Myopia

If someone is nearsighted, they will be able to see nearby objects clearly, but distant objects will appear blurry without the use of corrective glasses or contact lenses. It is a very common eye condition.
The severity of myopia varies among individuals, from mild cases that do not require treatment to severe cases that can significantly impact vision. Myopia typically starts between the ages of 10 and 13 but can also occur in younger children. It usually worsens during adolescence and stabilizes around the age of 20 when growth stops.

Symptoms of myopia in children may include sitting close to the TV, needing to sit in the front rows at school, frequent eye rubbing, and complaints of eye strain or headaches. Similarly, symptoms of myopia in adults include difficulty reading distant objects like traffic signs, headaches, eye strain, and squinting to focus better.

It is recommended to have regular eye exams every two years.

Myopia is a focusing problem of the eye that occurs when the eye grows too large, causing a mismatch between the focus point of the eye's lens and the position on the retina where images are focused. Light passing through the lens does not focus properly on the retina due to the elongated eye shape. This results in light focusing in front of the retina, making distant objects appear blurry.

The exact cause of myopia is not fully understood. In some cases, it runs in families. Myopia has also been associated with spending extended periods focusing on nearby objects during childhood.

 Myopia can usually be corrected with prescription glasses or contact lenses that use concave lenses to move the focus of light back onto the retina for clear vision. Laser eye surgery is also an option once the progression of myopia stabilizes.
