Long-sightedness, also known as hyperopia, is a common refractive error that affects the ability to see nearby objects clearly. In young people, the cause of long-sightedness can be attributed to several factors:
1. Inherited Factors: Long-sightedness can be hereditary, meaning it can be passed down from parents to their children. If one or both parents have hyperopia, there is a higher chance of their children developing it as well.
2. Eye Shape: The shape of the eye plays a role in long-sightedness. In hyperopia, the eyeball is shorter than normal or the cornea (the clear front surface of the eye) is flatter than usual. These structural differences affect how light is focused on the retina, leading to difficulty in seeing nearby objects clearly.
3. Age-related Changes: Some young people may experience temporary long-sightedness due to age-related changes in the lens of the eye. The lens loses its flexibility and ability to focus on close objects, resulting in hyperopia. This condition is known as "accommodative hyperopia" and can improve as the lens becomes less flexible with age.
4. Eye Fatigue: Excessive near work, such as reading or using digital devices for extended periods, can strain the eyes and contribute to long-sightedness. Prolonged focusing on close objects can cause the eye muscles to become fatigued, leading to difficulties in focusing on nearby objects.
It is important to note that the exact cause of long-sightedness can vary among individuals, and a combination of these factors may contribute to its development in young people. Regular eye examinations by an optometrist or ophthalmologist can help diagnose and manage long-sightedness effectively.
