Contact lenses work very similarly to glasses in terms of repairing vision. They are magnified lenses that enlarge everything in sight. Lenses are shaped to conform to the shape of your eyes. Once patients who wear them get comfortable wearing them, they shouldn't even notice they are in. Special lenses are made for those with irregularly shaped eyes (astigmatisms, toric lenses). These are supposed to fit better and not fall out or get irritated as often.

Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
No they do not. Transitions cannot be tinted because it will not be effective. However, Polarized lenses can be tinted darker.
Microscopes use two main types of lenses: objective lenses and eyepiece lenses. Objective lenses are placed near the specimen and magnify the image, while eyepiece lenses magnify the image further for viewing. These lenses work together to produce a magnified and detailed image of the specimen being observed.
The AF 'A' Mount Minolta lenses work on the Sony, also sigma and tamron do a range of lenses to fit Sony Alpha models.
Yes but older AF lenses that do not have an autofocus motor in them will not autofocus with the D5000.
Information on how camera lenses work is available from many websites. Among them are Wikipedia, eHow, How Stuff Works, YouTube, Photo Technique, and ePhotozine.
No, Canon lenses are not compatible with Nikon cameras due to differences in lens mounts and electronic connections.
Each system has different mount lenses and within each system you will have lenses compatible with a full frame sensor labelled different than in another system. Typically crop sensor work with all lenses within the system and full frame sensors work with lenses designed for a full frame sensor. Check with the manufacturer. For example with Canon: EF-S are lenses compatible with crop bodies, but NOT with full frame bodies. EF are lenses compatible with both crop and full frame bodies.
