Abstract: hyperopia is due to the short axis of the eye. When the adjustment state is not used, the main focus falls behind the retina after the parallel light passes through the refraction of the eye. The retina cannot form a clear image. Therefore, hyperopia often needs to use adjustment to strengthen the refractive power of the eye, so that the light entering the eye can gather on the retina and become a clear image.
what causes hyperopia
1. Curved hyperopia: curved hyperopia can also be called curvature hyperopia, which is caused by the relatively small curvature of any refractive body surface in the ocular refractive system, that is, the relatively small corneal curvature.
2. Axial hyperopia: axial hyperopia is a kind of hyperopia. If the anterior and posterior axis of the eyeball is short, it will lead to hyperopia, which is common in refractive abnormalities. The eyeballs of some newborns are almost in the state of hyperopia.
3. Refractive index hyperopia: this kind of hyperopia is usually caused by the decrease of refractive index of refractive coal in the eye, but the probability of this situation is relatively small.
to prevent hyperopia, you might as well try the eye rotation method
the first formula: look up and down directly at
to close your eyes, inhale when your eyes rotate upward, and exhale when you look down; Then inhale when your eyes turn down and exhale when you look down. Do it 20 times (rotate up and down once). The second formula of
: look at
horizontally from left to right, close your eyes, inhale when your eyes turn to the left, and exhale when you look down; Then inhale when your eyes turn to the right and exhale when you look down. Do 20 times (left and right movement is counted as 1 time). The third formula of
: turn clockwise, close your eyes, and inhale when your eyes rotate from lower left to upper left; Exhale as your eyes rotate from top right to bottom right. Do it 20 times (turn left and right once). The fourth formula of
: turn around and look counter at
, close your eyes clockwise, and inhale when your eyes rotate from lower right to upper right; Exhale as the eye rotates from the lower left. Do it 20 times (turn left and right once). The fifth form of
from afar, open your eyes, select a fixed point in front of your eyes 100 meters away (such as mountain peak, roof, trees and scenery), open your eyes and stare at the point, and breathe naturally for 1 ~ 2 minutes. The posture of
is better in sitting, breathing should be slow, and the intention and force should be light when moving the eyes.
