Eye Drops

Eye Drops, referred to in game as "The World's Finest Eye Drops", are an item in the Ocarina of Time Trading Sequence.

Location and Uses
If Link brings the Broken Goron's Sword to Biggoron on Death Mountain, he will say he will not be able to repair it because of his irritated eyes. Later on in the Trading Sequence, Link will receive the Eyeball Frog, which can be made into Eye Drops by the Lake Scientist. Since the Eye Drops don't contain any preservatives, Link must bring them to Biggoron within a four-minute time limit. If Link can successfully bring the Eye Drops to Biggoron before they expire, he will give Link the Claim Check.
