Q: How to measure optical lens thickness?
A: Glance at the lens and decide of your house thicker on the edge or in the center. Lenses for nearsighted people will be thicker on the edge. Lenses for farsighted people will be thicker from the center.
Opt for the kind of caliper make use of. To measure center thickness, use an external caliper, a caliper with protruding pinchers. To measure edge thickness, a clamping-style caliper is fine best.
Clamp the caliper onto the thickest location before the pinchers or clamps barely touch either side with the lens.
Look at measurement for the caliper. It will be displayed on a dial or even a marker within the caliper.
