When you think about it, every time you look at a character in a video game, you're looking at them through a lens. Your eyes project onto the screen, and your imagination creates a mental image of what you're seeing. If you're doing it right, this mental picture will be more or less accurate.

Grimsy Enhanced Eyes by Grimsy is a mod that makes the eyes of characters more vivid, sharper, and more natural.

It also helps to fix the lashes of characters. This means that when you look at a character in a video game, your eyelashes will stay in place instead of fluttering around.
