Myopia, which is commonly known as short-sightedness or nearsightedness, is a vision problem experienced by approximately one-third of the population.
People who are myopic have difficulty focusing in the distance, but can see clearly up close. They frequently suffer from headaches and eyestrain, and find themselves squinting when driving or looking at distant objects.
If you are myopic, your glasses prescription will be a negative number (for example, -3.0).
There are important things you need to know about this eyesight problem. Myopia or nearsightedness is one of the common vision problems, afflicting about one third of the population. People suffering from this condition can’t clearly see distant objects without using glasses. Typically, people who are nearsighted can clearly see objects that are up-close but have problems reading signs that are at a distance.
What causes Myopia?
Myopia is a result of the focusing power of the cornea and lens being too strong, which causes the light rays to focus too far in front of the retina. It occurs when the lens or cornea is too curved in proportion to the length of the eyeball.
Symptoms of Myopia
The main symptoms of Myopia normally involve an incapacity to see far away objects. Other symptoms are usually a direct result of trying to compensate for the lack of vision. Here are the common symptoms of Myopia:
- Blurred vision when looking at far away objects
- The squinting or partial closing of the eyes to see clearly
- Headaches as a result of continued squinting
- Trouble seeing at night or while driving
- Excessive blinking
- Needing to hold books close to the face so you can read
- Eye rubbing
A qualified ophthalmologist or optometrist can diagnose myopia during a regular eye examination. In this examination, they are able to determine the severity of myopia and recommend the appropriate treatment. Small children unable to answer screening questions can still be assessed using a retinoscopy, another test which uses reflected light to reach a diagnosis.
How to Correct Myopia
There are treatment options available to Myopia sufferers. Children who do suffer from the condition will normally turn to prescription glasses or contact lenses. Depending on the severity of the condition some people may have to wear glasses or contact lenses permanently to see.
A permanent treatment option which is becoming increasingly popular is refractive laser eye surgery. This surgery eliminates the need for contact lenses or glasses. Perfect Vision offers two types of refractive surgery; iLASIK surgery and Photorefractive Keratectomy (PRK) surgery.
Lens Used For Myopia
If you are myopic, your glasses prescription will be a negative number (for example, -3.0). A negative number means that the lens is concave. Because myopia sufferers retinas are too strong, the light rays focus in front of the retina as they enter the eye. A concave lens moves the images to the back of the retina which brings long distance objects into clear focus.
