Myopia, do you know the 20/20/20 rule?

There are many risk factors for myopia, but the two most common are:

 

1 / genetics, that is, if the parents are nearsighted, the child tends to be nearsighted too.

2 / excessive practice of certain activities forcing the eyes to work closely, such as reading, embroidery, certain video games. Thus, the eye muscles contract when looking up close but relax when looking at a distance.

 

Therefore, if constant close work is done, for example, using the screen for long hours every day, without a break, the muscles constantly contract. This leads to eye strain. As a result, when looking at a distance, these muscles find it difficult to relax. Muscles become weak and less elastic, resulting in blurred vision at a distance.

 

That is why we recommend reducing indoor activities and increasing outdoor activities. But if you really need to do a lot of screen work or a lot of nearby work, apply the 20/20/20 rule.

 

What is the 20/20/20 rule?

 

Every 20 minutes, take 20 seconds to fix your gaze on objects 20 feet away. Following this rule will help you prevent the rapid development of myopia and eye strain.

 

Knowing that spending too much time in front of a screen can tire the eyes, regular interruptions are advised to rest the sight. Looking away from a screen every 20 minutes to look “into the distance” relaxes the eye muscles, but also helps restore normal blinking frequency, which helps prevent dry eyes.

 

How do you know if you have myopia?

 

Here are the symptoms:

 

  • double vision, blurry, imprecise from afar;
  • frequent squinting to see from a distance;
  • headaches (especially at the end of the day);
  • a tendency to get too close to the television and books.

If you have any of these symptoms, we recommend that you make an appointment with an ophthalmologist. You may need to wear suitable glasses. Why not make an appointment with Patel Optics? Our team is highly qualified to answer all of your questions.
