Should I use my glasses or contacts all the time?

You generally don’t need to wear glasses or contacts constantly; use the correction that gives you clear, comfortable vision. Contacts are an option for daily use if you tolerate them and follow safe-wear practices.

• Daily tolerance and eye surface: Most people—especially when younger—can tolerate soft contacts, although contacts alter tear-film dynamics and reduce oxygen reaching the eye’s surface. Tolerance can decline with age or dryness, so it’s reasonable to cut back if they become uncomfortable. 1 2
• Vision quality: Contacts may give some people sharper or higher-quality vision than glasses because a smooth contact lens can correct certain higher-order optical aberrations that a glasses prescription cannot. 3
• Hygiene and safer use: Follow the recommended cleaning and wear instructions, and don’t sleep in contacts unless specifically directed. Daily disposables are recommended as a safer, simpler option; poor hygiene or overuse can raise infection risk. 4
• Sunlight and circadian timing: You can wear prescription glasses or contacts while viewing sunlight for circadian entrainment; corrective lenses focus light onto the retina. 5 6
