New Research Suggests Taking Melatonin May Help Your Eyesight

What Is AMD?

AMD is an eye disease in people over 50, and it occurs when the macular, the part of the retina that controls straight-ahead vision, becomes damaged during aging.5 When this happens, blurry or wavy areas appear in central vision. Although AMD doesn’t cause complete blindness, it does make it harder to see faces and participate in activities such as driving and reading.

As of 2019, it was estimated that close to 20 million Americans were living with some form of AMD.6

There are two types of AMD: wet and dry. Dry or atrophic AMD is the most common, and it is caused by the thinning of the macula due to aging. Dry AMD usually progresses slowly through three stages: early, intermediate, and late. There is no treatment for late-stage AMD.5

Wet AMD, also known as advanced neovascular AMD, occurs when abnormal blood vessels damage the macula. This form of the disease progresses faster, and dry AMD can turn into wet AMD during any stage. However, unlike dry AMD, there are treatments available for wet AMD.5

How Could Melatonin Help with AMD?

The Case Western study didn’t explain why they think melatonin may be linked to a reduced risk of AMD, but another study on mice suggests that melatonin may help prevent retinal degeneration.7

The researchers with Case Western acknowledged that lifestyle factors, such as smoking and hypertension, may have influenced the findings, but they added that the results are solid enough for them to encourage further research.1

We spoke with a medical professional to see his take on this emerging research. Dr. Ben Mize, an optometrist with more than 30 years of experience, has not yet recommended melatonin to his AMD patients but states that he’ll consider recommending it once more in-depth studies have been performed. “Melatonin is accessible and affordable,” Mize added.
