What is focal length of a lens?

The focal length of a lens is the distance from a lens to the focal point of that lens.

It is a measure of how strongly a lens converses or diverges light.

The power of a lens is the inverse of the focal length when given in metres.

Power of a lens = 1/focal length (m)

The focal length = 16.7 mm = 0.0167 M

Power of lens required = 1/0.0167 = 59.9 diopters

Therefore, the lens strength or lens power of contact lenses that m should be prescribed to correct the nearsightedness is 59.9 diopters.
