A person with shortsightedness 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 Shortsightedness?
Shortsightedness 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 Longsightedness, 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, it can get worse. Typically, between ages 20 and 40 there is little change.
Symptoms of Shortsightedness
An eye care professional can diagnose shortsightedness with a simple eye exam. The most common symptoms include:
Treatments for Shortsightedness
Shortsightedness is easily corrected by refocusing the light rays onto the retina of the eye. This is commonly done through:
Spectacles and contact lenses: The simplest treatment option chosen by most people.
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.
