Why do your eyes get smaller?

When a person's eyes grow into an adult, they will no longer show major changes. If the eyes become smaller, especially the black eyeballs, there are probably the following conditions: First, pterygium grows, which is a kind of conjunctival degeneration. Degeneration mainly occurs from the conjunctiva in the inner canthus, and then climbs up the cornea, which will severely block part of the cornea, making the black eyeballs appear smaller. In this case, surgical resection is required. There is also a situation that people will show skin relaxation when they are old, and the skin of the eyes is the same. After the skin relaxation, it gradually covers the eyelid fissure, and it will also look like the eyes are shrinking. This situation can be changed through plastic surgery.
