Sight is a precious gift that we don't realize that we take for granted. Our eyes are windows to the wonders of the world. All we know love and experience and discover ponder and cherish. The workings of the eye are a unique and sustaining system. I'm sure by now the whole world has heard about the dress, it’s the debate that has captivated the Internet. This viral story raises an interesting medical questions about one of our 5 senses, sight. Why do to people perceive the same image in different ways the answer is actually quite simple. This dress is polarizing the Internet into 2 camps and people across social media have been arguing rather this dress is blue with black lace or white with gold lace. My mother and I have gone through this as well I say is white with gold lace and she says it's blue with black lace, why? And the answer is it comes down to the way the human brain is evolved to see color.
So we start by seeing how the eyes work. Light comes into your eyes through the front lens and then it hits the retina in the back once it's on the back of your retina the retina then pushes it through the optic nerve and sends the signal for example the green tree to your brain. But there is a catch in order to figure out the real color of that tree or that dress your brain had to a little math it had to subtract out the color of the light luminating the scene. And so what happens is this when you're looking at that tree or that dress some people's brains are choosing to subtract out the blue so they see the dress as white in gold while other people choose to subtract out the gold so they see the blue dress. But that's how we are made and who's to say who's right and wrong and that's how people perceive the same image in different ways.

Light enters to the cornea to project into the retina, whose impulses converges onto the optic nerve and then to the retina to be transformed into imagery in viewed with meaning. Continual adjustments to the pupil in lens regulate the entry and focusing of lights. In today’s world is constantly challenged by things like less sleep dust glare from the computer contact lenses air conditioning heat and pollution. That eye is also challenged to protect itself and adjust to changing conditions. Every blink help are eyes natural defense system. That eye is nearly spherical in shape with a slight bulge in the front. The tear film retains moisture and maintains visual acuity. Tears contain natural potent disinfectants to keep bacteria at bay. The tear system also washes away impurities to maintain eye health. The human eye in my book is the most valuable and sensitive organ and it is a natural optical instruments.
