Word of the Week: Sclera

Today’s word is:

sclera 

Pronounced: SCLARE-uh

Sciency Definition: The white, fibrous tissue that covers all of the eyeball except the cornea.

Or I could have saidEyeball.

What’s it do? The sclera gives the eyeballs their shape and protects them from damage when your 4 year old pokes your 2 year old in the eye just to see what happens. The muscles that control the movement of the eye also attach to the sclera, and the sclera also keeps all the important organs of the eye in place so our depth perception and focal abilities remain intact. (Did you know that eyeballs have organs?)

Example sentence: Don’t fire until you can see the sclera of their eyes!
