How does the eye work?

Like a camera. It would take too much spce to go piece by piece but it's workings are very similar to that of a camera.
Eye. The eye functions like a fancy camera. Light enters the eye through the clear surface called the cornea. It then travels through the crystalline lens, where it is focused to a point on the retina, which acts like film in the camera. The retina converts the light signal into electric impulses, which travel to the brain, where they are interpreted as pictures.

How does hand-eye coordination work?

Coordination of the . eyes & hands requires intact circuits in the brain to process visual & proproceptive sensory input & normal ability to produce movement of eyes, hands arms & upper trunk. Proprioception =the brain's ability to process stimuli to maintain equilibrium & position & to produce normal fine- motor motions. Disruption at any site along the complex circuits impairs fine-motor functions. Read more...

I am curious if contacts build protein, how does lasik eye surgery work?

Reshaping the cornea. Lasik eye surgery is using excimer laser to reshape the corneal curvature of the eye to achieve the desire focusing power. A corneal flap is first made and lifted from the eye. Then based on the pre-operative calculation by a computer program, a pre-determined amount of the corneal tissue (the stroma) is removed by the laser beam. The flap is then placed back down on the eye. Read more...
The 2 are not relate. Contacts do not build protein. Perhaps you meant that protein deposits can build up on contacts and decrease their comfort and safety. Lasik surgery is unrelated to contacts and works by reshaping the cornea of your eye to correct your prescription. Read more...

How does an enucleation of the eye work?

Eye removed. In an enucleation, the eyeball is separated from the eye muscles, which are secured with sutures. The optic nerve is then cut and bleeding is stopped. Next, a synthetic implant is placed in the eye socket to take up the volume of the removed eye. The muscles are then attached to the front of the implant with the preplaced sutures. The conjunctiva is sutured closed over the implant. Read more...

How exactly does eye correcting surgery work?

By reshaping . Laser vision correction (such as lasik or prk) utilizes a cold laser (excimer laser) to permanently reshape your cornea (the front part of the eye, where a contact lens rests on) corrrecting your nearsightedness, farsightedness and/or astigmatism. Think of it as permanently "engraving" your contact lens or glasses prescription into your eye. Read more...
Various ways. If not a candidate for lasik/prk, there are others to correct refractive errors such as phakic intraocular lens, clear lens extraction, intracorneal rings, etc. The basic premise is to change the corneal or lens power to focus it directly on the retina instead of in front or behind.

How well does laser eye surgery work?

There are multiple. different lasers and dozens of procedures that are performed using these lasers. How it works really depends on which procedure you are interested in knowing about. LASIK and PRK change the shape of your cornea to allow the eye to focus the light better. Sometimes the cornea is too strong or too weak, and the laser helps us fix that. Hope that helps. .
