I did get to see him, with three pairs of cheap sunglasses that they sell on the streets for a while.

I have no idea if I will now have permanent vision damage.

Most sunglasses only filter out visible light (cheaper to manufacture that way), and are almost perfectly clear to both UV and infrared frequencies. Because your pupils expand and contract based on the visible light reaching them, wearing sunglasses actually makes your eyes more vulnerable to damage from sungazing, compared to when your pupils would be tightly contracted staring naked. However, the extent of eye damage also depends on your personal eye chemistry, based on retinaldehyde and antioxidants and so forth, so the degree of eye injury can vary widely from the same exposure. Another factor is how high in the sky the sun was; if the sun is less than 30* above the horizon, the UV that actually reaches the ground decreases exponentially (decreasing by 50% each successive 5* lower or so), which is why sunsets or sunrises don't usually hurt your eyes at all.

it was literally noon, although it was cloudy, so I could see the sun perfectly through the clouds.

I haven't really noticed any change so I'm not that alarmed.
