Lenses

 

The ability to focus light comes from the use of lenses. Lenses function based on the property of refraction.

Refraction: the bending of light as it passes from one material into another



WOW! How can this amazing property be harnessed?

By changing the shape of the glass of course!



A shooter will always be looking through at least one lens while shooting. This is the lens in the eye. In addition, many people need to wear a corrective eyeglass.

It is the nature of lenses to have the clearest vision straight through the center, so it is important to have the image and lenses aligned for the best view.
