I've worn contacts for the last 17 years, this year I've started to get halos and blurring around text and when objects are illuminated from behind in low light conditions, think pub. Now I do not get this when wearing glasses. I think it can either be: Dry eyes causing this effect Or My pupil is larger than the optical zone in the contact lens. My optician said I might just need to live with it, but I don't accept that. I'm -8.5 d in both eyes in contact. . Has anyone else overcome these issues or do you know where I can find contacts with a larger optical zone?
