One of my workers has severe UV reactions too. We installed Sun-tek Ceramic-Carbon Film at 55% on her all black car and she's been loving it. She hasn't had any reactions since we have installed it. She says "Yeah I would recommend the Ceramic-Carbon, it helps with my sun issues and I don't feel the heat from the rays anymore." The Sun-tek one rejects 44-48% of heat and 99% of the UV rays. We have not had any issues with it, I know some have but I guess it's all preference.
