The closer the distance between the eyes, the better, as long as it does not touch the eyelashes, to reduce the aberration of cheap eyeglasses near me. The eyes are also less likely to scan the edges with poor imaging, reducing the prism and improving comfort.

Especially for people with anisometropia, it is strongly recommended to wear a small frame made of board materials. Unequal images will be relatively reduced, and the difference in prism size between the eyes will be small, which is more comfortable.

A slightly curved surface can also improve comfort, but in fact, a larger frame surface makes it difficult for the eyes to see the edges, similar to the previous one. But when children wear protective children's eyeglasses lenses, they should try to have their face curved to 0 and the frame flat, which will have a better protective effect.

Because the out-of-focus area cannot be seen, there is no effect as expected. The defocused area below the nose has the greatest effect, as it is internally rotated when viewed closely by the human eye. Therefore, the amount of heart movement should be small, otherwise, this area will be worn off and the prevention and control effect will be poor.

The lens should not be installed too tightly in the eyeglass online frame, otherwise, the lens will be compressed and deformed, causing stress and making the wearer feel particularly dizzy. This situation is very common because if the lens is worn down, it is easy to fall out and needs to be replaced, resulting in additional costs. Some stores would rather make it larger, so the screws on the metal frame must be completely closed to be considered suitable for processing.
