Contact lenses are personal hygiene and optical medical devices. Please obtain a valid prescription from an eye care professional before your first purchase or power update. Wash and dry hands thoroughly before handling. 1-Day lenses are strictly single-use; 1-Month lenses require daily lens solution and must be replaced within 30 days. Avoid overwearing, and never wear lenses while sleeping, showering, or swimming. Discontinue wear immediately and consult an eye specialist if discomfort occurs.
