Short-sightedness, also known as myopia, is a common refractive error of the eye that causes distant objects to appear blurry, while close-up objects can be seen clearly.

There are several factors that contribute to why most people are short-sighted:

1. Genetic Factors:

Myopia tends to run in families, suggesting a strong genetic component. If one or both parents have myopia, their children are more likely to develop it as well. Certain genes may make individuals more susceptible to developing short-sightedness

.2. Environmental Factors:

Changes in lifestyle and increased use of screens may play a role in the rising prevalence of myopia. Spending long hours indoors and engaging in activities that require constant close-up focus (e.g., reading, using computers, smartphones, and other digital devices) can strain the eyes and potentially contribute to myopia development.

3. Lack of Outdoor Time: Studies have found that spending more time outdoors, especially during childhood, is associated with a reduced risk of myopia development. Natural light and focusing on distant objects may help protect against myopia.

4. Urbanization and Education: The prevalence of myopia tends to be higher in urban areas compared to rural regions. Additionally, individuals with higher levels of education often have a higher risk of myopia. The intense near-work associated with education and urban living may be contributing factors.

5. Increased Screen Time: The widespread use of digital devices, especially among younger populations, may contribute to the development of myopia. Prolonged screen time can cause eye strain and may influence the development of short-sightedness.

6. Changing Demographics: As the world’s population becomes more urbanized and technologically connected, the prevalence of myopia has been increasing in many parts of the world. It’s important to note that while these factors contribute to the development of myopia, the exact causes are not fully understood, and it is likely a complex interplay of genetics and environmental factors. Regular eye check-ups and following eye-care recommendations, such as taking breaks during prolonged close-up work, can help detect and manage myopia effectively. If you’re concerned about your vision, it’s best to consult an optometrist or ophthalmologist for a comprehensive eye examination.
