To determine the total magnification of any object viewed under your microscope you would... Multiply the magnifying power of the eyepiece by the magnifying power of the objective Most compound light microscopes have four objective lenses with magnification of 4X, 10X, 40X, and 100X. What magnifications are available if the eyepiece magnifies 15 times?
If you have astigmatism, youâll notice an axis measurement on your prescription. If you see an âaddâ on your prescription, that tells the optician that a person needs an added magnifying power added to the lens. They typically range from +0.75 to +3.00 diopters. So now when you see a slip of paper given to you by your eye doctor that reads. OD = -4.00 SPH + 3.00 add.
