A person with nearsightedness can see close objects clearly, but may have trouble seeing objects from a distance – like a road sign, blackboard, or face across the room. It’s a common condition, affecting 1 in 4 adults worldwide.
What Causes Nearsightedness?
Nearsightedness or myopia happens when the eye has a long shape, which causes light rays to focus too far in front of the retina, making distance vision difficult.
Like farsightedness, myopia can be inherited. It is often discovered when children are 8 to 12 years old. During the teenage years, when the body is growing rapidly, nearsightedness can get worse. Typically, between ages 20 and 40 there is little change.
Symptoms of Nearsightedness
An eye care professional can diagnose nearsightedness with a simple eye exam. The most common symptoms of nearsightedness include:
- Blurred distance vision
- Frequent squinting of eyes
- Eye strain or headaches from trying to focus
Treatments for Nearsightedness
Nearsightedness is easily corrected by refocusing the light rays onto the retina of the eye. This is commonly done through:
- Eyeglasses and contact lenses: The simplest treatment option chosen by most patients with nearsightedness. PureVision2 contact lenses deliver the clear, crisp vision that you should demand – designed to reduce halos and glare – especially in low light.
- Vision Shaping Treatment (Orthokeratology) – an innovative process that uses customized shaping lenses to gently correct your vision while you sleep so you can enjoy clear vision while you’re awake.
- Surgery: Surgical options are available, but can be expensive, and may involve more risk than contact lens options available. These procedures use laser technology or manual incisions to remove small amounts of tissue from the cornea.
