Answer:  Refraction

                Phoropter

Explanation:

Refraction (refractive power): As light enters the eye, the lens helps focus light rays so that they come to a focus on the retina. This action is called refraction.

An instrument called a phoropter detects the eye’s error of refraction.

In my personal experience In order to stay fit I do ballet and tennis. Those two things have helped me stay healthy and fit as well as creating hobbies! I also want to mention that I take vitamin supplements just in case if I am not for filling my normal vitamin intake from foods. So for example I take some vitamin C powder! I think it’s extremely important to work on your health and your physical activity because later in life all these things will affect you in a positive way so you won’t have to worry too much of your health considering the fact that you have been working on your health for the past years. I’ve also read that eating healthy can help you age backwards so you’ll look much younger at the age of 50 then you would if you didn’t take care of yourself physically. <3 have a great day

Why do you think that a class called "Physical Education" is a mandatory class for a person your age? You need to write 5 senten
rosijanka [135]

I think its mandatory becuase at our age, we're going through hormonal changes and hella body changes. We're gaining weight, losing it and staying fit and healthy is mandatory to be able to maintain that. By gaining too much weight at a young age, you can cause many future health problems. don't get me wrong, every body is beautiful and everyone was born different but we just need that little bit of exercise to keep our blood pumping and keep up healthy.
