Answer 2

1. MYOPIA or NEARSHIGHTED. Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye.
2. HYPEROPIA or FARESIGHTED. This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it$.$
3. Astigmatism
4. Presbyopia
