  • &NA; Looking through optical instruments stimulates the eye to accommodate more than would be necessary for naked eye viewing; this increased near power is called instrument myopia. The amount (up to ‐5 diopters) varies with the observer and the conditions of viewing. Using microscopes produces ‐1.5 to ‐2 diopters of instrument myopia. More instrument myopia is found with low‐power magnification, inexperienced users, and when focusing from minus blur to sharp image. Physiologically, the… CONTINUE READING
