Understanding Myopia and Hyperopia: A Guide to Short and Long Sightedness

The video tutorial explains common eye conditions, myopia and hyperopia, and their causes. Myopia, or short-sightedness, occurs when the image forms in front of the retina due to elongated eyeballs, making distant objects blurry. It is corrected with concave lenses. Hyperopia, or long-sightedness, happens when the image forms behind the retina due to compressed eyeballs, making nearby objects blurry. It is corrected with convex lenses. The video also covers the anatomy of the human eye, focusing on the lens and ciliary muscles, and how they help in focusing on near and far objects.
