Eye Chart

The Eye Chart is a tool used by ophthalmologists, to determine if someone's vision is working or not.

Since it's first appearance it has been used as a decoration in some levels. This object can be thrown but it won't deal any damage. Besides not being equipped by the doctor, it is still considered a medical equipment.

Trivia

 * In later games the letters in the Eye Chart were removed because the developers wanted to avoid putting written words in objects. The are still some objects with letters that can be found in-game.
