Seeing Ultraviolet

Alek Komar had cataract surgery and now he can see the ultraviolet spectrum. Read about it here.

One of the more interesting aspects of the article to me details why this ability might offer an alien phenomenology of certain animals:

Komar’s case is interesting for multiple reasons. It’s a demonstration of how modern medicine can change what we think of as “natural” vision by altering the lens. It’s also a small window into how tetrachromats—animals with four types of cone cells—may see the world.

But then a surprise, the second half of the article goes into considerable detail about the color accuracy of LCD monitors.
