Precautions for the selection of color-changing lenses

1. The power difference between the two eyes is more than 100 degrees. It is recommended to choose a film-variable lens. The thickness of the two lenses will not be different, which will cause different shades of lens discoloration.

2. Wearing a color-changing lens for more than one year, if one is damaged and needs to be replaced, it is recommended to replace the two together. In this way, the discoloration effect of the two lenses will not be different due to the different use time.

3. If you have patients with high intraocular pressure or glaucoma, remember not to wear color-changing lenses or sunglasses.

4. The color-changing lens changes color according to the intensity of ultraviolet rays, so even if it is cloudy, it may change color.

5. If the driver chooses the color-changing lens, the color-changing lens may not change color in the car. This is because most of the front windshield of the car now has the function of blocking ultraviolet rays, so the ultraviolet color-changing lens in the car will not be isolated. Discoloration, but now some manufacturers have developed in-vehicle color-changing technology, it will not happen in the car lens does not change color.
