There is no absolute answer to which eye should be the dominant eye, because everyone's situation is different. Generally speaking, if you are used to judging the distance by what your left eye sees, then your left eye may become your dominant eye. And if you are used to judging the distance by the image you see in your right eye, then your right eye may become your dominant eye.
Here are some suggestions on how to restore the sense of distance between dominant eyes:
1. Do more monocular exercises: Exercise your dominant eye and improve your sense of distance by reading books, reading maps and recognizing signs with one eye.
2. Maintain good eye habits: avoid excessive use of eyes for a long time, and take a break every once in a while to give your eyes a full rest.
3. Do more outdoor activities: Outdoor activities are very helpful for vision recovery and distance recovery, because sunlight can stimulate the retina to secrete dopamine, which is helpful for eyeball development.
4. Consult a professional ophthalmologist: If you feel that the dominant eye has poor vision for a long time, I suggest you consult a professional ophthalmologist for more treatment methods and suggestions.
As for the problem that you mentioned that the sense of distance becomes worse after wearing glasses, it may be because the glasses are not suitable or the lenses are faulty. It is recommended that you re-optometry and choose appropriate glasses to ensure the accuracy of glasses. At the same time, we can try to replace different types of lenses, such as progressive lenses, in order to better adapt and improve the sense of distance.
In short, although we can't completely change the dominant eye, we can improve our vision and sense of distance through some methods to minimize discomfort. Please consult a professional ophthalmologist if necessary.
