There are many methods to this pretty simple task.

I don't think you need to adjust the actual veins of the eye, I would suggest just creating another layer above your eye image, set it to about 10-20% opacity and use the paintbrush tool with about 60% hardness and colour in the whites of the eye red.

Adjust the opacity of the layer if you're not happy with the result.

STEP-BY-STEP:

1. Create new layer:




2. Choose your brush:




3. Make your brush red:




4. change the hardness and size of your brush:




5. colour over the white of the eye on the new layer:




Then just adjust the layer opacity to get your desired red level.
