How do I know how myopic I am?

The problem of myopia troubles more and more young people. Because of myopia, in daily life, things become more and more blurry, and sometimes they forget to wear glasses, which will have a certain impact on the patient's daily life.

So how do you know how much myopia you have?

1: A ruler;

2: A well-lit environment;

3: A clear photo or picture with details on it;

Test steps:

Place the photo on a horizontal plane at eye level, with the photo plane perpendicular to your line of sight;

Adjust the distance between the photo and your eyes until you can see all the details of the photo clearly;

Record the vertical distance between the photo and the pupil at this time (in cm);

Note: If testing monocular vision, cover the other eye with a small medium gray object;

If both eyes are used at the same time, the combined vision of the two eyes is tested, which is generally higher than the vision of one eye.

During the entire test process, the eyes should be protected from direct light and sufficient light should be ensured in the photo; otherwise the test results will be inaccurate.

Do not let objects touch your pupils directly, be careful to protect your eyes! ! !

Visual acuity calculation:

Naked eye degree = -10000/distance

For example: Test distance = 40.0cm

Then degree = -10000/40.0

=-250 (degrees)

That is, the visual acuity of this eye is 250 degrees myopia.

It should also be noted that if there is astigmatism at the same time, the tested degree will be inaccurate.

This method gives a comprehensive degree, which will be higher than the simple myopia degree.

But generally speaking, it is recommended to go to the hospital for accurate eye testing, because the measurement will be more accurate. In addition, there are more and more people suffering from myopia, and their age is getting younger and younger, especially children under 18 years old.
