Do you need to wear glasses to drive?
In the evening, lights from street lamps, buildings, and other vehicles create a lot of reflection on the windshield, making it hard to see. It's even worse when it rains. But if your glasses have an anti-reflective coating, they can reduce the glare and reflections, allowing you to see more clearly while driving at night.
Need to re-adapt to new glasses
When the glasses were damaged, the glasses were not replaced in time. As a result, the nearsighted person wears old glasses and continues to look at things. The old glasses have 'remodeled' the eyes in the long-term process, and the eyes have adapted to the old glasses. Therefore, even if the power of the new glasses is the same as that of the old glasses, the new lenses will feel brighter. In this case, eyes produce uncomfortable symptoms. It is recommended to use the new glasses early the next morning. After a night's rest, the eyes will be easier to adapt to the new glasses. After a few days of continuous wearing, the dizziness symptoms will disappear.

The first inventor of wearable glasses is not known. However, it was the Romans who first discovered the use of glass to enhance their ability to see small words, creating small magnifying glasses with spheres. The first known wearable glasses in history appeared in Italy in the 13th century. They were used mainly by monks, and became popular little by little during the Renaissance, as the technology improved. As their popularity grew, the Italian glasses spread throughout Europe, mostly within reach of the wealthy. Because learning was a prized attribute during the Renaissance, glasses were a status symbol of wisdom and prosperity. With the temple extending above the ear, the glasses are no longer required by hand.
Who should wear blue light glasses?
Teenagers, middle-aged and old people need to wear blue light glasses. The lens of a teenager is clear, pure, and still developing. Their eyes are less resistant to blue light than adults and are more vulnerable to long-term exposure to blue light, which can promote the development of myopia. Teenagers study more nervous, are free to love to play computer games, love to watch TV programs. Blue light damage can be said to be everywhere. As a result, teenagers are among the biggest victims of blue light.
