1、 wear contact lenses, and then wear sunglasses
Contact lenses themselves are prone to corneal hypoxia, dry eyes and other symptoms, and then wear sunglasses, double-layer lenses are more likely to cause dry eyes, visual fatigue, pay attention to the appropriate control of wearing time.
2、Color changing lenses
Color changing lenses can change the color of the lenses according to the strength of the environmental light, and the color of the lenses will become darker when exposed to the sunlight, which not only corrects the eyesight, but also achieves the effect of blocking the strong light.
However, there is a process to change the color of the lens, and it takes a period of time for the light and dark environment to change rapidly before the color changes gradually, so the sudden change in the environment will cause the vision to be unclear.
3、 tinted lenses
tinted lenses can also play a role in blocking the effect of strong light eye protection, tinted lenses have been dark, the color does not change with the change of light, can make the eyes in the process of pupil dilation for too long, the indoor environment of the dark lens clarity is poor, should not be worn indoors.
Color change lenses compared with tinted lenses, light transmission is worse than general myopia glasses, visual quality has a higher should not be used.
4、 sunglasses clip-on
If necessary, can be directly clamped into the frame glasses; clip-on style is limited, the shape is not commensurate with the myopic glasses, affecting the aesthetics, and the individual frame glasses can not be used.
