    Eleven of the 14 had measurable improvements in the vision of o...

    Blinking: It's About More Than Moistening the Eye

    Most folks think of blinking as the eyes' version of windshield wipers, clearing the eye of debris and maybe lubricating it, too.

    But blinking is much more than that, researchers report: It also helps the brain process what it's seeing.

    That's perhaps counterintuitive: Wouldn't it make sense to not blink, so eyes are receiving an uninterrupted stream of information?

    Do You Really Need to Fast Before a Common Cardiac Test?

    Prolonged fasting before an internal heart exam done under sedation may be unnecessary, new research suggests.

    Regret After Gender-Affirming Surgery Is Largely a Myth, Experts Say

    Despite a common belief in the medical community and elsewhere, the vast majority of people who undergo gender-affirming surgery do not regret it later.

    That's far lower than rates of regret about any kind of surgery among cisgender people (peo...

    Federal regulators are warning consumers to stop using eyedrops and gels from several major brands after finding unsanitary conditions in a manufacturing plant.

    No Evidence 'Blue Light-Filtering' Glasses Actually Help Eyes

    Heavy screen users often buy blue light-filtering eyeglasses to protect their eyes -- but they may be wasting their money, a new study suggests.

    A new research review suggests these blue light-filtering glasses probably make no difference to eye strain, eye health or sleep quality, at least in the short term.

    And it's still unclear whether these glasses protect against retina damag...

    Glaucoma: Spotting It Early Is Crucial

    Treatment can control the symptoms of the most common type of glaucoma and save someone's vision.

    The catch is that a person can't feel the changes in eye pressure that can damage vision, so they often won't know they even have it before it's too late.

    That is, unless they've been seeing an eye doctor regularly.

    One vision expert encourages people to not wait for that pressur...

    Low-Dose Eyedrops No Better Than Placebo for Nearsightedness Among Kids

    Low doses of the eyedrops ophthalmologists use to dilate your pupils during an eye exam are not able to slow the progression of nearsightedness (myopia) in children, a new clinical trial has found.

    Atropine eyedrops at a concentration of 0.01% did not outperform placebo drops in slowing either myopia progression or elongation of the eye among children after two years of treatment, the stu...
