If the pH is correct, then excess chlorine (within reason)in a pool should not be detectable to human senses.
If you can smell chlorine, the pH is not correct, meaning the pool is too acidic or too alkaline.
Too much alkaline will hurt your eyes as it changes the balance (composition) of the of the "tears", making them feel dry and scratchy. Too much acid will sting your eyes, and in extremes burn slightly.
Believe it or not, getting green hair from a swimming pool is due to a lack of chlorine, not excess chlorine.
A pool is usually milky because the system has not been circulating the water enough, IE. the pool equipment has not been operating enough hours per day to filter out the minute suspended particles "floating" in the water.
A fairly common problem with fluctuations in guest numbers and poorly trained pool maintenance staff.
