Eye exercises can help relieve eye fatigue but they can't help improve your vision. I have nearsightedness too. I had tried eye excercises for about 3 months but I hadn't found any sign of improvement in the end. I suggest you to stay away from computers or TV. This can help prevent your eyesight from decreasing dramatically. Or you can wear a pair of computer glasses when you are playing computer games or working in front of a computer. You can do some eye exercise to relieve strained muscles around your eyes. They work just as herbal remedies or nutrients supplements in help maintaining the health of your eyes.
Dude, they can't help improve your vision but they can help relieve eye fatigue. After viewing the computer screens or reading a book for a long time, you can do some eye exercise to relieve the strained muscles around your eyes. This is good for your eyes. If you want to correct your vision problem, you can consult for an eye doctor for some good suggestions. I heard that Bate's vision therapy can help with vision problems but it is very expensive, so not all people can afford it. And there is a kind of surgery that can help correct some vision problems. You can consult for more details if you want to apply for it. Good luck!
