What time is 450 degree myopia

summary

I took part in the physical examination of civil servants in Guangdong Province in May, and found a more interesting thing, that is, how to convert between myopia and naked eye vision, such as what time is 450 degree myopia, but after looking for all the information, I found that there is no direct conversion formula between the two, so there can only be a rough number for the problem of what time is 450 degree myopia.

What time is 450 degree myopia

First, to solve the problem assumed by the author above, myopia and uncorrected visual acuity are not a concept. There is no basis for conversion between them. Only about 450 degrees of uncorrected visual acuity can be calculated.

Second, naked eye vision refers to the clarity of seeing things directly without wearing any glasses. Myopia refers to how many degrees the eye has. It's two different things, but there are also two parameters associated. Often the higher the degree, the worse the vision, otherwise the worse the vision, the higher the degree. It is inversely proportional.

Third, 450 degree myopia, if you want to be a soldier or special police and other special industries, you can only recover through surgery, there is no other way.

matters needing attention

450 degree myopia, if the situation is good, may have 0.3 vision, if the situation is slightly worse, may be 0.1 vision. Myopic people can supplement the following nutrients: 1. Protein: as far as sclera is concerned, it can become the tough shell of the eyeball because it contains a variety of essential amino acids and forms a very strong fibrous tissue. Although sclera has certain tenacity, it is still weak in the anterior and posterior diameter of ocular axis. Meat, fish, eggs, milk and other animal foods are not only rich in protein
