What do iseikonic lenses aim to correct?

  1. Blurry vision

  2. Astigmatism

  3. Color vision deficiencies

  4. Unequal retinal image sizes

The correct answer is: Unequal retinal image sizes

Iseikonic lenses aim to correct unequal retinal image sizes, also known as aniseikonia. This occurs when the images projected onto the two retinas are not equal in size, leading to distorted or inconsistent vision. Options A, B, and C may be addressed by other types of corrective lenses, but they do not specifically target aniseikonia. Therefore, they are not the correct answer in this case.
