Frequent replacement of glasses requires the eyes to adapt to the glasses time and time again. The material, refractive index, and optical properties of each pair of cheapest eyeglasses are different.
Therefore, during the process of changing glasses, if the degree increases, the refractive index changes, the material changes, or the properties change, it will cause the eyes to compensate multiple times in order to adapt to the glasses again. Perhaps this is the reason why frequent replacement of glasses increases the prescription!
In modern society, an era is iterating, and products are also iterating. I remember during our junior high school years, we used to have kids' eyeglasses online that were uniform, but now they have evolved into frames made of various materials, lenses made of different materials, from circular and elliptical shapes to square, rectangular, and polygonal shapes.
Progress in every aspect. Whether it's the lenses, frames, or other reasons, it can cause you to impulsively change your glasses. However, frequent replacement of glasses requires the eyes to adapt to their time and time again. Who can guarantee this process?
I don't know how many people in real life encounter these situations and are always trying to sell you the thinnest lenses. How many people can restrain their impulses in their hearts?
It is not recommended to change glasses frequently as it can increase the burden on the eyes. If you need to replace your eyeglasses online cheaply, please try to keep the parameters consistent. It's not that the lower the refractive index, the thinner the better, but that your eyes can adapt as quickly as possible.
Glasses are used to see far, there is no special requirement, just enough is enough. Please treat your eyes kindly and deeply appreciate their importance.
