Objects viewed under a 5 diopter lens will appear 2.25x larger than normal. Its relatively simple to convert from millimeters to diopters. either by taking the reciprocal of the focal length. or referring to a simple table:
Enter The Value You Want To Convert (Dioptre (Diopter)).
337.5 ÷ 45.00d = 7.5 millimeters. It is all you need for radius conversion. Convert diopters to mm by using the calculator provided by specialeyes custom soft contact lenses.
Just Divide 337.5 By Either The Radius Value Or The Diopter Value And You Will Get The Answer You Are Looking For.
Converting the optical power to units of results in “diopters”. This is a conversion chart for dioptre (diopter) (optical). Where m is the magnification. d is the optical power in diopters and 0.25 is the reference distance in meters.
