Eye Test Game
A new patient has arrived. They say:
"I believe that my vision is close to normal."
Your goal is to determine the corrective lens prescription they need. You have 45 seconds.
Remember the sign convention:
- Myopia (short-sightedness): The eye's focusing power is too strong. This is a positive (+) eye error and requires a negative (-) corrective lens.
- Hyperopia (long-sightedness): The eye's focusing power is too weak. This is a negative (-) eye error and requires a positive (+) corrective lens.
