Each eye can make a 576-megapixel image 1000 times per second. With the use of https://toolstud.io/photo/megapixel.php, I found out each eye makes 1.01TB of lossless JPEG images per second, if we think it's a camera. So if you have two 100% functioning eyes, you generate potentially 2.02 terrabytes each second. Through a day cycle, that is 174.528 petabytes. Through a full year, that is 63746.352 petabytes. (thinking one year is 365.25 days)

Worldwide, including blind people and people with low vision

With the source of https://www.who.int/blindness/GLOBALDATAFINALforweb.pdf I found out 39.365 million people are blind. If we think "Low Vision" means having only one eye, we have 256.024 million people who only have one eye. And we will ignore "Visually Impaired" to balance it out a bit.

So in total, with this source, and the fact that there is 7.53 billion people on earth, we have 14,725,246,000 eyes on earth. Using the tool mentioned in the beginning of this, and thinking all eyes makes 1.01TB of images per second, all humans on earth makes 12.7226125 zettabytes per second.

That is 12,722,612.5 petabytes every second. Through a day cycle, that is 1,099,233,720,000 petabytes. Through a full year, that is 401,495,116,000,000 petabytes. (thinking one year is 365.25 days)

Calculating sleep

If we average it out to that a person sleeps 8 hours a day, one person processes... Through a day cycle, that is 116.352 petabytes. Through a full year, that is 42497.568 petabytes. (thinking one year is 365.25 days)

And with all humans, Through a day cycle, that is 732,822,480,000 petabytes. Through a full year, that is 267,663,411,000,000 petabytes. (thinking one year is 365.25 days)

Compression

With the source of https://homepages.cae.wisc.edu/~ece533/project/f06/aguilera_rpt.pdf I found out a lossless JPEG can be compressed down to half the size, without losing quality. If we press it down to 50% quality, we get a ratio of 1536 : 99, so 1536 bytes is now rather 99 bytes. If we press it down to 10% quality, we get a ratio of 7680 : 163. If we press it down to 1% quality, we get a ratio of 2560 : 21. These numbers may not be, and probably aren't even close to being accurate.

Final results

Everything in this table is measured in petabytes. One second per person is not included, since it's <0.001 in all fields.
