Focus Night & Day (6) (119)
A popular and good lens for people who want to avoid removeing lenses at night. Night & Day lenses can be used around the clock for up to one month, however they do not fit all eyes. Always follow your optician’s recommendation. Due to its silicon-based construction, this lens allows the passage of much oxygen to the cornea. (Insufficient oxygen passage can readily cause eye irritation.) Diameter 13.8
