Myopia and Hypermetropia : Long and short sightedness

Many people have perfect eyesight. That means they don’t need any artificial enhancements to see clearly. Others have conditions that require assistance with their eyesight. Myopia and hypermetropia are contrasting but common eye conditions that affect millions; almost 30 percent of the Americans have Myopia and hypermetropia, for example.

The inconvenience

These two conditions, though not painful, can disrupt normal lives. Aside from limiting literacy, myopia and hypermetropia can make life awkward. These conditions may compel you to wear glasses or contact lenses, which can be quite uncomfortable, even to those who are used to wearing them. Reading glasses do not always fit when they should; you would have to adjust them to keep them in place every now and then. Contact lenses, on the other hand, have to be placed right on the sensitive surface of your eye. Then, you have to take them out and clean them before you go to sleep.

If you have perfect eyesight, it means that you can clearly see things that are close and far away without straining or the need for visual aid. Myopia and hypermetropia simply mean shortsightedness and long-sightedness, respectively.


Myopic or shortsighted people can see things that are close very well, but they cannot see things at a distance. It can affect your ability to read from a book or electronic device, such as a tablet or laptop. Myopia can be corrected with spectacles or contact lenses with a negative power, which brings light into focus. The lens should have a minus power (e.g. -2.00) to reduce your eye’s strength in relation to length.

An increased prescription of lens power does not mean that your eyesight has worsened. It only shows that the shape of your eye has changed. However, the quality of your eyesight remains the same. If you cannot see clearly even after wearing glasses or contact lenses, then you should be worried.

Although it does not usually mean that your eyes are getting worse, it shows that your shortsighted eyes have become longer. This is normal as you age. Your doctor will help you by gradually increasing the strength of your prescription to make you see more clearly. Unfortunately, myopia can develop into glaucoma or cataract. Laser eye surgery may help to correct the condition.

Causes of Mytopia

Medical researchers have not identified the exact cause of myopia, but it could be an inherited condition. A child will become nearsighted if any or both parents are myopic. You might also damage your eyesight depending on the way you use it, due to a hobby or work. If you spend long hours reading a book or text on a computer screen, you might condition your eyes to become shortsighted.

Treatment or Correction

Myopia can be corrected with a concave lens, which moves an image to the back of the retina. This helps to clarify the image. You might opt for contact lenses since they can provide a wider field of view and clearer image than an eyeglass would. However, contact lenses are known to be irritating to some people. They can also cause infection if you use unclean hands.


The opposite of myopia, hypermetropia indicates that your eyesight is too short for its power, or too weak for its length. You will see a blurry picture if you have hypermetropia because the light is not focused on time. Your doctor may prescribe spectacles or contact lenses with a plus power, such as +2.00. This additional power will increase your eye’s focusing strength. Like myopia, hypermetropia increases with age. Thankfully, you are unlikely to be unable to see completely during your normal life because the deterioration are too small to be noticeable.

Causes and Symptoms of  hypermetropia

Besides having difficulty seeing objects that are close, you might experience eyestrain and headaches. This often occurs when you grow older (usually after the age of 38) because your eye has greater capacity when you are still young. Your eyes will become red due to the strain. Dryness and pain in the eyes can also indicate hypermetropia. You will notice someone holding reading material at an arm’s length if he has the condition.

Diagnosis of  hypermetropia

To find out whether you have Myopia and hypermetropia, your doctor may carry out some tests, such as fundoscopy, extra ocular muscle movement, visual acuity and slit

Treatment or Correction

Your doctor may prescribe eyeglasses or contacts with a convex lens, which will move an image forward to bring clearer focus to the retina.

Everyday usage of the terminology
In everyday usage, myopia may mean lack of strategy in life. In politics, for instance, a myopic leader is one who is self-centered and has no long-term plan to transform the fortunes of the community he represents. He might be a person who seeks elective office for personal gain. Hypermetropia is not as commonly used as myopia, but it could mean someone who looks beyond what he should; thus, he might look too far and end up losing focus. It is advisable for you to maintain a moderate vision that enables you to focus and carry out a task effectively.

Myopia and hypermetropia are preventable eye conditions. If you did not acquire any of the conditions genetically, you can prevent it by not engaging in habits that damage your eyesight. Avoid reading for too long especially on a computer screen. Besides having light that could harm your eyes, a computer screen can condition your eyes to focus on close objects only.

Eye experts recommend taking a 20-30 minute break from your reading, and doing eye exercises. For example, you could shift your eyes from the text on your screen or book and focus it on an object or image that is at a greater distance.
