Your situation is exactly the same as mine. This symptom is medically called ptosis. This is a kind of myasthenia gravis. This can be operated. Go to plastic surgery. I had two operations, the first was three years ago, and the second was on the 8th of this month. But it is still not as big as the right eye, but it is much better than before the operation. For example, 2,000 to 3,000 yuan for surgery will do. Because the fees vary from place to place, mine was done in Guangxi Medical University, and the operation fee was 1680 (excluding the medicine fee and the suture removal fee, but it didn't cost much). There are two surgical methods, which can be found by inputting ptosis online. Kenichi, go to the hospital. It doesn't cost much to take a look with a number. I wish you become a confident person.
