What is the result of using a lens that is too powerful for a person's vision?

Using a lens that is too powerful for a person's vision leads to increased strain and discomfort because the eye is forced to work harder to focus. When a lens has a higher prescription than needed, it can create visual distortions and make it difficult to see clearly. The eyes may experience fatigue as they struggle to adjust to the overly strong correction, leading to symptoms such as headaches or double vision.

In contrast, powerful lenses do not improve distance vision or enhance the clarity of near objects when they exceed the required strength. Additionally, the concept of decreased light absorption does not apply directly to how corrective lenses function; rather, it relates more to the material properties of the lens and its filtering capabilities.

Overall, the primary consequence of using an overly strong lens is the physical discomfort and visual strain experienced by the wearer.
