At present, there are two prescriptions for reading glasses. One is to adjust the power of glasses with clear objects at close range, plus 1/3 of the power for adjustment. The other is to use low power that can see close objects clearly. The practice of many elderly people has proved that the latter one is better between two methods.
Is blue light blocking worth it?
There are two main problems with anti-blue glasses currently on the market. One is that the place to be prevented is not preventable, and the other is that people have color casts due to wrong protection and aggravate visual fatigue. Studies have shown that our eyes are the most intolerant of blue light in the 400-440 nanometer band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. However, the blue waveband of electronic products is between 450 nanometers and 490 nanometers, so most anti-blue glasses have little protection in this waveband. In addition, the blocking rate of anti-blue glasses is 20%~30% to achieve a good anti-blue light effect, but now the blocking rate of anti-blue glasses on the market has basically reached 80%~90%. All in all, these blocking blue light glasses cannot prevent the blue light in the 450-490 nanometer band, and their high blocking rate will also cause a color shift, which makes people more likely to have eye fatigue and headache.
In daily life, the intensity of blue light is low, not enough to cause damage to the fundus, so ordinary people do not need to wear anti-blue glasses unless they are working in extremely strong light conditions or working in special environments. To protect the eyes, it is more important for people to develop good eye habits. For example, wear a pair of suitable glasses and read insufficient light and at an appropriate distance. Avoid using electronic products for a long time. Take a break for 20 to 30 seconds every 20 to 30 minutes, and look at the distance regularly. If you have dry eyes while reading the electronic screen, remember to blink to 12 times per minute. It is best to wear sunglasses when outdoors.
Advantages of Photophobia Glasses
