Myopia is the most common vision problem in people of all ages, and it is on the rise in many countries around the world, especially in young children and school-age children. So let's get to know and understand myopia so that everyone can have the knowledge and care for your eyes and your loved ones properly.
What is Myopia?
Myopia is a type of vision disorder in which the lens of the eye cannot receive the light refracted from the object that sends the image to fall before the retina, making the retina unable to send the image to the brain for processing clearly. People with myopia can see objects in the distance blurry or see images indistinctly. Some people have headaches and pain in the eye sockets, but they can see objects up close clearly, causing squinting or squeezing of the eye muscles to focus the eyes to see what the distant image is.
How does myopia occur?
First, you need to understand that the human vision system is caused by light hitting an object and then reflected into our eyes through the lens (Lens) into the eyeball and falling on the retina. Or creating an image on the retina (Retina) and sending information about the object being seen through the nerve (Optic nerve) will be sent to the brain. Let the brain analyze the light and image to translate the information that the image we are seeing is what.
The common type of myopia is caused by the cornea being more curved than normal or the diameter of the eyeball is longer than normal, so it has more refractive power. This makes the focal point of the image of the distant object fall before the retina, making it difficult to see in the distance. Or it may occur due to risky behaviors such as using the eyes too much, especially for computer workers or those who read books for a long time.
Signs that it is a state of myopia
- See things in the distance blur or see them unclearly.
- Have to stare or focus on near objects, squinting and closing one eye to see more clearly.
- Experience eye fatigue when you have to focus on things that are far away, which may lead to headaches.
- See things unclearly when driving, especially at night, or called night myopia.
How can I take care of my eyes when I have it?
If you feel that you are experiencing the symptoms mentioned above, it is recommended to have your eyes checked with the BVAX system for up to 16 steps to know the cause of the problem. For those with myopia, you can choose to wear glasses only, or wear glasses alternately with contact lenses, or if you want to have LASIK, you can do so as well. This is a way that we can see normally again, but it is not possible for everyone, especially those with thin corneas or those with keratoconus.
For some people with night myopia, it can be corrected by wearing glasses at night or in low-light conditions. Use lenses with a multi-coat coating to cut out distracting glare and allow more light to enter the eye, resulting in improved night vision. In addition, yellow-tinted lenses can help reduce the effects of night myopia, but they can distort the color of objects, so they should be used with caution and under the care of a specialist.
