Have i damaged my eye from looking through a dslr viewfinder with a 300mm lens pointed directly at the sun?

Question by Sondre Blablablabla: Have i damaged my eye from looking through a dslr viewfinder with a 300mm lens pointed directly at the sun?

I took about 10 pictures(i’d say i stared at the sun at about 15 sec. or maybe less in total) of the sun at about 3 o’ clock with a clear blue sky and a very intense sunlight. I used a 300mm zoom lens fully zoomed and pointed it directly at the sun while looking through the viewfinder. I dont know if the aperture i used has any meaning but i used f32(small opening) and Shutter 4000s, have i damaged my eye(retina) and/or the camera? (The images seem a little bit more noisy, but maybe that’s just my imagination.) After the shots i felt the eye i used saw everything in a greenish light for a few minutes. but since then i havent thought about it till i got home from the trip and researched it. if i close one eye, each of them seem just as good, only that the eye i used feels a little “tired” and and a tiny bit blurry at some times(maybe just imagining) what do you guys think?

You probably burned your cornea. Its not such a good idea to stare at the sun, let along through an optic lens of some kind. Galileo made some of the earliest observations on the sun through a telescope and went blind shortly after.
