In an era where screens dominate our daily lives, a silent epidemic is sweeping the globe. Digital eye strain, a condition ...

This is an image of a fluorescently labeled eye and surrounding tissue from a zebrafish. The blood vessels are purple (1), the lymphatic vessels are green (2), and the nuclei of all the cells are blue ...

The lens in the front of your eye focuses light on the retina in the back of your eye. The lens is like the one in a camera, and the retina is like film. The space between the lens and retina is ...

Scientists have discovered the oldest fossil evidence of insect larvae with highly developed eyes, revealing that some ancient larvae had advanced vision much earlier than previously thought. The ...

PG analogs lower the IOP by improving the outflow of fluid from the eye (pressure dependent and/or pressure independent drainage). Topical PG analog use is associated with iris color changes ...
