Post op refractive surgery patients frequently have the problem of glare during night because the pupil size increases in the dark and the edge of the flap raised during surgery comes in the line of vision and causes the glare. If the problem is too much, you can consider using topical medication to reduce pupillary size before going to watch movie etc. but that can’t be prescribed without baseline evaluation

Generally due to dryness ! Use topical lubricant eye drops and If the problem persists pls visit a ophthalmologist
