Under what circumstances is it possible to change vision with a laser?

I don't think it's best not to use lasers to change vision under any circumstances, because if lasers are really useful, then there really is no myopia in this world. It is undeniable that the laser can indeed change your vision, but it is also very large in the later stage. If you don't treat yourself carefully, you are likely to become blind for the rest of your life.

Of course, there will be a lot of people who will take this kind of risk, if you can think of pilots, and it is the kind of desire that has been there since childhood. It's like if you don't want to be a pilot and you feel that your life is meaningless, you can choose to try lasers. After all, pilots are still very strict about vision, but I think having a pair of eyes that can see is much more realistic than your dreams.

You can choose not to chase your dreams, you may be disappointed, but if you choose a laser to change your vision, if something does happen, what will you do in the future? So don't try this challenge, it's just too risky.

Laser surgery for myopia can restore the level of corrected vision that existed before surgery.

How much is the corrected visual acuity before myopia surgery, and how much can be recovered after surgery, such as the corrected visual acuity before surgery, and the above can be achieved after surgery. If the corrected vision before the surgery is only, it will not be achieved after the operation, only is. The surgery only changed the method of wearing glasses, not to address the nature of myopia.

Corrected vision before surgery is not good, and vision after surgery will not be good. Myopia eye surgery requires normal or higher corrected visual acuity and stable power before surgery.

Myopia eye surgery has simply changed the way to wear glasses. The surgery is to make the lens on the cornea, or implant the lens into the eye key closure to achieve the purpose of information search to correct vision.

After myopia eye surgery, you should use your eyes correctly, avoid excessive eye use, develop good eye habits, and avoid further increase in power and further decline in vision, resulting in vision regression.

Everyone's vision is different, and the vision that can be restored from myopia surgery is also different. Generally, how much you can correct your vision with glasses will recover after myopia surgery.

However, this corrected vision is foot correction vision, and many people wear glasses that do not match their myopia degree, so self-corrected vision is generally not up to the best so this corrected vision depends on the corrected vision during the hospital examination.

Just like before I had myopia surgery, I could barely reach the monocular vision with glasses, but when I did the preoperative examination in the Taixue Ophthalmology Department of Suzhou BenQ Hospital, Zheng Ayuan's check, the visual acuity was checked in detail, and the corrected vision measured by the doctor was that my vision was really restored after the operation.

The best thing to do at the moment is to have surgery... Table tennis can be relieved, take your time to find ,,, without glasses...

At present, in addition to wearing glasses, the only way to correct vision is surgery.

What else can I do to restore my vision other than laser surgery? How does Xiao Li Feidao practice eyesight? Staring at the candle flame for two hours a day, you can hold on for 20 minutes.

After an hour of sitting down to study, playing on the computer, and watching TV, I stood up and looked into the distance. Then you can massage the Hegu acupoint. You can also often close your eyes and turn 10 turns left and 10 turns right - not too much, too much is tiring.

Doing more sports such as badminton and table tennis can make the eyeballs see far and close for a while, and restore the elasticity of the ciliary muscle.

1. Distant gaze:

Find a grass or green tree 10 meters away: due to its short wavelength, green imaging is in front of the retina, which promotes the relaxation of eye accommodation, relaxes the ciliary muscles, and reduces eye fatigue. Don't squint or blink all the time, distract from distractions, concentrate and gaze intently for 25 seconds to identify the outline of a blade of grass or a leaf.

Then place the palm of your left hand slightly above the front of your eye 30 cm and look at the palm prints from beginning to end for about 5 seconds. After looking at the palm prints, gaze at the grass or leaves in the distance for 25 seconds, and then look at the palm prints. Repeat 20 times in 10 minutes, three times a day, and increase the number of training times if your vision declines severely.

2. Crystal manipulation.

Blink of an eye: Put your hands on your cheeks and turn your eyes 10 times in the order of up, down, left and right, then 10 times counterclockwise and 10 times clockwise.

Find a scene 3 meters away (e.g., calligraphy and paintings on the wall, etc.), raise your left hand slightly higher than your eyes (about 30 cm), see the palm and hand lines, and then see the distant object, and move your gaze between the two as quickly as possible, 20 times back and forth.

3. Massage exercises.

In either a seated or supine position, the eyes are naturally closed, and the acupressure points around the eyes are massaged sequentially. It is required to take the acupoints accurately, the technique is gentle, and the local soreness is the degree.

1 Rub the Tianying acupoint: Gently rub the Tianying acupoint with the thumbs of both hands (below the eyebrows, at the upper corner of the outer orbit).

2 Squeeze the eye acupoint: Use the thumb of one hand to gently rub the eye point (the base of the nose is close to the inner canthus of both eyes) and press down first, then squeeze it upwards.

4. Press the temples and wheels to scrape the eye sockets: press the temples with your thumb (the middle of the eyebrows and the outer corner of the eye is a horizontal finger backwards), and then use the curved index finger to gently scrape the inner side of the second section of the eye socket, from the inner upper > outer upper to > outer lower > inner and lower points, so that the acupuncture points around the eye sockets such as the bamboo fish waist, the silk bamboo space, the pupils, the ball queen, and the weeping are massaged. It is beneficial for pseudomyopia, or to prevent the deepening of myopia.

If you are a junior high school student, you only need to know that the image of distant objects is in front of the retina, and to correct myopia, you need to make the light diverge appropriately, so you need to use a concave lens to correct it. See diagram below.

Actually, as long as you are not a professional doctor.

That's a lot to know. But to understand laser correction of myopia, it is necessary to understand a little bit about the eyes
