Computer graphics are meant to be perceived through human eyeballs. So we can count on the eyes continuing to blur point lights whether you're looking at a screen or at outer space.

It's not that simple. Computer graphics are (currently) displayed on a flat 2D plane at some single distance from the eyeball. Typical vision defects affect different distances differently. Think "reading glasses" vs "driving glasses".

Also, the game might be simulating an experience from a character's point of view, and expect the player to be wearing glasses to correct their personal vision defects (to the extent possible).
