I have used cholecalciferol oral solution spray in my eye for 30 times unknowingly.
Thanks for your Question
First of all you have to stop using that. Second thing try to use preservative free lubrication every 2-3 hours for few days. Most likely this medication can cause eye irritation with foreign body sensation and dry cornea.
In case you have red eyes and/or blurred vision, you have to visit your eye doctor.
