## Introduction to Power of Lenses. The Human Eye

How do people see the objects around them?

In weather forecasts there is an option called visibility. Do you think it depends by the ability of humans to see objects around them or by weather conditions? Why?

What do people use to see better when they have sight problems? Why?

Are all optical glasses identical? What do you known about them?

In this tutorial, we focus on the use of lenses in sight correction. For this, we also need to explain the human eye as a natural optical tool. Hence, some elements contained in biophysics involving nerves, eye-parts, etc. are discusses as well. Lenses, Equation of Lenses and Image Formation of Lenses
