How to choose contact lens prescription?

When I walked into the campus and looked up, I saw that there were many more people wearing glasses than on campus a few years ago. Because now more and more students do not pay attention to protecting their eyesight. However, after wearing glasses, there are many troubles. Wearing glasses for a long time will put pressure on our nose bridge. Our ears also suffer. And the lenses are sometimes particularly fragile. It makes us very distressed. So some people choose to wear contact lenses. This way we don't have to worry about the frame. However, when choosing contact lenses, we must also pay attention to one issue, which is the degree of the contact lenses. Many friends have misunderstandings in this regard. So how do you choose?

1. If you are not nearsighted, you can only choose 0-degree cosmetic contact lenses. The lowest degree of ordinary transparent contact lenses is 100 degrees, and there are no lenses below 100 degrees.

2. If your myopia is below 400 degrees and you do not have astigmatism, you can choose the degree of contact lenses directly according to your frame degree. Because the degree is low, no conversion is required when fitting contact lenses.

3. If myopia is more than 400 degrees, the degree needs to be appropriately reduced according to different stages. From 400 to 550 degrees, reduce by 25 degrees; from 550 to 725, reduce by 50 degrees; from 750 to 850, reduce by 75 degrees; from 875 to 1000, reduce by 100 degrees.

4. When converting contact lens degrees, if a certain degree is not available, you can choose a similar degree. For example, 800 degrees minus 75 degrees is 725 degrees. If 725 degrees is not available, you should choose 700 degrees, and so on. Generally speaking, lenses with a slightly lower degree will be more comfortable to wear than lenses with a slightly higher degree.

If you don’t know your own eye degree, you must not choose randomly. You must base your choice on your actual degree to achieve the effect of comfortable wearing and vision correction.

Kind tips:

1. In theory, if the degree of the glasses you wear is not enough, myopia can only develop to another 400 to 500 degrees and then stop. Be careful not to get too close to the computer when looking at it. So there is a positive side to not getting new glasses.

2. Poor vision can sometimes cause some inconvenience. If the vision of the two eyes is very different, there is a risk of strabismus, which is why we wear glasses.

3. As long as you look at close objects for a long time, you will develop myopia or its condition will worsen even at the age of 40. The eyes are adaptable, so preventing and treating myopia is necessary at all times.

4. If the degree of myopia is too high, there is a risk of myopia complications, which makes it even more necessary to prevent and treat myopia.
