Color-changing glasses should not be worn for a long time. Color-changing glasses may change color as the light changes, and are more suitable for patients in some special occupations, such as drivers who work outdoors for a long time may need shade and feel comfortable wearing color-changing glasses. Elementary and middle school students or ordinary patients who do not have special needs are not good to wear color-changing glasses instead. Because the color-changing glasses are not as good as imagined, the color change from outdoor to indoor is a gradual process, the color may go from bright to dark, and will not become transparent all at once, which will affect dark vision. In addition, primary and secondary school students used color-changing myopic glasses, preventing the effective blue light from entering the retina, but may lead to myopia development too fast.
