Vitamin D seems to cure everything.

A new study suggests that supplementing with Vitamin D can prevent recurrent uveitis.

Tell me about this study.

A research team recruited 151 patients, 74 of which had active uveitis, while the remaining patients had inactive uveitis. The researchers measured serum vitamin D levels and asked the patients to fill out a questionnaire about their UV exposure and vitamin D intake.

What did they find?

Patients with active uveitis not only had significantly lower vitamin D levels than the inactive group, but they also had lower levels than the average population.

The take-home.

The authors state that, "vitamin D supplementation should be studied as an option for the prevention of uveitis relapse in at-risk patients."

Do yellow lenses really help my nighttime driving?

Not according to new research published in JAMA Ophthalmology. Investigators recruited 22 volunteers to operate a driving simulator both with and without yellow lenses. Of the volunteers, 18 were younger than 30 years of age and four were older than 70 years of age. The investigators tested the volunteers’ reaction time with and without yellow lenses and under a variety of conditions (very dark to bright oncoming headlights). They asked each participant to press the horn as soon as they saw a pedestrian.

What did they find?

"Yellow-lens night-driving glasses did not appear to improve pedestrian detection at night or reduce the negative association between headlight glare and pedestrian detection performance." (via)
