The vision is determined by the refractive level of the eyes’ crystalline lens, clarity, and the length of the eye axis. To a certain extent, it can reflect the health of the eyes, and most of the time, the vision measured in the routine physical examination is vision.

Generally speaking, vision correction refers to the vision after wearing glasses. The vision without wearing glasses is called vision.

For example, a myopia patient has a vision of 0.1 without wearing glasses, and the vision reaches 1.5 after wearing glasses. The former is called vision, and the latter is called corrected vision. Some people think that ‘correction’ means that the vision will be restored (corrected) after wearing glasses, such as myopia, the vision will be ‘corrected’ from 0.1 to 1.5 after wearing glasses, and not wearing glasses, the vision will be ‘corrected’ from 0.1 to 1.5. This is an incorrect definition.

There is also a way to measure eye vision from 4.0 to 5.3, which is equivalent to from 0.1 to 2.0.

Eye Prescription

The vision and eye prescription are not immediately arranged and combined; the eye prescription must be measured accurately with a vision test instrument and glasses. Therefore, the eye prescription cannot be estimated according to vision. If the eyes are normal, myopia can be corrected to standard vision by wearing glasses or laser myopia surgery.

Maintenance Methods

Distant Gazing

Find a grassland or green forest 10 meters away: the emerald green is due to the shorter wavelength of light, appearing in front of the fundus yellow spot, promoting the adjustment and release of stress around the eyes, relaxing the ciliary body, and relieving eye fatigue. Do not squint or blink continuously, clear your mind, concentrate, and stare at the distant grassland or falling leaves for 25 seconds, distinguishing the outlines of the grass or leaves. Then, hold your left palm slightly higher than 30 centimeters in front of your eyes and recognize the palm’s fingerprints one by one from the beginning to the end, for about 5 seconds. After looking at the palm’s fingerprints, gaze at the distant grassland or falling leaves for 25 seconds, and then look at the palm’s fingerprints again. Repeat this 20 times in 10 minutes, do it three times a day, and increase the training frequency if the eyesight is declining significantly.

Crystalline Exercise

In a blink: support your face with both hands, let your gaze rotate 10 times in the order of up, down, left, and right, and then rotate 10 times in the opposite direction and clockwise.

Find a scene 3 meters away (such as: paintings on the wall), and then raise your right hand slightly above your eyes, straightening it (about 30 centimeters), recognize the palm’s center and fingerprints, and then recognize the distant object, moving your gaze back and forth between the two as quickly as possible. Do this 20 times.

Massage and Manipulation Exercise

Whether sitting or lying flat, close your eyes naturally, and then massage the acupoints around the eyes. The selection of acupoints should be precise, and the technique should be light and quick, with a slight sense of acid and胀as the standard.
