Farsightedness, also known as hyperopia or hyperopia, is a common refractive eye defect. It is classified as a sight defect related to the abnormal refraction of light in the eye. It is also defined as blurred vision of objects that are close by when you can perfectly see objects that are far away. So for people with farsightedness reading a book or watching TV can be a problem. However, objects that will be far away will be clearly seen. In this defect, the range of vision depends on the size of the defect.
Do correction of farsightednessand it is best to use corrective glasses or contact lenses. They will properly focus the light beam in the eye. As a last resort, surgical methods will be the salvation to eliminate a large defect.
Foresight it is most likely a hereditary disease. With this defect, incoming light does not focus properly in the retina. This may be because the knob will be shorter than it should be in its standard size. The image will then focus at a short distance behind the retina and focus problems will emerge. Therefore, a book held closely in our hands will be blurred for us, and objects that will be in the distance will be perfectly visible.
Foresight very often diagnosed in children. In its early stages, it seems to be related to farsightedness physiological, which is related to the continuous development and shaping of the eye, and more specifically the eyeball and the entire optical system. It should disappear over time, but sometimes it stays longer and turns into a serious defect. In adults, however foresight it may be caused by diabetes, which damages blood vessels.
The beginnings farsightedness are almost imperceptible. They can appear slightly blurred in seeing objects close to you, while perfectly visible objects in the distance. Over time, as the disease progresses, the sharpness of those close-up objects may deteriorate and they will become more blurry. Images seen far away will still be in sharp focus. The symptoms are more intense in different age groups, and with age the ability of the eye to accommodate decreases, i.e. the ability of the eye to adapt to the objects viewed at different distances in front of us.
Division of farsightedness is the clinical picture and its stage of advancement. As for the first degree – clinical – the visual defect is simple – it occurs without any cause, pathological – it may occur as a result of an injury, disease or bad development, and functional – resulting from the impairment of the eye’s ability to adjust itself to visible images. The stages of advancement are: low farsightedness – with values up to +2,0 diopters, moderate – from +2,0 to +5,0 diopters, and high – exceeding +5,0 diopters.
Unfortunately farsightedness it cannot be self-healed, but can be easily corrected.
