​

Answer 1

Answer:concave lens

Explanation:Myopia treatment

Nearsightedness can be corrected with eyeglasses , contact lenses or refractive surgery. Depending on the degree of your myopia, you may need to wear your glasses or contact lenses all the time or only when you need very clear distance vision, like when driving, seeing a chalkboard or watching a movie.

Answer 2

Answer:

To correct the myopia the person concerned should use concave lens of focal length (f) = -80 cm = -0.80 m

Power of lens (P) = 1/f(m) = 1/-0.80 = 100/-80 = -1.25 D.
