The ability to see clearly is a precious gift that we often take for granted. Unfortunately, millions of people worldwide suffer from poor eyesight, and this can significantly impact their daily lives. In this blog, we will explore the various factors that can lead to bad eyesight.


  1. Genetics:

One of the primary causes of bad eyesight is genetics. If your parents or close relatives have poor eyesight, there is a higher chance that you may also develop similar issues. Conditions like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are all hereditary. These conditions occur due to a variation in the shape or size of the eyeball, cornea, or lens. This leads to difficulties in focusing on objects at various distances, leading to blurry vision.
  1. Excessive eye use:

Staring at items such as computers, cell phones or books for long periods of time can cause excessive force on the glasses, which can easily cause eye fatigue and dryness, which in turn can affect vision.
  1. Age factor:

As we age, the adjustment ability of the eyes will gradually decrease, and the phenomenon of presbyopia will appear, making it difficult to see items at close range clearly.
  1. Eye diseases:

Certain eye diseases such as glaucoma, cataracts, and retinal detachment can also cause vision loss.
  1. Environmental factors:

Environmental factors may also have an effect on vision, such as insufficient light and overexposure to ultraviolet light.
  1. Chronic lack of nutrition:

Malnutrition and long-term lack of vitamins and other nutritional elements can also have an adverse effect on vision.

Prevention of poor vision

  1. Cultivate good living habits:

Both students and office workers need to ensure that they have sufficient sleep and rest time in their daily lives as well as at work, and do appropriate outdoor activities to be able to rest their eyes. In general, people should go to bed early and get up early, as far as possible not to stay up late. You can do more outdoor activities and participate in sports to prevent your eyesight from being affected.
  1. Insist on doing eye exercises:

Eye exercises can effectively protect their eyesight and play a role in preventing myopia. So even after going to college or working, people should continue to do eye exercises to protect their eyesight.
  1. Regular vision examinations:

Only regular vision checkups can promptly detect changes in your vision and whether it has decreased, and when it does, you need to promptly choose effective measures, such as eye drops and enhanced eye rest time, to relieve your vision fatigue.
  1. Timely supplementation of nutrition:

When vision loss occurs, you should pay more attention to your diet, a healthy and reasonable diet, and more protein. In addition, to prevent vision loss again, you should supplement more calcium and phosphorus. Calcium and phosphorus can make the sclera tougher and participate in the physiological activities of the optic nerve.
  1. Pay attention to eye hygiene in general:

Do not rub your eyes with your hands
