your symptoms of blurred vision burning eye redness and sensitivity to sunlight are of concern. there are several conditions that can cause symptoms similar to yours. you mentioned that you wear contact lenses. one common condition related to dirty contact lenses or lenses that don't fit properly that doctors see is a corneal abrasion (scratch on the cornea). it would be best for you to get an eye exam by a doctor or an eye specialist immediately to help determine the exact cause of your eye symptoms. take care.
my right eye started bothering me today with a burning sensation. took contact out no help. still blurry with glasses. my eye has been burning all day. i washed my eye with buffered eyewash no help. i put my glasses on after taking my contacts out and my right eye was still blurry with everything looking somewhat doubled. it began about 12 hours ago and my eye is still visibly irritated bloodshot watering and burns particularly when i close my eye. also every time i went outside into the sun the my eyes(both) began watering heavily and the sun felt considerably brighter than normal.
