Cause of Minus Eyes

There are many who wonder or do not understand why one should wear glasses, while others have healthy eyes. To know the cause of the eye minus, you must know the basic structure of the eye first.

As it is already known, the eye is like a video camera. When man sees a certain object, there is light entering the eye. This light must pass through four main structures. When the light signal is distorted or damaged, this may result in poor vision.

  

Here are 4 main structures and an explanation of how light affects each structure: 

1. Cornea: This is the point where light comes in. 
2. Lens: Once the light enters the eye, it will meet with the lens, the lens then focuses light on the retina. 
3. Retina: In the retina, light will turn into a neural signal and then the brain will interpret it in the form of an image. 
4. Eyelid: When the eyelid is inflamed, it is possible that the tear producing conduit will be damaged and this condition may affect the tears lining the cornea. When this happens, the vision becomes blurred, which can usually be removed by blinking the eyes.

Eyes are fragile but vital parts of the human body and unfortunately are often ignored. Here is a short list of what may cause poor vision.

1. Genetics: Heredity can be one cause for people with poor vision.
2. Staring and tense eyes: When you stare at something for long periods of time, this causes tension in the eyes. Your eyes need to be moved constantly.
3. Facial expression: frowning, raising eyebrows or even squinting can put a strain on the muscles that control your eyes.
4. Not enough rest: Just like the body, your eyes need rest. Do not diminish your eyes to keep working. Try to rest when eyes getting tired.
5. Stress: Stress is the number one cause of death. So you can imagine the impact caused by stress on your eyesight.
6. Poor eating habits: Eating a healthy and balanced diet is the best way to improve general health.

In addition to the above mentioned, here are some diseases or health disorders that can cause eye disorders and even blindness:

• Myopia. 
• Hyperopia or Rabun close. 
• Cataract. 
• Presbyopia (visual aging)

The above is just a short list of what causes the worsening of vision and the cause of the minus eye.
