In general, squinting can see more clearly than staring, which is related to the optical principle. It can be understood that under the condition of a certain amount of light, expanding the receiving area will inevitably lead to blurred imaging.

Don't be nervous, because it is due to the self-protection reaction of the eyes, such as tears and blurred vision. Eyes are very sensitive. You don't think the eyelids are too swollen, but the eyeball pressure is quite high, hehe.

I wish you a speedy recovery ~ ~

This should have nothing to do with cutting double eyelids. The biggest possibility is this: after you cut your eyelid, it swells up badly, pressing the eyeball, slightly deforming the radius of the eyeball, and making the projection of the eye on the retina deviate, so after wearing glasses, things are blurred and double images appear. When you stare at your eyes, the eyelids exert more pressure on the eyeball and deform more, so the situation is aggravated.

I suggest you apply cold water to your eyes to help reduce swelling. Usually reduce the time of reading and watching TV, and reduce eye fatigue. It usually takes half a month to fully recover.

I hope it helps you.
