4) You are performing a mission-impossible-style heist in a room filled with laser beams. You have to leave your eyes open so you can see. You have perfect distance vision. How do you minimize the damage of the laser beams on your retina? Answer this question by doing the below analysis.

A) Create a ray-tracing diagram of a laser beam entering your eye if your eye is fully relaxed (minimum optical power). CAREFUL: laser beam ray tracing is different than object ray tracing; for a laser, ALL of the incoming rays in a laser are parallel to the optical axis. (Hints: think carefully about where to put the focal points for your perfect distance vision.) B) Make a ray-tracing diagram of a laser beam entering your eye if your eye is tensed, at maximum optical power. Again, the beams are all parallel. (Key Hint/Question: Which way should the focal points move when the eye power is increased?)
