Progressive Lens - Miscellanea

Miscellanea

• For those new to progressive lenses, an accommodation period is often required because the brain needs to learn to adapt to them. This period varies from a few hours for some individuals up to around two weeks. During this period, side effects can include headache and dizziness. It is advised that, when these symptoms set in, the progressive lenses are removed for a short period and replaced after symptoms have subsided. Returning to an older prescription or different type of lens design (bifocal, trifocal) only serves to increase the adaptation period to the progressive lenses.
• Depth perception and distance estimation can be influenced during the adaptation period.
