The reason myopia occurs is due to the irregular shape of the eyeball. When the eyeball is not shaped correctly, the cornea does not manage to focus properly and the light rays that are reflected in the eyes divert irregularly. This causes difficulty in focusing on objects. While some people believe that myopia is a hereditary condition, the truth is that it is also commonly seen a number of patients who have ho history of myopia in the family. In most cases, myopia develops at a young age and can be identified as a child. The condition might or might not continue to worsen as a child grows. It stabilizes once an adult in most cases, but there are reports of myopia worsening with age too.
While it is common in people with no history of the condition too, parents who suffer from myopia need to take extra care to ensure their child does not suffer from the condition. In case your child is identified with the condition, it is crucial to begin myopia treatment as soon as possible to limit the damage to the eye.
Symptoms And Signs
One of the first signs of Myopia will be difficulty in seeing distant objects or reading road signs clearly. However, yours eyes will be perfect when it comes to using a computer or reading. All tasks that need to be done really close will be easy to do. The other signs of Myopia include straining the eyes, squinting and severe headaches. You will start feeling tired when playing any kind of sports or while driving. This could be due to nearsightedness. If these signs persist even after wearing contact lenses or glasses, you should visit an optometrist or an ophthalmologist immediately.
Myopia can be treated in many ways. The various forms of Myopia treatment include using contact lenses, using glasses or in some cases opting for refractive surgery. Every patient has a different degree of Myopia. Depending on this degree, you may have to wear contact lenses or glasses all the time or only if you need a clear vision like watching a movie or driving. If you are nearsighted, the very first sphere on your contact lens or your glasses prescription will have a (-) sign before it. The number following the minus sign denotes the power in the eye. The higher the number is, the severity of nearsightedness gets higher. Refractive surgery can also eliminate or reduce the need for contact lens or glasses. These surgeries are usually performed with an excimer laser.
