Diopter correction for M240. To achieve diopter correction for your M240, a simple yet effective solution is to use a pair of old prescription glasses. The next step involves carefully cutting the prescription lenses to fit perfectly into the designated parts. Once you have successfully inserted the lenses into their respective slots, it's time to mount them onto the eye cup of your M240. The prescribed thickness for these prescription lenses is crucial, with a minimum requirement of 1.8 millimeters and an optimal range of up to 2 millimeters.
