I have sungazed for 8 years, in early morning, and my eyesight hasn't been damaged. Now I don't go staring at the sun during the day time, but I have found that when driving in late afternoon when the sun is usually blinding everyone and most people are wearing sunglasses, I have no problem with the sun being in my eyes, it doesn't hurt and I can see fine without sunglasses or the sun visor in place. Its pretty cool. Still, I wouldn't advise people to go looking directly at the sun during the middaytime hours.
