SofLens One Day lenses are daily disposable lenses that are thrown in the trash every night after one day of use. Daily disposable lenses guarantee that calcium deposits or proteins will not bind themselves to the lenses and irritate your eyes, making Bausch and Lomb SofLens One Day lenses ideal for anyone new to wearing contact lenses. SofLens One Day lenses are also made with a light blue tint to help you locate the lenses in the solution.
