Clear vision is essential for everyday life, yet our eyes can develop certain defects that affect the way we see. This video/lesson explains all major defects of human vision in a simple and detailed manner to help Class 10 CBSE & ICSE students and competitive exam aspirants master the topic for exams.

We cover:

Myopia (Short-Sightedness): Why distant objects look blurred, its causes and correction using concave lenses.

Hypermetropia (Long-Sightedness): Why near objects look blurred, its causes and correction using convex lenses.

Presbyopia (Age-Related Long-Sightedness): How weakening of ciliary muscles and lens flexibility leads to difficulty in focusing, and how bifocal or progressive lenses correct it.

Astigmatism: How irregular curvature of the cornea/lens distorts images, and how cylindrical lenses help.

Cataract: Clouding of the eye’s natural lens, reasons behind it and its treatment by surgical lens replacement.

✨ Why watch/read this?

Clear, exam-oriented explanation with diagrams.

Covers definitions, causes, symptoms and corrections for each defect.
