The time it takes to get used to a new pair of glasses can vary from person to person, but generally falls within this time frame:
Initial Adjustment: Most people adjust to a new gradation within a few days, usually 2 to 7 days. During this time, it is normal to experience mild discomfort such as headaches, dizziness, or a distorted perception of objects.
Full adaptation: In some cases, adaptation may take up to two weeks, especially if the new prescription involves a significant change, such as a marked increase in lens power or switching to multifocal or progressive lenses.
Factors that influence adaptation:
Lens Type: Progressive, bifocal, or trifocal lenses may take longer to get used to than single vision lenses.
Significant changes: If the gradation change is very large, it may take a little longer to adapt.
Frame Style: Changing your frame style, especially if it changes the size of the lenses or their placement on your eyes, can affect your adaptation time.
Tips for easier adaptation:
Wear your new glasses regularly, even if you may feel discomfort at first.
Avoid switching between old and new glasses during the adjustment phase, to allow your brain and eyes to get used to the new prescription.
