Perception requires imagination because the data people encounter in their lives are never complete and always equivocal. For example, most people consider that the greatest evidence of an event one can obtain is to see it with their own eyes, and in a court of law little is held in more esteem than eyewitness testimony. Yet if you asked to display for a court a video of the same quality as the unprocessed data catptured on the retina of a human eye, the judge might wonder what you were tryig to put over. For one thing, the view will have a blind spot where the optic nerve attaches to the retina. Moreover, the only part of our field of vision with good resolution is a narrow area of about 1 degree of visual angle around the retina’s center, an area the width of our thumb as it looks when held at arm’s length. Outside that region, resolution drops off sharply. To compensate, we constantly move our eyes to bring the sharper region to bear on different portions of the scene we wish to observe. And so the pattern of raw data sent to the brain is a shaky, badly pixilated picture with a hole in it. Fortunately the brain processes the data, combining input from both eyes, filling in gaps on the assumption that the visual properties of neighboring locations are similar and interpolating. The result - at least until age, injury, disease, or an excess of mai tais takes its toll - is a happy human being suffering from the compelling illusion that his or her vision is sharp and clear. We also use our imagination and take shortcuts to fill gaps in patterns of nonvisual data. As with visual input, we draw conclusions and make judgments based on uncertain and incomplete information, and we conclude, when we are done analyzing the patterns, that out “picture” is clear and accurate. But is it? ↗

One reason I'm such a wayward prognosticator of rightwing trends is that I'm incapable of blacking out enough neural sectors to see the world through reptilian-brained eyes, a prerequisite for any true channeling of the mean resentments and implanted fears that drive hardcore conservatives. ↗
Cataract Treatment Advanced by Laser Eye Surgery It is estimated that half of individuals aged 65 and above will grow a cataract at some period in their life. A cataract is an eye condition that may be hazardous to your eyesight. In a healthy eye, there's a clear lens which enables you to focus. For those who have a cataract, the lens slowly deteriorates over a long period of time. Your vision can be blurry as the cataract develops, until the whole-of the lens is muddy. Your sight will slowly get worse, becoming blurry or misty, which makes it tough to see clearly. Cataracts can occur at any age but generally develop as you get older. Cataract surgery involves removing the cataract by emulsifying the lens by sonography and replacing it with a small plastic lens. This artificial lens is then stabilised within your natural lens that was held by the same lens capsule. The results restore clear vision and generally wholly remove the significance of reading glasses. However, years following the surgery, patients can occasionally experience clouding of their sight again. Vision can become blurred and lots of patients have issues with glare and bright lights. What is truly happening is a thickening of the lens capsule that holds the artificial lens. Medically this is known as Posterior Lens Capsule Opacification. This thickening of the lens capsule occurs in the back, meaning natural lens cells develop across the rear of the lens. These cells are sometimes left behind subsequent cataract surgery, causing problems with the light entering the-eye and hence problems with your vision. Laser Eye getlasereyesurgery.co.uk y Treatment Lasers are beams of power which may be targeted quite correctly. Nowadays the technology will be used increasingly for the purpose of rectifying the vision of patients after cataract operation. The YAG laser is a focused laser with really low energy levels and can be used to cut away a small circle shaped area in the lens capsule which enables light to once again pass through to the rear of the artificial lens. A proportion of the lens capsule is retained in order to keep the lens in place, but removes enough of the cells to let the light to the retina.

The things sane societies loved, it hated. The things sane societies hated, it loved; the things sane societies tried to do, it tried to avoid; the things sane societies tried to avoid, it did with relish. It pursued chaos and hated order, it worshipped ugliness and loathed beauty. If sane people wished to dress as neatly and well as they could, these people were persuaded to dress as hideously and grotesquely as possible; if sane people wanted music to be melodious, these people (whether we are speaking of their "popular" or their "serious" music) were cozened into believing they liked raucous and tuneless noise. If women had been feminine, if home life had been secure, if children had been innocent, if men had been gallant, if art had been beautiful, if love had been romantic, then all these things must be stood on their heads. Of course, life was not always like that. Of course things had often fallen short of their ideals, or even of their minimal norms; but at least most people tried to do things properly and at least the surrounding civilisation encouraged them to try. Never before had the deliberate aim been an inverted parody of all that should be. Everywhere, in every area of life, a single principle reigned: inversion; the worship of chaos; the creed of the madhouse. ↗

I remember a relative of mine who used to pick on me all the time, constantly ridiculing my every move and making me feel inferior. One day she had a pimple on her face and was devastated. I told her "Why would you let a little thing like that bother you in such a way? It's just a pimple!" And she cried and said "You can say that, because you're perfect and even if you have ten pimples on your face, it wouldn't even matter!" And I never forgot how I felt in that moment, that moment taught me some important things! First, I realized that the whole time she was picking on me, she actually was feeling that I was perfect! And secondly, I realized that when people think you're perfect, they try to make you feel bad about yourself! I was so taken aback in those few minutes— I couldn't even say anything! I just looked at her while all my realizations flooded my mind and I decided that just because you think someone is perfect, doesn't give you the ticket to make them feel bad about themselves. ↗
