See if you can't see clearly or part of it. I've been in this situation. Because I am weak in color, I am afraid of color testing. If I can't say anything, forget it. The problem is that I can see some pictures clearly, but I can't completely distinguish what numbers and pictures they are. That guess is really painful! Sometimes I know it's an animal, but I can't recognize it. I don't know if you are in the same situation as me. If you just can't recognize the specific numbers and figures sometimes, but you can recognize the color, and you have a general outline concept, it should be a weak color. This color weakness should be inherited from birth (it is not surprising that three generations have never had this disease, and my family has never had this disease for three generations. Am I infected? ), but it has something to do with the day after tomorrow (only a little). People with bad eyes are more likely to have bad eyes (because there are several people with bad eyes like me), so take good care of your eyes. As for the treatment ... there should be no way. Why not buy a picture book for physical examination and recite it yourself first? (A little self-deception) If you really want treatment, you can only go to a big hospital for consultation, but I find it boring. Spending a lot of money and energy may not be effective.
