Pseudomyopia can be relieved with which type of lenses?

Pseudomyopia, also known as temporary or false myopia, typically occurs due to excessive accommodative spasm, which leads to difficulty focusing on distant objects. In this condition, the eye appears to be myopic (nearsighted), but this is not due to a structural issue with the eye itself; rather, it is a temporary situation often caused by prolonged near work or visual stress.

The use of plus lenses can help alleviate the symptoms of pseudomyopia by relaxing the accommodative system. Plus lenses increase the focal distance, making it easier for the eye to focus on distant objects without straining. By reducing the workload on the ciliary muscle, which controls accommodation, plus lenses allow for a necessary break and can help restore normal focusing ability.

In contrast, minus lenses would exacerbate the issue by further encouraging the eye to focus on near objects, cylindrical lenses correct astigmatism rather than addressing accommodation issues, and single vision lenses may not necessarily have the adequate power to relieve the accommodation spasm associated with pseudomyopia. Thus, plus lenses are the appropriate choice for managing this condition.
