Disadvantages of glasses

Need to re-adapt to new glasses

When the glasses were damaged, the glasses were not replaced in time. As a result, the nearsighted person wears old glasses and continues to look at things. The old glasses have 'remodeled' the eyes in the long-term process, and the eyes have adapted to the old glasses. Therefore, even if the power of the new glasses is the same as that of the old glasses, the new lenses will feel brighter. In this case, eyes produce uncomfortable symptoms. It is recommended to use the new glasses early the next morning. After a night's rest, the eyes will be easier to adapt to the new glasses. After a few days of continuous wearing, the dizziness symptoms will disappear.
