Pseudomyopia is a sudden or temporary myopia caused due to some ailments leading to increase in refractive power of the eye. The ciliary muscles develop a temporary spasm due to an ailment like say diabetes.
A concave lens should be used by a person suffering with pseudomyopia.
Generally, this defect vanishes when the ailment is cured. Hence, it is called a temporary myopia.
