As a person with astigmatism, night driving is so painful in KL

I absolutely despise high beamers and cars with altered LED lights. I literally got a black spot in my vision thanks to a guy high beaming me because a kiosk reject my TNG a few times into a parking lot. I get those people if you wanna go fast on right lane but if theres traffic what tf you high beaming for. And the only solution i have is to pay thousands for specialised glasses to not get flashbanged everytime. Seriously i want to know their reasoning for flashing every damn car.
