What is Glaucoma?

Glaucoma is a  condition of high pressure within the eyeball causing gradual loss of sight. According to the World Health Organization, Glaucoma is considered as the second leading cause of blindness (behind cataracts)in the global level . In simple words, Glaucoma is a complicated eye disease caused by high eye pressure, and if left untreated causes permanent vision loss or blindness.It is called the “Sneak Thief of Sight” or “Silent Thief of Sight”. How the Eye works? Eyes The eye works very much like an old-style camera. In the camera, the light comes in through the shutter, is focused by the lens, falls onto the film and them we take it to be processed. In the eye, light comes in through the cornea and pupil. It is focused by the lens, falling onto the film in the eye (the retina) and then goes, via the optic nerve (the nerve of sight), to the brain (the processor) for developing. The shape of the eye is achieved through the circulation of a clear fluid (aqueous

Improve Vision - Eye News

Video games helps to improve vision. Playing action video games can boost an aspect of adult vision previously thought to be fixed, a US study shows. Researchers found playing the games improved the ability to notice even very small changes in shades of grey against a uniform background. "Contrast sensitivity" is important in situations such as driving at night, or in conditions of poor visibility. The Nature Neuroscience study raises the possibility of using a video game training regime to improve vision. Contrast sensitivity is often one of the first aspects of vision to be affected by ageing.  It can also be affected by conditions such as amblyopia, known as "lazy eye". Improving contrast sensitivity usually requires physical changes in eye optics, through eye surgery, glasses or contact lenses. A team from the University of Rochester studied expert video game players playing games involving aiming and shooting at virtual targets. They found

Why Children are wearing glasses in young age? - Eye News

Up to 90% of school leavers in major Asian cities are suffering from myopia(short-sightedness)and scientists are blaming their academic lifestyles. Natural light exposure is just one potential factor in a child's eyesight. The time children spend outdoors could be linked to a reduced risk of being short-sighted, research suggests.   Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light. They also found a strong link between short-sightedness and close reading. The work of Professor Ian Morgan, from the  Australian National University in Canberra , and colleagues, suggest the condition - also known as myopia - is due more to environmental than genetic factors. The scientists told  The Lancet medical journal  that up to one in five of these students could experience severe visual impairment and even blindness. According to the research, the problem is being caused by a
