This trial compares two types of artificial lenses (EDOF and monofocal) to see which gives better vision after cataract surgery combined with removal of an epiretinal membrane, a thin layer of scar tissue on the retina. The study aims to find which lens may improve how clearly you see at different distances.
This study tests whether special light-emitting glasses can help reduce symptoms of depression in people on long-term hemodialysis. You would wear the real glasses or a placebo pair for a set time each day, while the research team monitors your mood.
This trial tests whether special filter lenses can help prevent migraine attacks. You would need to come to the clinic during an untreated migraine attack. It is for adults under 66 who have frequent migraines (at least 4 per month) and no other chronic pain or eye conditions.
This study compares FL-41 tinted spectacles with special contact lenses to see which better reduces light sensitivity (photophobia). Participants will try both types and report their comfort.
This study compares two types of glasses (single-vision vs. progressive lenses) to see which one helps people with aging-related reading difficulty (presbyopia) see better and feel better in daily life.
