how long does it usually take to go heal??? and do i NEED to visit my eye doctor? i saw somewhere to stop wearing contacts until it heals so i took them out wearing an old pair of glasses.

i was helping a welding build a railing on a deck in the field and i was holding the pickets for him and figured looking away was enough well we did about 100 tacs that day and i came home and my face felt a little sun burnt and the bottom corner of my eye was red. it looks worse now. i have very little discomfort in my eye except for when i wake up and nothing abnormal with vision no spots or anything like that. BUT i am wearing my hood now when i help, eyes are very important and i'd like to protect what little eye sight i have left.
