their transmission can satisfy most of the daily needs of sun protection.
Different use scenarios. Polarised sunglasses are more suitable for outdoor activities such as driving, fishing and holidays; non-polarised sunglasses are more suitable for daily commuting and shopping.
In addition, polarised sunglasses have the following disadvantages compared to non-polarised sunglasses
Fear of high temperatures. Polarised sunglasses have a polarising film inside that can burst in high temperatures, causing the lenses to break.
They cannot be cleaned in an ultrasonic cleaner. Otherwise the lenses will turn black.
When looking at the windscreen of a car or the screen of a mobile phone with a film applied to it, there is a colour dispersion phenomenon which disturbs the visual effect.
