Document Summary

Question 1: look at the picture of the eye there does not seem to be much refraction between aqueous humor and lens. This is due to the fact that the indices of refraction of humors and lens are very similar. Types of vision: typical eye can focus objects as close as 25cm called near point , far point is the furthest object the eye can focus clearly, common types of vision include myopia and hyperopia. Question 2: bring an object near your eye until it starts to look blurry. Estimate your near point (remember back the physics optic lab). Below 15cm normally but can be different. Question 3: what is the farthest object you can resolve before things get blurry; identify your far point. Different for each person but the majority said above 5m. Question 4: which of these types of conditions describe your vision.
