You know Jesus wasn't his really name. Jesus is a Greek translation of Yeshua which translates from Hebrew to Joshua and its not Christ because it wasn't Joseph and Mary Christ.

The guy in the video wears a very bad model of sunglasses: with no protection to the sides. This way, it will open your pupils wider, thus letting even more UV light enter your eyes (from the sides) -- counter-productive for eye health. Talk about knowing how stuff works...

[masterq17]

@ccd101 the pupils will constrict when light enters from the side and the person would still squint thus reducing the light rays and UV radiation as if he weren't wearing sunglasses. but having the sun glasses will still protect him from the majority of them. But if someone were to look through the front of the tinted lens and the lens doesn't block UV then that would expose the deeper structures of their eye to UV radiation.

@masterq17

"the pupils will constrict when light enters from the side"

No, the pupils are wide because you look straight ahead into the dark (thru the glasses in front of the eyes). Yet the UV radiation enters from the sides. Quoting from an EZine article on this: "But even with lenses that absorb 100 percent of UV radiation, light still can get to the eye from the tops or sides of the sunglasses, which is why side shields are an excellent idea for anyone ..."

[masterq17]

@ccd101 yes it is true that the sunglasses wont block the uv from the side, but the pupils react to light stimulus so it will still contrict even thought the focus is forward. ya this guy doesn't really know that much. Polarized lenses block light in the horizontal merdian, not just when its reflected off a flat surface like he said. The way he explains it seems like the focus is more about light than UV.

[skyfire1129]

Maaybe it's just me. But did jesus tell everyone they would burn in hell if you didn't love him? I mean what if I lived on the other side of earth when jesus died. They didn't have e-mail back then!

[mcgge7]

@skyfire1129 it says if you don't hear about him on earth you won't go to hell

[LegoBloxxer]

they use sunglasses mosty in the winter so you DONT GO SNOW BLIND

[mephil8800]

you're a typical religious Nutt. Do your eyes look like a dogs eyes ? probably not because they're different. Do Seagulls wear sunscreen to prevent skin cancer ? do sharks use a toothbrush to prevent their teeth rotting ? humans are vulnerable to things animals aren't. Sunglasses help protect our eyes against the sun...
