Of course. If you know you have narrow angle glaucoma, you probably have had the diagnosis made and the treatment (laser peripheral iridotomy) already administered. There is no relationship between these features and the ability to wear contacts. So if that is your wish, discuss with you ophthalmologist to get the proper design and fit.
Yes. People who have glaucoma can utilize contact lenses. However when patients do use drops in order to treat their glaucoma , they need to be aware that they need to remove the contact lenses when putting in eyedrops and wait at least 15 minutes before putting them back in. This prevents the preservative with in the eyedrops from getting into the contact lens.
