The difference in pupil position between everyday use and various shooting positions can be overcome by a tailored pair of prescription glasses appropriate for action matches or field use. The optical center of the lens should match the pupil position behind a firearm, and lens area big enough for good protection. The temple tips should form a tight grip.

The lens should be made of polycarbonate for safety and tinted to enhance the sight picture. A properly tailored pair of glasses can reduce eye strain if not improve score.
