It depends on the situation. I've heard that the brain processes images at about 30 fps under normal conditions. But if you're scared the brain can process images at closer to 60 fps. I've even heard the eye can see up to 300 fps, but I'm not too sure about that.
The shutter speed of the human eye is much faster than that of a camera. The eye can perceive and process images in a fraction of a second, while a camera's shutter speed is measured in milliseconds.
An image typically persists on the retina of the human eye for about 1/20th of a second. This phenomenon is known as iconic memory or persistence of vision. It allows us to perceive a continuous image even though the retina receives discrete snapshots of visual information.
The best way to fix broken eye glass frames, aside from tape or super glue at home, would be to take them to an eye care specialist for repair. Some places, whether one uses their services normally or not, will do simple repairs for free, while some others may charge a small to moderate fee.
The human eye can refocus on objects at different distances within milliseconds, typically ranging from 300 to 500 milliseconds. This rapid adjustment is made possible by the eye's ability to change the shape of the lens to bring objects into focus.
Cones perceive color in the human eye.
30 frames per second is the minimum rate that it takes to fool the human eye into believing that a series of still pictures are moving.
Typically, a minimum of 24 frames per second is needed for still images to appear as smooth motion to the human eye. This is the standard frame rate for movies and many animations.
A human eye can blink in about 100 to 400 milliseconds, meaning it can make a blink in roughly 0.1 to 0.4 seconds. However, in terms of processing visual information, the human brain processes images at a rate of around 60 frames per second (fps), which is the equivalent of perceiving about 60 distinct visual images in one second.
The eye moves 50 times every second. - This is a Snapple Real Fact #172
Your eye doesn't see in frames per second (fps) - and it's hard to determine how many fps the eye would be because of the way people construct video and use frame blurring. The average cinema film is done in 24 frames per second. Because the eye doesn't have a shutter means its constantly viewing (until you blink). http://www.100fps.com/how_many_frames_can_humans_see.htm
Frames Per Second - It refers to the speed at which the image is refreshed. The higher the FPS, the more smoother the video/game is; however, the human eye can't tell the difference over high FPS rates
The human eye is estimated to have a resolution of 576 megapixels.
None. Actually the eye is held in place with the help of the skull.

There are many good places to get eye glasses from including, Frames Direct, Lens Crafters and Zenni Optical, all of which provide excellent eye care.
One on each eye...i think
To avoid confusion, keep in mind that eyes are not able to see, meaning that the number of frames an eye can capture per second usually differes from the number of frames the brain can process. The human brain processes about 20 frames per second, but can go as high as 60 when in panic. This is purely made for survival purposes, and can only be achieved by reducing other important brain activity (which you would need for rational thinking, emotions or social interaction, for example). This also explains why, when you are in panic, you perceive everything as being in a sort of slow motion, compared to how fast you would normally perceive things. This is so that your brain can know and decide where to go next in a dangerous situation (as falling to ground, or being chased by a wild animal). However, the human eye is able to capture much more frames per second, even higher than 200 fps in some cases. This varies a lot from person to person, and it does not change the fact that your brain processes 20 fps. Since the human eye perceives information continuously, at a rate much higher than the brain can process, you would not be able to see at 200 fps. Under ideal conditions you would even be capable of processing the afterimage of a single frame that had been shown for 5 milliseconds (wich corresponds to 200 fps) or less.
