Red Eyes

Woke up this morning and the left side of my left eye is red(been red all day), I could have possibly popped a blood vessel in my eye. The previous day I was benching, and I notice that when I start to fatigue, there is a lot of pressure in my head while I am holding in my breath during the rep. Does this mean I am performing the Valsalva maneuver incorrectly because I am allowing the pressure in my head? Could I have possible popped a blood vessel while I was benching? The pressure in the head only occurs during the bench when fatigued at the last couple of reps.

Is red eyes a normal side effect of performing the Valsalva during a heavy set that is around RPE 8+?

This is common, yes.

I can’t tell you for sure whether or not you are performing the valsalva correctly. Most of the pressure should be generated in the chest/abdomen, but of course there will be some of this transmitted to the head/face.
