A study comparing different types of contact lenses found that daily disposable options cause less damage to the ocular surface and less increase of proinflammatory cytokines as compared with reusable options.

Seventy-one individuals who had not previously used contact lenses were randomized to wear for 3 months daily disposable hydrogel contact lenses (group 1), daily disposable silicone hydrogel contact lenses (group 2) or reusable silicone hydrogel contact lenses (group 3). All subjects were told to wear their contact lenses every day for approximately 10 hours.
