This study is designed to compare two eye drops, **Bimatoprost ophthalmic solution** and **LUMIGAN®**, in treating people with **chronic open-angle glaucoma** or **ocular hypertension**. Glaucoma is a condition where the pressure inside the eye, called **intraocular pressure (IOP)**, is higher than normal, which can damage the eye. Ocular hypertension means the eye pressure is high but hasn't caused any damage. The study will test if both eye drops are equally effective (this is called **bioequivalence**).

Participants must be 18 or older and have glaucoma or high eye pressure in both eyes. They will use the eye drops once each evening for 42 days and have check-ups to see how their eyes are doing.

• The study lasts for 42 days with regular check-ups.
• Participants must stop using other eye medicines before starting the study.
• Those who are pregnant or have allergies to the study drugs can't participate.

Before joining, participants will need to agree to follow study rules and provide informed consent, which means they understand the research and agree to be part of it.
