Most of us assume we see the world more or less the same way everyone else does. The same colors. The same clarity. The same sharp edges. History suggests otherwise. For many famous people, the world was blurred, doubled, dimmed, or slowly fading, even while they were shaping how the rest of us would see it.

This is a short challenge about that mismatch. Some of the pairings will feel obvious. Others will surprise you. Match each person to the eye condition or visual quirk that shaped how they saw the world, and in a few cases, how the world saw them in return.

You’re on the clock. Click a person, then click the matching eye condition or quirk.
