In the last 8 months i lost sight in 1 eye, later diagnosed with a pituitary brain tumor.. it was removed by inevasive surgery thru my nose and was benign..im recooperating and returned to work.. BUT, as i read on.. a chemical named butoxyethanol causes the exact situations.. i never put the 2 together, but since i was a little boy i was involved in the printing and automotive re-finishing trades.. my dad had this always as i grew up around home, later i, myself was in both trades till the present im still exposed to this.. more in the 70-80's.. but ..BEWARE a simple thing like painting cars and using printing inks and solvents, platemaking has been proven to cause these tumors.. have an MRI to check before you loose sight.. it was instantly for me, never wore glasses.. but also had red blood cell problems many yeaars back i recall.. never put all together till now.. take care and like to hear and help someone else.
