Lumigan (bimatoprost) is a prostaglandin analog eye drop used to treat glaucoma and ocular hypertension by reducing intraocular pressure. This medication works by increasing the outflow of aqueous humor from the eye, effectively lowering pressure that can damage the optic nerve and cause vision loss. For patients seeking affordable eye medications, working with qualified healthcare providers ensures proper diagnosis, appropriate monitoring, and access to authentic treatments with proper safety oversight for managing serious eye conditions effectively.
