yes its definately the water splshes that cause irritation it happens every 3 weeks when i do a couple of houses that dont have much room to stand back im more or less directly under the window ive tried a few types saftey glasses but these havent helped much as splashes come down the backs of the frames goggles are a option but they do tend to mist up the irritation last for around 4 to 5 days if the water is good 4 car battries are we sure it wont damage our eyes after all pure water is aggresive water
