Is it Genetic to be Near-sighted, Far-Sighted or Astigmatic?

When the cornea and lens can focus clearly onto the retina, it means that the eye has perfect near and distance vision. Even though the human body has evolved incredibly well, it has some serious design flaws. The most evident example of this is the rate at which our vision deteriorates with age. More and more people are getting affected due to an increased reliance on technology and electrically operated gadgets.

Nearly 2/3rd of the adult population wears prescribed eyewear, and 20% uses contact lenses but both glasses and lenses have their own limitation. Near-sightedness, far-sightedness and astigmatism are refractive errors that make it difficult for the eyes to focus. In some cases, these vision conditions can be present at birth or it can be the environmental conditions, eye injury or eye surgery which has been done previously.

What is Myopia?

Myopia or Near-Sightedness occurs when light cannot focus on your retina causing faraway objects to appear unclear or blurry. It happens when the eyeball is too long or when you have a cornea which is curved too much. Myopia often begins before you enter your teenage years. Heredity and environmental factors can also be the cause of short sightedness.

What is Hyperopia?

Hyperopia or Far-Sightedness is when the eyeball is too short or the cornea is curved too little. For people suffering from hyperopia, objects that are closer appear to be blurry while distant objects appear clearly. This can cause headache, eye strain and fatigue while doing meticulous work. Severe hyperopia can result in blurred distant vision. Sometimes when it’s just very benign, the eyes may focus without corrective lenses.

What is Astigmatism?

Astigmatism is an eye condition where the cornea is oval shaped, and objects cannot focus properly on the retina causing two focal points. This not only causes blurred vision but also distorts it. People suffering from astigmatism experience eye-strain, headaches or blurred vision at a certain distance. It can be genetic but environmental factors can also add onto the problem.

The problem increases very slowly over time, but it remains relatively stable. The symptoms of astigmatism include: blurry vision, headaches and horizontal direction of objects appear unclear. It may appear like a flash or blaze around the object.

Treatment Options

Glasses and contact lenses usually offer clear vision and relieve symptoms. Most people who wear glasses suffer from Myopia, Hyperopia or Astigmatism. People suffering from these vision disorders can consider LASIK eye surgery. Since it’s by far the safest and most frequently performed corrective eye surgery which reshapes the cornea enabling proper focus of light through the retina. \

The surgery is conducted by trained ophthalmologists who create a small notch to access the inner tissue of the cornea and gently reshape the eye’s curvature to correct the degeneration.

Inherited diseases can be cured if they’re discovered and diagnosed early on. We need to take care of our eyes which we usually take for granted for most of the time. LASIK eye surgery is a quantum leap in curing vision related issues by modern medical science. It is a quick and painless process which helps you get rid of your boring glasses and irritating contact lenses.
