Myopia, or short-sightedness, describes the inability to see objects in the long distance. Myopia causes the length of the eyeball to elongate more than normal. This causes an imprecision of the transmission of light to the retina at the back of the eye. When the light is not transmitted onto the retinal surface precisely, the image of an object far away is consequently blurred. To see clearly, a person with myopia has to correct their vision, either through spectacles, contact lenses or surgery.
Myopia is commonly caused by continued near or close work. This may include reading, using technological devices, studying, needlework. As a result, the person’s distance vision is blurry. An Australian study in 2003 also found that the prevalence of myopia increased, if a child was kept indoors for most of their young life, suggesting that myopia is caused by a lack of sunlight exposure. General poor health, poor diet and poor sleep may also be contributing factors that cause myopia.
Myopia is a condition that should be taken seriously, and managed at a young age. If it is not managed, and progresses to higher prescriptions, at an older age, the individual poses a higher chance of developing ocular diseases which will lead to permanent vision loss. This includes retinal detachment, glaucoma and macular degeneration.
To treat myopia, there are a number of control treatment including:
- Prescription glasses
- Prescription contact lenses
- Atropine drops
