What is 300 degrees of myopia

Myopia has become an increasingly serious eye problem. In modern society, basically more than half of the people suffer from myopia, and the incidence rate of myopia is also increasing year by year. It can be seen that myopia has become a problem that everyone has to prevent. Some people become nearsighted because of habits they developed since childhood, so people with myopia should generally protect their eyes better to prevent their myopia from getting worse. So if a person's eye degree is 300 degrees, what will his degree be shown as on the eye chart?

The 300-degree glasses are 0.3 when compared with the old eye chart, and 4.5 when compared with the new eye chart. If you have been diagnosed with true myopia, it is recommended that you wear glasses except when washing your face and sleeping, because after wearing appropriate glasses, myopic patients are in a normal state of vision, and the adjustment and convergence functions have restored a natural relationship. Wearing glasses can not only improve vision, but also make the adjustment and convergence functions of glasses have a normal coordinated relationship when reading and working at an appropriate distance, avoiding eye fatigue. But you should also pay attention to eye hygiene. If you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and worsening of myopia.

Generally speaking, for myopia of more than 300, the strength is about 0.25. However, each person has individual differences, and the eye muscle adjustment ability is also different, so the gap can be quite large. It is currently recommended to go to a regular hospital for an eye examination, vision, optometry and trial, and then wear appropriate glasses. Pay attention to rest at ordinary times, do not use your eyes too much, especially mobile phones, computers, televisions, etc., look at distant objects and green foods more often, and participate in more outdoor sports, such as playing basketball.

Because 300 degrees of myopia is a diopter, the point you look at is a question of how much corrected vision you have. These are two completely different concepts. Some people can see 1,0 at 300 degrees but some may only see 0,2. Visual acuity and refraction are two different concepts. You can only know how much you can see at 300 degrees by seeing it.

In fact, the logarithmic vision and naked eye vision tested on the eye chart have no direct correlation with what we usually call the degree of eye (eye refractive power). For example, 4.5 may mean 300 degrees of myopia or 700 degrees, because the accommodation power of our eyes is different. To know the exact degree, you need to go to the hospital's ophthalmology department for a routine vision test and computer optometry test to determine it.
