Do farther objects or distance appear blurred to you? If so, it is highly likely that you are suffering from nearsightedness, or myopia. This condition is potent enough to affect the quality of your life due to blurry vision. Eye specialists suggest that it occurs if your eyeball is longer than the normal size or the cornea is curvier than it should be. Myopia affects children and adults alike. According to a recent survey, 30% of people develop myopia every year.

There is no study available to describe which factors contribute to the debilitating vision condition. However, it is believed that people either inherit myopia or have a tendency to develop it. There is the likelihood of encountering nearsightedness if you have the family history of this eye disorder. Eye experts revealed that, in most cases, your habits contribute to vision deterioration significantly. For instance, reading or staring at the screen for hours.

Sometimes myopia occurs in childhood and continues to grow until the twenties. In adults, chronic diseases such as diabetes are associated with nearsightedness apart from visual stress. It seems impossible to impede the occurrence of myopia. However, you can control that problem by taking note of following health problems and environmental factors such as:

  • Fluctuation of sugar levels in the bloodstream of people with diabetes indicates myopia. You can visit your eye doctor for further assistance.
  • Most people experience blurry vision during the night This night myopia begins when your eyes cannot focus on an object due to low lighting. Also, sometimes in dark space or room, large pupil size hinders light rays to enter in your eyes. So, try to increase lighting and visit your eye doctor immediately.
  • Visual stress or people whose lifestyle involves near-vision work may develop pseudo or false myopia. Excessive focusing can lead to this condition, as it places pressure on your eyes. After hours of near-work, your eyes take time to refocus on the objects or distance. However, this condition gets back to normal after resting your eyes. It is worth noting that constant visual stress is threatening and leads to blurred vision disorder permanently.

You will be delighted to find that there are options available to clear out your blurry vision to some extent. Whether it has affected a child or an adult an extensive eye examination can determine the type of treatment one may need. Your eye specialist might suggest wearing eyeglasses while working, driving, or reading and contact lenses depending on your condition.

There are surgeries and laser treatment like corneal refractive therapy (CRT), laser in situ keratomileuses (LASIK, photorefractive keratectomy (PRK) available that your eye doctor may suggest after examining your condition. These laser treatments can help prevent loss of vision for people with extreme nearsightedness.
