Know the basics
What is nearsighted?
Nearsightedness, also known as myopia, refers to the vision condition in which you can not see objects farther away but objects near to you clearly. When you are nearsighted, you can find it difficult to see distant objects. For instance, you can not be able to make out highway signs until they are just a few feet away. This condition can progress gradually or rapidly, often become worse during childhood and adolescence.
How common is nearsighted?
This health condition is common in people between the ages of 8 and 12 but it can affect patients at any age. It can be managed by reducing your risk factors. Please discuss with your doctor for further information.

- If you experience a sudden onset of flashes of floaters or a shadow covering part of your field of vision.
Know the causes
What causes nearsighted?
You nearsightedness can be caused by the fact that your eyeball is too long or has a cornea that is curved too steeply, meaning that instead of focusing in the retina, light rays enters each eye to focus in front of the retina and this leads to blurry images.
Know the risk factors

How is nearsighted diagnosed?
You can be diagnosed with nearsightedness through an eye exam. In a complete eye exam, you may need to experience a series of tests. Your eye doctor may use various instruments, aim bright lights directly at your eyes and ask you to look through several lenses. The gold of these tests is to detect different aspects of your eyes and vision and to identify what prescription you may need to have clear vision with the help of eyeglasses or contact lenses.
How is nearsighted treated?
To treat nearsightedness, you need to improve your vision through helping to focus light on your retina with the help of corrective lenses or refractive surgery.
If you choose to wear corrective lenses for treating your nearsightedness, it can help you by counteracting the increased curvature of your cornea or the increased length of your eye. You can try eyeglasses with many typles like bifocals, trifocals and reading lenses; or contact lenses that are worn right on your eyes.
If you don’t like the feeling of wearing something to help with your nearsightedness, you can consider refractive surgery. This method helps you to decrease or even eliminate your dependence on glasses or contact lenses. The most common procedures are photorefractive keratectomy with the use of a laser to remove a layer of corneal tissue, and laser-assisted in situ keratomileusis with use of a femto laser or mechanical instrument to cut a thin flap through the top of the cornea.
Lifestyle changes & home remedies
What are some lifestyle changes or home remedies that can help me manage nearsighted?
The following lifestyles and home remedies might help you cope with nearsighted:
- Check your eye regularly;
- Control chronic health conditions, such as diabetes and high blood pressure;
- Protect your eyes from the sun by wearing sunglasses that block ultraviolet (UV) radiation;
- Prevent eye injuries. It is suggested that you should wear protective eyewear when doing certain things like playing sports, mowing the lawn, painting or using other products with toxic fumes;
