Medical Video: What is Nearsightedness? What Causes Myopia?
Are you having trouble seeing distance? If so, maybe you experience nearsightedness (miopi) or often called minus eye. In order to see clearly, you need the help of a minus lens. Many say if the cause of the minus eye is like reading or watching television too close. There are also those who say because they like reading in dimly lit rooms. So what exactly is the cause of the minus eye? Is that true?
What are the causes of minus eyes?
In the normal eye, to be able to see an object, the image of the object captured by the eye must be captured by the retina. However, in people who experience nearsightedness, this shadow does not fit to fall on the retina, but in front of it. Finally makes the eyes look blurry.
Until now it is not certain what made nearsightedness occur. However, experts conclude that a person's minus eye can be due to genetic and environmental influences. Yes, the combination of the two makes you finally difficult to see objects at a distance. Experts say that there are a number of risk factors that might make you experience far-off, namely:
1. Genetic
If one of your parents has nearsightedness, then your chances of getting this condition are also greater. The greater the risk if both your parents both have minus eyes. Until now, the study stated that there are 40 genes that cause nearsightedness.
2. Reading habits
Although not a major cause of minus eye, reading habits affect your risk. Yes, if you are a person who likes to read, myopic risk is far greater than other people who rarely read. Especially if you often read in a dim place and the distance is too close to your eyes.
3. Rarely do outdoor activities
There are several studies that state that nearsightedness can also be caused by rarely doing outside activities that affect eye health. Because the level of light in the room with outside is certainly different.
4. Always use your eyes at close range
If you have a habit of writing, reading, and playing gadget too close to the eyes, this can increase the risk of nearsightedness. So, you should get used to reading or writing from a distance of about 40 centimeters (cm) from the screen or book.
Can the minus eye be prevented?
Because the main cause of the minus eye is unknown, you can only reduce the risk. Some things that can reduce the risk of eye minus like:
- Not reading, writing, and looking at a very close view.
- Frequent outdoor activities.
- If your eyes get tired, rest your eyes first, don't force them.
- Avoid reading and writing in a dark or poorly lit place.
Usually, minus eyes begin to occur during childhood and stop during adolescence. However, not everything will be like that. Not infrequently also this disorder lasts into adulthood. If indeed you begin to feel that you have signs of nearsightedness, you should immediately see a doctor. Symptoms not only cannot see far away, but also symptoms like:
- Frequent headaches and dizziness
- Eyes get tired quickly
- Eyes feel tense
If this happens, you should immediately consult an ophthalmologist. The most common treatment to treat this condition is by giving a minus lens. You can also choose to do LASIK, which is a surgical procedure with a laser to correct your minus.
