Morning vs nighttime replacement affects adverse events with extended-wear contact lenses

Morning vs nighttime replacement affects adverse events with extended-wear contact lenses: For people using 30-day extended-wear/continuous-wear (EW/CW) contact lenses, replacing lenses at night doesn't lower the risk of complications compared to changing lenses monthly, suggests a new study. In contrast, replacing lenses every morning reduces the overall rate of "ocular adverse events."
