    Induced hyperopia (farsightedness) using concave lenses significantly lowered intelligence test performance in subjects, especially with higher lens powers. These findings are relevant for understanding hyperopia symptoms and vision screening.

    Area of Science:

    • Ophthalmology
    • Cognitive Science
    • Optometry

    Background:

    • Hyperopia, or farsightedness, can affect visual acuity and potentially cognitive function.
    • Understanding the impact of induced refractive errors is crucial for vision science.

    Purpose of the Study:

    • To investigate the effect of induced hyperopia on cognitive performance.
    • To evaluate the applicability of induced symptoms to natural hyperopia.
    • To inform hyperopia prescription and vision screening guidelines.

    Main Methods:

    • Induced hyperopia in 42 participants using concave lenses of 1.00, 1.50, and 2.00 D.
    • Administered a standard intelligence test to assess cognitive performance.
    • Documented symptoms experienced by participants.

    Main Results:

    • A significant decline in intelligence test performance was observed with the highest lens power (2.00 D).
    • Induced symptoms correlated with those experienced by individuals with natural hyperopia.
    • The study provides evidence for the impact of hyperopia on cognitive tasks.

    Conclusions:

    • Induced hyperopia, particularly at higher diopters, can impair cognitive performance.
    • The experimental model effectively simulates symptoms relevant to clinical hyperopia.
    • Results support the need for accurate hyperopia correction and refined vision screening protocols.
