This double-masked (subject and investigator), randomized, bilateral, crossover, direct refit study compared the clinical performance of two daily disposable test contact lenses (somofilcon A and stenfilcon A) when fitted to existing wearers of comfilcon A monthly lenses. After a month of re-useable lens wear in the comfilcon A lenses, subjects were randomized to wear each daily disposable lens type for one week.
