Therefore, anti-blue light glasses are designed to reduce the impact of blue light on the eyes by absorbing part of the blue light. Some anti-blue light lenses use special coatings, while others use special materials for this purpose.

Secondly, these glasses can also improve sleep problems, because too much blue light can interfere with the secretion of sleep hormones. In addition, anti-blue light glasses can also protect the eyes from ultraviolet rays and other harmful rays. However, anti-blue light glasses do not completely solve vision problems, such as eye strain or dry eye syndrome, they can only reduce symptoms. Moreover, anti-blue light glasses are more expensive than ordinary glasses, and consumers need to evaluate whether they are worth buying.

In addition, if you have vision problems, such as nearsightedness or astigmatism, you need to consult your doctor first whether anti-blue light glasses are suitable for you.
