Control your prescription with contacts

The UK's Daily Mail (10/20, Hodgekiss) reports that children who wear overnight lenses, which "work by gently pressing on the cornea, reducing its curvature," may experience "far less sight deterioration than those who'd worn regular contact lenses." The Mail notes that US researchers are two years into a study, known as SMART, to test the overnight lenses in children. "Around 300 children aged eight to 14 are taking part in the five-year study," and after the first year, "the children in the overnight lens group had no prescription change; in the control group the average increase was 0.4 diopters."
