eye capillary ruptured (subconjunctival hemorrhage)

Woke up several days ago and noticed my eye was solid red on the inside half. Looks frightening to others - lol. The day prior i did one AFAP 50 fr from a block, and a half dozen AFAP 15m UWDK's, diving from the side of the pool. Used a new socket-type of goggles that may have been a little too tight. Assuming the inside corner of the lens may have brushed the eye. But I also worked out heavy with weights that day (read that straining can cause this), so I'm not exactly certain which is the cause. Has anyone else experienced similar superficial eye trauma from swimming?
