Lazy eye – causes, symptoms, and treatment methods
What is lazy eyes?
Lazy eye is a condition that affects one (or both) eyes when vision does not develop normally during childhood. This occurs when the optic nerve is not stimulated enough, resulting in permanent impairment of vision, even with glasses or contact lenses.
This problem usually appears in the first years of a child's life, and may not be easily noticeable without periodic visual examinations. If lazy eye is not treated in time, the problem may last a lifetime, affecting the quality of vision and the ability to clearly determine dimensions. Therefore, it is recommended to detect early signs of poor vision in children to ensure effective treatment and improve their vision development.
Causes of lazy eyes
Lazy eyes can result from several factors, including:
- Squint: When one eye is not compatible with the other, the brain relies on the stronger eye and neglects the other.
- Uncorrected visual defects: Such as nearsightedness, farsightedness, or astigmatism, which may affect one eye more than the other.
- Obstruction of vision in the eye: Due to cataracts or drooping eyelids, which prevents the normal development of vision.
