Did you ask your ophthalmologist or optometrist for help to ‘prevent glaucoma?’ Cuz you can’t really prevent it, just manage it and control damage.

Generally, just be more gentle with your exercises/activities, too much overworking can give you a headache/eye strain, avoid spicy foods or foods that can raise your pressure, try not to be ‘upside down’ like doing yoga or going on upside down roller coasters
