The so-called stress refers to the compression and deformation of the cheapest eyeglasses lens by the inner ring of the frame, which causes light to refract differently through this deformed area, resulting in a change in the actual degree and causing the light to wander around, making it uncomfortable for people to wear.
I'd rather be tight and not do things that are difficult and thankless. A larger proportion of people are probably still unaware of the existence of stress. I believe that if those who know about stress still ignore it, they will not be at ease either.
At present, excessive stress on the entire frame is a seriously overlooked issue. The lenses of the full-frame glasses made of sheet metal are too tight and difficult to remove. They also need to be heated by a baking lamp to soften the frame before they can be removed. This kind of glass is not suitable for stress.
Of course, stress cannot be completely absent. As long as a small amount of stress appears at the edge of the nose or nose, and the eyes cannot see this area at all, the problem is very small.
Reducing the size of the lens as soon as it is installed is not a problem, and loosening the lens may also reduce stress. Unless it is too tight and the lens has deformed beyond repair over time, there is no solution. It is recommended to replace the lens promptly. The lens and the inner ring of the frame are squeezed against each other, and the frame is also easily damaged.
The reason for thermal expansion and contraction may lead to increased stress in the later stage. Regular inspection and maintenance of glasses, as well as regular replacement of glasses, is a good habit. If you want to eliminate the stress on your glasses, you can go to the best place to buy eyeglasses.
