Do you mean that your eyes get bloodshot or that you see tiny red lines in the white of your eye? Or do you mean that a bit or all of the white part of your eye becomes red?
If the latter is the case (it sounds like it from what you say in your post), then that is called a Subcongunctival Hemorrhage and in plain english it means (roughly) that there is bleeding underneath the white of your eye. Now such a hemorrhage may be caused when one lifts heavy objects or sneezes or coughs a lot OR by more serious causes such as when a person has hypertension that is not controlled or is on blood thinners. Are you on blood thinners? Have you had your blood pressure checked recently?
Have you talked to your GP or internist about this? If not then it might be a good idea to call your doctor and let him know what's going on. Your doctor knows your medical history and he should be more than able to point you in the right direction here and to tell you how to deal with such episodes and what is causing them!
Here's a few links with information on Subconjunctival Hemorrhage:

There are so many possible reasons for the bleeding on your eyeball so you should have it checked out.
I had the same problem for a few months - it would happen every few days or so, along with bleeding under the mucosa in my mouth. After many checks etc it was decided that it was just inflammation of the small blood vessels making them fragile, the same thing was happening in my skin. When things were generally more under control it eased off. However when things get worse again it comes back! It is now never as bad as it was before I had treatment.
