Answer: Myopia, also called nearsightedness or shortsightedness, is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed.Those with myopia see nearby objects clearly but distant objects appear blurred. With myopia, the eyeball is too long, or the cornea is too steep, so images are focused in the vitreous inside the eye rather than on the retina at the back of the eye. The opposite defect of myopia is hyperopia or "farsightedness" or "long-sightedness" - this is where the cornea is too flat or the eye is too short.
Answer: Approximately one out of 10,000 people in the United States develop retinal detachments each year. People who are at highest risk are those with extreme nearsightedness (hypermyopia), a family history of retinal detachment, or thinning of the retina (lattice degeneration) or other degenerative retinal conditions. Such people should have regular retinal examinations and should be alert for symptoms.http://www.mdsupport.org/library/detach.html
Answer: The doctor has the patient view images through a variety of lenses to obtain the best correction. The doctor also examines the inside of the eye and the retina. An instrument called a slit lamp is used to examine the cornea and lens.
Answer: By minimizing the amount of accommodation (near-focusing) your eyeshave to perform. This does not necessarily mean you have to avoidclose-up activities like reading and using a computer. It ispossible to avoid accommodation while dong this with the use ofreading glasses. This practice is known as plus-lens therapy.
The reading glasses allow you to ensure your eyes rarely have tofocus any closer than the furthest point at which you can seethings clearly. This is achieved by bringing your focal range incloser, effectively making you more myopic. For those who spend alot of time looking at a computer screen about half a metre away,giving yourself 2 effective diopters of myopia would be ideal -your focal limit is approx. 1 metre divided by the number ofuncorrected negative diopters.
The strength of reading glasses that would be appropriate woulddepend on what your current prescription is. Using reading glasseswould only really be feasible for those with a prescription nostronger than about -1.50 D. Simply add +2 to your prescription tofind the required strength, e.g. say you were -0.75... -0.75 + 2.00= +1.25. Reading glasses can be bought fairly inexpensively onEbay.
Those who have close to 2 diopters of myopia to begin with couldbenefit from simply removing their distance glasses when on thecomputer or reading. Those with higher prescriptions, i.e strongerthan -3.00 D, may like to consider getting a reduced-strength pairof glasses specifically for reading/computer use; one that is 2diopters less than their full prescription. There are some low-coston-line glasses suppliers that can make this easier on your wallet,e.g. zennioptical and goggles4u.
What is cultural myopia?
Cultural myopia occurs when information entering into the colonized mind is focused solely through a limited worldview, and anything existing outside of that limited worldview cannot be seen with clarity.
Answer: Cultural myopia occurs when information entering into the colonized mind is focused solely through a limited worldview, and anything existing outside of that limited worldview cannot be seen with clarity.
Answer: With cultural convergence, cultures are coming together. Withcultural divergence cultures are kept separate. Celebrating CincoDe Mayo in the United States is an example of cultural convergence.The Day of the Dead Celebration in Mexico is an example of culturaldivergence.
Answer: Evolution is the gradual change over time, where new parts may added and old ones either adapted, altered or removed. Diffusion is the slow "creep" from one area to all of the surrounding ones, where parts of one culture are absorbed by others nearby.
Answer: Cross culteral refers to "crossing" over cultural lines to have a relationship with someone of a different culture. Intercultural refers to having a relationship with someone of your own culture.
Answer: In the myopic eye, the focusing power of the cornea (the major refracting structure of the eye) and the lens is too great with respect to the length of the eyeball. Light rays are bent too much
Answer: Myopia is a refractive defect of the eye in which light produces image focus in front of the retina when the sight adjustment is off balance. People with myopia see nearby objects perfectly, if not almost, clearly. Distant objects are blurred since the eyeball is too long or the cornea is too steep. Basically it means that one is nearsighted. a condition of the eye in which parallel raysare focused in front of the retina, objects being seendistinctly only when near to the eye; nearsightedness
Answer: Vision Improvement /Myopia Correction with Homeopathty
Another name of Myopia is near-sightedeness.In this disorder Closeobjects are seen clearly, while distant objects are seen blurred.Humans use corrective lenses or corrective surgery to improve theirvision. Myopia can be slowed down or cured with help of Homeopathymedicines also.I have been interested in alternative medicineapproach like Homeopathy ,Acupressure ,Yoga ,Ayurveda etc to cureMyopia or improve vision.For this purpose i made my blog for thebenefit of people.The blog address is eyecarehomeopathy.blogspot.com
