Oscars eyes normally stick out a bit however if the eyes are sticking out more than normal then this is probably pop eye. This is why a pic is needed

If it is pop-eye the cause is usually either a bacterial infection or fighting/injury (usually you only get it in one eye)

If the cause is bacterial then the cause is usually poor water quality. Can you test your water for ammonia, nitrite and nitrate and post the actual results. The treatment is to rectify the water quality (lots of water changes) and to add an anti-bacterial (some say treats pop-eye on the container)

If the cause is fighting then you need to stop this and that usually means separating the fish. The treatment is the same as mentioned

My fish keeping skills were not as good as they are now and i have had mixed success with treating pop-eye. I have had 2 deaths and one cured. Good luck
