Myopia is the medical term that refers to nearsightedness. Individuals who are nearsighted or “myopic” have fuzzy or unclear distance vision, but can see well at close range without using any glasses or contact lens correction. Most importantly, the vast majority of nearsighted people with healthy eyes can almost always be corrected by PRK or LASIK Treatment in Dubai.
Myopia is thought to be a be result from a number of hereditary and environmental factors. A significant percentage of myopia is inherited from those along the family line, because the shape and length of the eye are primarily genetically determined and together establish the focal point of the eye. Myopia can start in early childhood and develop significantly later on in life. Nearsightedness is also quite common and usually affects up to 20 to 40% of the population, explains the eye clinic in Dubai.
The fuzziness caused by this condition is due to the way in which the light travels through the front of the eye and how this image is later focused on the retina at the back of the eye. When an individual’s visual system is functioning properly, these images are focused clearly from the front eye surface all the way to the back of the eye. Nearsighted people have a condition called a “refractive error” which means that the image is not focused properly on the retina. This refractive error may be caused by the cornea or the front surface of the eye being too steep or too flat, or simply by the overall shape of the eyeball being unusually long. In myopia, the focal point is not directly on the retina where it should be, but rather is focused in front of the retina. From the patient’s point of view, this blurry retinal image is because it reaches the brain where the actual “seeing” occurs.
Individuals with myopia often experience minor inconveniences such as needing to squint while trying to read the papers, road signs or occasional eyestrain. In some individuals, nearsightedness is known to case, mild, moderate, or even severe headaches. Since myopia tends to develop at an early age, it is important to look for signs that a child may be nearsighted. If your child can’t see the blackboard or smartboard and needs to sit very close to the television, or squints and blinks excessively, these may be early signs of myopia, warns the eye surgeon in Dubai.
Myopia tends to get worse during adolescence because of the natural growth of the eyeball along with the rest of the body and hormonal changes. Eyeglasses or contacts may be used to rectify this condition and return to an individual’s normal daily activity. Wearing eyeglasses may need to continue till the patient is 18 years, when the growth of the eyeball is complete. Thereafter, laser vision correction treatment such as PRK and LASIK Dubai can be considered as the best alternative to eyeglasses or contacts, as this procedure can provide permanent vision correction on the long run.
Summary: It is a good idea for most patients to schedule an eye exam with the eye clinic in Dubai if their eyesight without glasses or contacts is blurry enough to affect their ability to perform basic tasks or interferes with everyday activities.
