What type of lenses are typically prescribed to counteract pseudomyopia?

Pseudomyopia is a condition that often results from excessive near work or prolonged focusing at close distances, leading to temporary myopia (nearsightedness). In this situation, the eye's lens can become over-accommodated, making distance vision appear blurry. To correct this condition, plus lenses are generally prescribed.

Plus lenses are convex lenses that help to reduce the eye's accommodative effort for near tasks. They assist in relaxing the ciliary muscle responsible for focusing, thereby alleviating the symptoms of pseudomyopia. This corrective action allows the individual to focus more comfortably on distant objects and reduces the tension that causes the temporary myopia.

While single vision lenses may be appropriate for general vision correction, and bifocal or multifocal lenses serve different purposes for individuals who require assistance with both near and far distances, they do not specifically address the specific needs associated with pseudomyopia. The use of plus lenses directly targets the underlying accommodative strain, making them the optimal choice for this condition.
