How many degrees does progressive multifocal lens reduce vision in a year? Is there an authoritative store selling this kind of glasses in Linyi? How about the price?

Teenagers and adults wear progressive multifocal lenses. Adult progressive lenses mainly solve the trouble of seeing far and near without changing glasses. Generally, people who are nearsighted feel that presbyopia will be fine after 40 years old. As for many people whose farsightedness is only presbyopia, it is unnecessary, depending on their financial ability.

Although the juvenile progressive film can effectively alleviate the growth rate of myopia, it is not suitable for everyone, nor can it absolutely alleviate the degree increase. If used improperly, it will be counterproductive. Generally speaking, if you wear it correctly, it will not exceed 50 degrees a year. However, if the adjustment function of human eyes is added to the lens, people themselves have no adjustment function. Personally, I think the lens of Zeiss is good, and the night of essays is ok. Generally, there are better optical shops, and the lenses are all the same, depending on the discounts of various businesses.
