WebSep 12, 2024 · We can use the thin-lens equations to quantitatively examine image formation by the eye. First, we define the optical power of a lens as \[P=\frac{1}{f} \nonumber \] with the focal length f given in meters. The units of optical power are called “diopters” (D). That is, 1D=1/m,or 1m −1. Optometrists prescribe common eyeglasses and … WebSome Examples on Optics Formula are: Solved Examples Question 1: A short-sighted person can see clearly at a distance of 20cm. Calculate the lens power essential for the person to see as far as 60 cm? Solution: The power required for a far point of 60 cm is 1/f = 1/u + 1/v =1/60 – 1/20 =-2/60 1/f =-1/30 f=-30cm=0.30m Power D=1/f=1/0.30 hot and cold water dispenser faucet
