What effect does incorrect positioning of glasses have?

• A. Improved comfort
• B. Prismatic effect
• C. Better field of vision
• D. Stability of the lenses

Answer: (B)

Incorrect positioning of glasses can significantly lead to a prismatic effect. This occurs when the lenses are not aligned correctly with the center of the pupil, causing light rays to bend unnaturally. Instead of passing through the center of the lens, the light may hit the lens at an angle, resulting in visual distortions such as double vision or blurriness. This effect can impact the overall clarity of vision, making it difficult for the wearer to focus properly on objects. In contrast, proper alignment of glasses ensures that the lenses function as intended, thus providing clear vision without distortions. Comfort, field of vision, and lens stability are ideally enhanced with correctly positioned glasses. Misalignment can negatively impact these aspects, leading to discomfort or an inadequate visual experience.
