Trig and Optometry

What is the most common thing that we use trig in our life?Yes it is GLASSES

How does the glasses work?

For nearsightedness, glasses correct the problem of the eyeball being too long to focus upon a far away image projected onto the retina. The glasses offer a concave lens that bends light rays outward, which normalizes the eyeball. In farsightedness, the eyeball is too short to focus upon objects that are near. Glasses use a convex lens that bends the light inward before it reaches the eye's lens, thereby correcting vision.
