Omega-3 for your eyes
Research finds DHA may help preserve your vision.
The omega-3 fatty acid known as DHA is touted for its many health benefits, and vision protection may be one of them. A new study published in Investigative Ophthalmology & Visual Science found that DHA, one of three forms of omega-3 fatty acids and the substance that makes up about 30% of brain matter, prevented age-related vision loss in lab mice. DHA is considered the most complex form of omega-3, but is among the most difficult to consume in sufficient amounts because it is contained in so few food sources.
Dr. Ann Bajart, a corneal specialist and clinical instructor in ophthalmology at Harvard Medical School, says the vision study likely applies to humans.
