Medical specialists are issuing guidance on the safe use and hygiene of corrective lenses to prevent vision-threatening complications. 

Regarding contact lenses, experts warn that improper handling, such as sleeping in lenses, exceeding their intended lifespan, or using tap water for cleaning, can lead to serious issues including keratitis, corneal ulcers, and infections from microorganisms like Acanthamoeba. Recommendations include using silicone-hydrogel materials for better oxygen flow, opting for daily-disposable lenses, and maintaining strict hand hygiene. 

For eyeglasses, advice focuses on preventing physical damage. Common mistakes like using paper napkins or clothing to wipe lenses can cause irreparable scratches. Specialists suggest cleaning both frames and lenses daily using only cold water and neutral soap to remove sweat and bacteria.
