Myopia: causes, signs, symptoms and prevention – Tips & Results

Nearsightedness, or short-sightedness, is a condition in which you can see objects that are close to you clearly, but objects that are farther away appear blurry. Myopia can develop gradually or, in some cases, appear quickly. It often gets worse in childhood and adolescence. Myopia is a common vision disorder that tends to run in families.

Diagnosing myopia is not difficult as it can be confirmed with a simple eye exam. Myopia can be corrected with glasses or contact lenses. Another option offered by doctors these days is Lasik surgery. People with myopia may have trouble watching television or looking at the blackboard at school. Myopia usually occurs when the eyeball is too long or the cornea is too curved. As a result, the light entering the eye is not properly focused, causing distant objects to appear blurry.

Those who spend a lot of time reading, working on computers, or doing other visual work are more likely to develop myopia, although the condition can be inherited. Although the most common symptom of myopia is blurred vision, other symptoms such as headaches, squinting, eyestrain, eye fatigue, or an inability to see distant things at a distance can help in the diagnosis. There is no way to prevent this condition, as prescribed in many studies conducted on myopia.

Myopia can have many complications, including:1. Reduced Quality of Life: This means you may not be able to perform certain tasks and may also be a major obstacle in completing everyday tasks.2. Eyestrain: You can cause eyestrain by squinting your eyes to read or observe a particular panel or sign.3. They may be exposed to other eye problems such as glaucoma, retinal detachment, and cataracts.

myopia causes

An international team of scientists led by King’s College London have discovered 24 new genes that cause refractive errors and myopia (short-sightedness). These findings appear in the journal Nature Genetics, revealing genetic causes of the trait and leading to better treatments or ways to prevent it.

Up to 80 percent of Asians suffer from myopia. As vision develops, the eye lengthens, but in myopes it becomes too long, and light entering the eye is then focused in front of the retina rather than on it. This leads to a blurred image. Myopia is hereditary, although little was known about its genetic background.

“We already knew that myopia runs in families, but until now we knew little about the genetic causes. This study reveals for the first time a group of new genes associated with myopia and that carriers of some of these genes have a 10-fold increased risk of developing myopia,” said lead author Chris Hammond.

“Currently, myopia is corrected with glasses or contact lenses, but now that we understand more about the genetic triggers for the condition, we can start exploring other ways to correct it or prevent it from progressing. ”

Researchers have shown that when working with smartphones for a long time, users, especially teenagers, tend to hold it closer than usual – between 10 and 12 inches. Doing this in excess can lead to myopia, especially if you are prone to it. Global reports show a 35% increase in young patients with progressive myopia, which many leading journals have attributed to near-point activity on a smartphone. These problems are exacerbated by the daily use of computers,” says eye surgeon Dr. Keiki Mehta.

myopia symptoms

Myopia is usually diagnosed in early school years or the teenage years because teachers are the first to notice spelling mistakes when students are copying from the blackboard.

Symptoms of myopia can include:

1. Blurred vision when looking at distant objects

2. You must partially close or squint your eyes to see clearly

3. Frequent headaches due to eyestrain

4. Difficulty driving at night is also known as nighttime myopia

5. You need to sit closer to the TV, screen or blackboard

6. Blinking and excessive rubbing of the eyes

7. Holding a book very tightly while reading

8th. Your eyes feel constantly tired and strained.

9. Eye fatigue when trying to see more than a few feet away

10 Strain your eyes when focusing on distant objects

Certain medical conditions, such as diabetes, can increase your risk of myopia or make your condition worse if you already have it.

Prevention of myopia

“Smartphones have become so ubiquitous that to even say you can do without them would be to deny the obvious benefits. However, one can reduce the time spent with these devices, it is best to buy a device with a larger screen and only do the bare minimum quantity of work on a 4-inch screen and limit daily email activities to that Sitting in front of a bigger screen, where the risk of overexertion is significantly reduced,” says Dr. Keiki Mehta.

“Those who use cell phones extensively should limit their use. Take regular breaks and try to keep your distance from your phones. Blink more often too, as this will keep your eyes from drying out. Reading black letters on a white background can reduce eye strain. Increasing the font size is also a must,” adds Dr. Added Zenobia Shroff.

1.The best way to prevent myopia is to catch it early.

2. Myopia can be prevented by using “Plus-Power” glasses.

3. Using mandatory reading glasses for extended periods of screen time relaxes muscles and can therefore reduce or prevent the risk of myopia.

4. For close-ups, try to hold the subject as far as possible.

5. Reducing screen time and eating a diet rich in vitamin A can significantly reduce your chances of developing myopia.

6. In addition to glasses, myopia can also be corrected with lenses and eye surgery.

7. Studies have now shown that therapeutic contact lenses worn by children can actually prevent their eyes from becoming too long and thus preventing myopia!

Some visual hygiene measures are often recommended, including:

1. Take a break every 30 minutes when working on the screen

2. Keep the right distance from the book while reading

3. Pay attention to sufficient lighting

4. Visual work should be done in a relaxed, upright posture

5. Limit the time you spend watching TV.
