Dr. Amanda Redfern, an ophthalmologist at Oregon Health & Science University’s Casey Eye Institute, strongly advises against sleeping in contact lenses, calling it 'real bad' and likening it to 'Russian roulette.' She explains that this practice can lead to corneal ulcers, infections, and permanent vision damage. Even brief naps with lenses on pose risks, as bacteria can become trapped between the lens and cornea. Redfern emphasizes that no amount of time with lenses in during sleep is safe, urging users to remove them before resting.

The doctor also warns against exposing contacts to non-sterile environments, such as swimming or showering with them. Contaminated lenses can introduce harmful microbes, increasing infection risks. She advises against using tap water to clean or store lenses, as it lacks the preservatives needed to prevent bacterial growth. Redfern stresses that compromising lens hygiene—even temporarily—can result in severe complications, including corneal scarring that may require transplants.

For those who forget lens solution while traveling, Redfern refuses to endorse either sleeping with lenses or using tap water. She recommends discarding the lenses and going without for the duration, accepting temporary blurriness over risking eye health. Her guidance underscores the importance of prioritizing sterile conditions for contact lens use. Additionally, she dispels myths, such as the belief that reading in the dark harms vision, while highlighting the need for eye protection during hazardous activities.

Redfern’s warnings align with broader eye health initiatives, as 80% of learning relies on vision. Her insights, shared on HuffPost’s 'Am I Doing It Wrong?' podcast, aim to educate listeners on avoiding preventable eye injuries. She also advocates for regular use of protective eyewear during DIY projects, citing the high incidence of trauma cases she treats. By avoiding common pitfalls, individuals can preserve their vision and reduce long-term healthcare costs.
