What is a possible consequence of not having lenses properly centered?

Not having lenses properly centered can lead to a higher chance of developing eye strain. Proper lens centering is crucial for ensuring that the optical center of the lenses aligns correctly with the pupil of the wearer’s eyes. When this alignment is off, the individual may have to adjust their head or eye position to see clearly, resulting in unnecessary strain on the eye muscles.

This strain can manifest in various symptoms, including discomfort, headaches, and visual fatigue, particularly during extended periods of use. Hence, proper lens centering is essential for maintaining visual comfort and eye health.
