Positive Numbered Glasses for Presbyopia vs. Myopia Prevention

Would using positive numbered glasses while using a computer help prevent myopia?

Wearing positive numbered glasses while using a computer may not necessarily prevent myopia or nearsightedness. Myopia is primarily caused by a combination of genetic and environmental factors such as excessive close-up work, reading, and prolonged exposure to screens.

The purpose of positive numbered glasses, also known as reading glasses or magnifying lenses, is to correct presbyopia, which is an age-related condition affecting the ability to focus on close objects. These glasses help improve near vision for individuals who have difficulty reading or doing close work.

However, myopia is typically caused by the shape of the eye, where the eyeball is elongated, causing light to focus in front of the retina instead of directly on it. Wearing positive numbered glasses would not address the underlying issue of eye elongation and would not directly prevent myopia from developing or progressing.

To help prevent myopia, it is important to practice good eye habits such as taking regular breaks during screen time, maintaining a proper viewing distance from the screen, and ensuring proper lighting conditions. Additionally, spending time outdoors and engaging in activities that involve looking at objects in the distance can help reduce the risk of myopia development. If you are concerned about your vision, I would suggest consulting with an eye care professional who can provide personalized advice based on your specific situation.
