Diopters are inverse meters

Remember that 100cm = 1m.

conversely

Point of refraction

(meters)

(meters)

(meters)

(diopters)

Visual acuity equation

Note: 5Arcminutes = 20/20

Set up proportion:

Visual acuity (mm/metres)

Visual acuity (in/feet)

With text that we are familiar the brain may clear up that text more than our vision actually operates at.[1]

Average axial length accomodation/rate of change

If someone with typical eyes wanted to adapt say 20/20 to .25 less normalized within 3-4 months would need to decrease axial length 0.083mm about 0.92microns/day - 0.69microns/day average Credit: Mark Podowski
