My husband and I both have an inner pair and an outer pair. Ironically, my husband's right eye is not good, and neither is his left eye. It's a perfect match Haha ~ ~ ~ I think it may be that you look at the mirror closer by yourself, so you look very carefully. I have been with my husband for 4 years, and this year I discovered that his eyes are one big and one small. I don't see anything wrong either.
If you really care, you can try several methods.
One is to cut double eyelids, but it will be obvious after a while, and the original double eyelids can also be made into single eyelids.
The second is to use double eyelid glue. This kind of glue is used before going to bed, and the single one is also glued in pairs, which can be used for a long time the next day. Of course, it can also be used during the day, as long as the technique is skilled, others can't see it. Use this for a while, and your double eyelids will be permanent. But the disadvantage is that it will make the eyelids droop. This is for my use.
There is also the use of double eyelid fiber, which I have never used, because it is not suitable for inner double eyelids, but it is suitable for single eyelids. You can also try.
In addition, it is recommended to trim your eyebrows. The natural one won't have obvious pruning marks, but it will make you look more energetic. Many barbershops have them. Just make sure what you want before you fix them.
