I use spectacles with a minus power of 4.75. Mostly ia have to be awake thoughout the night. From last few days there is a swelling above the upper eyelid, at first moment i thought its conjuctivities, but it wasnt because its not paining ot itching there. I'm not facing any eye pain but the only major concern is why its little swelling there above the upper surface of the eye lid. Please help
