Short-sightedness and long-sightedness are common refractive errors. In the former, image id formed in front while in the latter, the image is formed beyond the retina. Different correcting options are available for both short-sightedness and log-sightedness. <\/p>\n
A healthy vision is important to see clearly. Clear vision improves the quality of life and helps to enjoy life to its fullest. Viewing the objects around us is a complex process. All the parts of the eyes function synchronously to provide a clear image of the focussed object. The problem in any of the ocular parts may result in poor vision. Light falls on the cornea and is diverted to fall on the retina. The light then passes through the pupil, which is the entrance gate into the eyes. The light, after passing through the lens falls on the retina. The cells of the retina get activated and transfer the information to the brain via the optic nerve. The brain processes the information and the process of viewing gets accomplished.<\/p> \n
Any problem in the focusing of light on retina i.e. falling of light in front of the retina or beyond the retina results in blurred vision. The disorders are combined to denote refractive errors. Various treatment options are available to manage the refractive error.<\/p>\n
Short-sightedness is also termed as myopia. It is a type of refractive error. In this condition, the person is not able to see the distant objects clearly while there is no problem in viewing near objects. In the healthy vision, the image is formed on the retina, while in myopia, the image is formed in front of the retina. This results in blurred vision for the objects which are far away. Short-sightedness is one of the most common refractive errors throughout the world.<\/p>\n
Long-sightedness is also termed as hypermetropia. Unlike myopia, long-sightedness is characterized by the inability of a person to see the near objects. It is to be noted that our eyes are accommodated and focussed to see the far objects. While we are young, the focus on far objects is compensated by the muscles of our eyes. However, as we age, this compensation gets reduces and we face problems in focusing on near objects. Thus, by mid-40s, people require reading glasses. In long-sightedness, the image of the object is formed beyond the retina.<\/p>\n
Both short-sightedness and log-sightedness are refractive errors. However, both are different. In short-sightedness, the person is not able to see distant objects while in long-sightedness, the person is not able to see near objects. Image is formed in front of eyes in short-sightedness while it is formed beyond the retina in long-sightedness. The glasses of negative power are required in short-sightedness while positive power glasses are required in long-sightedness.<\/p>
Following are some of the treatment options for refractive errors:<\/p>\n
Glasses:<\/strong> Glasses are one of the most common options for people with refractive errors. However, because of the problem of handling glasses, many people opt to get rid of glasses.<\/p> \n Contact lens:<\/strong> Those people who do not want to wear glasses, contact lens is another option. However, care is required while wearing the lens as these have the potential to cause infection. <\/p> \n LASIK surgery:<\/strong> In LASIK surgery, the refractive error is managed by reshaping the cornea with the help of laser.<\/p>\n Intraocular lens:<\/strong> The intraocular lens is fitted in those people who do not have the option for LASIK surgery.<\/p> \n Refractive lens exchange:<\/strong> During this process, the natural lens is replaced with a synthetic lens. The multifocal lens may be used that can focus both on the far and near objects. <\/p>\n All surgical processes are safe and effective in correcting refractive errors.<\/p>\n","protected":false},"excerpt":{"rendered":" Introduction Short-sightedness and long-sightedness are common refractive errors.
