Texas Rangers center fielder Josh Hamilton will play tonight and start against the Oakland A's after sitting out the last five games with vision problems, reports ESPN.com.

The Rangers said Hamilton has ocular keratitis, which is blurred vision from drinking too much caffeine and sports drinks, causing cornea dryness.

Hamilton left a game last week after telling Rangers manager Ron Washington he was having trouble seeing. Hamilton thought it was caused by a sinus infection.
