SEEING THROUGH A LENS.  We see the world through lenses.  Eye glasses = lenses. Contact lenses = lenses.  Magnifying glasses = lenses. Microscopes.

Myopia (Nearsighted) Eyeball too long Distant objects focused in front of retina Image striking retina is blurred Correction: Concave lens or laser surgery.

Lenses Convex lenses converge rays of light. Parallel rays converge a fixed distance away from the lens. This is known as the focal length.
