30:48 hypermetropia = (i) the focal length of the eye lens is too long, or (ii) the eyeball has become too small. Myopia = The eye lens becomes too convex or curved Depth of the eyeball is too much i.e. eyeball lengthened from front to back. When the length of the eyeball is too long as compared to the focusing power of the lens of the eye and cornea. Because of this, the light rays focus at a point in front of the retina and not on the retina itself. 57:05 Our eyes are most sensitive to yellow colors and are least sensitive to violet and red colors. Due to this reason school buses are painted yellow. As a result, the school buses can be easily identified by other drivers and a safe distance can be maintained to ensure the safety of children.

Myopia Reasons: Elongated eye balls (eye ball size increases due to genetic reasons) Excessive curvature of the eye lens. Hypermetropia Reasons: Eye ball size decreases (becomes small) The focal length of the eye lenght is too long. Presbyopia Reasons: Due to old age and arises due to the gradual weaking of the cilliary muscles and the diminishing flexibility of the eye lens. Can be fixed by, Myopia: convex lens of suitable power Hypermetropia: concave lens of suitable power Presbyopia: By surgical methods or by using bi - focal lens which consist of the upper part being concave lens and the lower part being convex. lens.
