Eye injuries should be examined by a veterinarian right away. The fact that you can see a discoloration on the eye is a good indicator that there is damage there and that can become a very serious issue in a matter of a couple of days. This is because the cornea (outer layer of the eye) doesn't have good blood supply so the body's white blood cells that normally speed to an area to fight off invading organisms such as bacteria or fungi cannot get to these wounds on the cornea right away. It takes several days for blood vessels to grow out to the damaged area so that the body can effectively fight infection and heal the area. In those days, the fungi and/or bacteria that have contaminated the area have pretty much free rein to multiply and continue to damage the area. It only takes a matter of a few days for a simply corneal scratch or abrasion to be so damaged by invading organisms that it ulcerates completely through the cornea. Topical medications should not be applied without first having an exam. Certain topicals can actually make matters worse. And besides topical antibiotics or antifungals, there are other drugs that should be used to help aid healing and decrease discomfort associated with eye injuries.
Get a vet out to examine the eye and treat it right away.
