Web1 f = 1 s + 1 s ′ In your situation this equation becomes: 2.75 m − 1 = 1 0.25 m + 1 s ′ This means we are taking an object at 25 c m, refracting the light through the 2.75 diopter lens and we are solving for s ′, the virtual image distance to which the 25 c m object is focused. This is the “non-normal” eye’s near point. http://physics.wm.edu/~labs/astro/astro_manual/ch8.pdf
