Myopia - Amazing Tips To Tackle It!

What Is Myopia (Nearsightedness)?

Myopia is a common refractive error of the eye that makes it difficult to focus on faraway objects. People who are nearsighted will see objects close to them clearly, while those further away appear blurry. An overall longer shape of the eye usually causes myopia. Nearsightedness tends to run in families, but you don't need to have a myopic parent to develop it. Myopia begins at an early age and worsens in the teenage years, but generally stabilizes in adulthood.

Here are the most common signs and symptoms of myopia:

1. Objects far away, like a chalkboard or road signs, appear blurry
2. Persistent need to squint or close eyelids to see clearly
3. Headaches due to eyestrain
4. Difficulty seeing while driving a vehicle, especially at night (night myopia)
5. Need to sit closer to the television, movie screen or the front of the classroom
6. Holding books very close while reading
7. Not able to notice distant objects

Causes of Myopia

Nearsightedness happens when your eye is longer than normal, or, less often, when your cornea is too curved. It’s a problem in the focusing mechanism of the eyes. However, the exact cause of myopia is not known. Research about myopia supports two key risk factors:

1. Family history. If one or both parents are nearsighted, the chance of their children developing it increases.
2. Working up close. Myopia may be helped along by how a person uses their eyes. Intense detail work, long hours in front of a computer or reading can also increase the chances of developing myopia.

Prevention of Myopia

The prevalence of myopia in children is increasing. This also increases the risk of ocular complications like retinal detachment in high myopes.

Few tips to prevent it are -

• Increase physical activity in outdoor sunlight.
• Low dose atropine.
• Decrease the activities which require focus on near objects only.
• Take a break while doing such activities for long.

Treatment Options for Myopia (Nearsightedness)

When treating myopia, the goal is to help your eyes focus on faraway objects. The most common way to achieve this is through

1. Corrective glasses
2. Contact lenses
3. Refractive eye surgery, such as LASIK, is available for adults and those with moderate to high levels of nearsightedness

Adults who have developed cataracts may also have their myopia corrected with an intraocular lens (IOL) that replaces the human lens during cataract surgery. The most appropriate treatment depends on your eyes and your lifestyle. Nearsightedness can also be corrected as part of the cataract surgery procedure.

1. LASIK: It is an abbreviation for laser in-situ keratomileusis. This is the most common and popular method to correct vision in errors of refraction. In all these conditions (as below), the cornea which is the clear portion in the front of the eye is affected.
2. Phakic intraocular lenses: Also called Phakic IOL, are lenses made of silicone or plastic that are implanted in the eyes permanently to reduce a person's need for glasses or contact lenses. 
3. Contacts and Glasses: Eyeglasses and contact lenses can correct myopia. However, they cannot stop the eye from growing longer or cure the irregular curve of the cornea that causes your blurry vision.
4. Surgery: Surgery can decrease or eliminate dependency on eyeglasses and contact lenses. LASIK surgery is the most common type of surgery to correct myopia.
5. ICL (intraocular collamer lenses) or phakic lenses in adults with cataracts, is an option for those myopic patients who are not suitable for lasik surgery due to either less corneal thickness or very high myopia.
6. Orthokeratology: A new type of treatment that offers an alternative solution to people who are suffering from myopia. Orthokeratology is a process that uses specially designed GP contact lenses to temporarily reshape the contour of the cornea to reduce myopia (nearsightedness).
