Hello and thanks for your question. How much of a splash was this? A few drops or more of a deluge, that hit the eye?
Depending on whether this was a drop or two that hit his eye versus a significant volume of the chlorine water that splashed his eye, his outcomes can be quite different. If it's just a drop or two, I would expect that he will feel quite uncomfortable with the eye burning, stinging, and perhaps feeling somewhat like there is some sand in it, but in the end he shouldn't be too bad from this. If it was a significant volume of the chlorine water that splashed in the eye, it may cause an altogether worse reaction such as a large-sized corneal abrasion (scratch) which can be quite painful and may take several days to heal. Either way...
Either way, he should have the eye rinsed out for 10-15 minutes at a time, two-three times with water and after that he should use artificial tears 4-5x/day in that eye, cool compresses liberally, and/or tylenol or advil as needed for pain. However, if he is in significant pain and/or the vision is significantly altered he should see his ophthalmologist. Does that make sense?
The burning can last for several days, but usually the worst is the first 24-48 hrs.
