The Production Line of Sight (Infographic)
Blue, brown, or hazel, our eyes are amazing mechanisms. They work much like a very complex production line converting “light” into “sight”. And it all happens faster than the blink of an eye. (Click The Graphic For A Close Up)

[...] But how does this process of “light into sight” translation work? Glasses manufacturer Zenni Optical has put together this innovative graphic that likens the whole process to a production line, where the end product is the image in your [...]
I order from Zenni alot for me and my family. Love their glasses and have enjoyed every pair I ordered so far. Will be ordering again soon..
It would be nicer if it also included and explained some of the other common problems, especially long-sightedness, presbyopia, and especially astigmatism.
What a great suggestion Peter, We’ll be sure to write some follow up posts about those topics in the coming weeks.
we have a post about astigmatism if you wanna read more about that.

Good graphic. A couple of constructive criticisms, though (and yes I’m being picky). In Step 1 it says the cornea focuses light — this could make it easy for some to mistake the cornea for the lens, since we already know that’s what the lens does. Perhaps draw a distinction. Then it says the aqueous humor circulates through the eye, which makes it sound like throughout the entire eye, and so might be confused with the vitreous fluid in Step 2. Finally, in Step 3 it says cones are packed into fovea, but fovea is not defined, as technical terms need to be for those who may not have them readily available in memory. (Sorry, just the persnickety editor in me.) Otherwise, a helpful visual aid. Thanks for providing it.
I like your graphic BUT clicking on it only makes it smaller! Perhaps yo could offer it again as a .pdf file, jpg, or whatever. I would really appreciate being able to print out something letter size. Posey
Hi Posey,
Try double clicking the link, it should expand to a full size graphic.
est se possible d,avoir le cite en francais merci
Zenni glasses are awesome. I won’t buy another pair from a retailer. The quality is suberp and the customer service is incredible too. They really want to please their customers.
I will be ordering glasses again , But the one I once received were too tight in the temple and the ear area . and they are leaving a mark in front of my ear
what is the name of the measurement that corrects this problem ?
Beautiful representation of how th eye works. Great job!
There’s certainly a lot to know about this issue. I like all the points you have made.
