See into the Future: 5 Causes of Blindness



The gift of sight is a beautiful thing – to be able to see the world, the landscapes and the miniscule expression on someone’s face – it is something that no one would ever want to give up. On this World Sight Day, let’s take a moment and be aware of blindness and what causes it. It is certainly not something that happens to other people but it can happen to you too.

Here are 5 common causes of blindness that we can all be aware of and start finding ways to prevent it:

1. Glaucoma

Glaucoma may sound like a familiar term for an eye disease but what it really is is several eye conditions that can damage the optic nerve. What happens when you have glaucoma is the excess production of fluid in the eye with no channel to release – thus, damaging the optic nerve which can eventually lead to blindness. While there may not be many preventive measures against glaucoma, one can always take note of its symptoms and seek immediate medical help if it occurs such as severe eye pain, blurred vision or redness in the eye.

2. Diabetic Retinopathy

If you have diabetes (Type I or Type II), do take note of this. Diabetic Retinopathy occurs mostly to diabetics and it is caused by the increase of sugar levels in the blood which damages the blood vessels to the retina. In order to prevent this, keeping both your sugar levels as well as blood pressure stable can greatly prevent and slow down the process of diabetic retinopathy.

3. Cataract

Another common term we have all heard of before but what is it really? Basically cataracts form an opaque film over our lens and will cause cloudiness and blocks light from entering our eye. Some of its causes include smoking, heavy drinking, long-term use of steroids and even diabetes. It may be one of those things that come with age, but there are several ways to prevent it such as protecting your eyes from UV rays, eating foods that contain antioxidants and maintain a healthy weight.

4. Age-Related Macular Degeneration (AMD)

As its name states, AMD is most commonly encountered with aging but not entirely inevitable. What happens with AMD is that the macula which aids in reading, writing and noticing small objects, is damaged and causes you to lose a large portion of your central vision. There are preventive ways to lower your risk which you can start paying more attention to now such as taking your multivitamins and stop smoking.

5. Trauma or Injury

While traumas or injuries are a vague explanation for the cause of blindness, it is no less true. If you are in a situation with many sharp objects or dangerous equipment, be sure to guard up and wear your goggles. Take these small preventive measures to ensure your own safety and in case of emergency, seek immediate medical help. Always remember to be careful in these situations and it should play a big role in lowering the risk of trauma-caused blindness.


While we are still healthy and able to read this article, let’s take a moment to thank God for our sight and simply be glad that we can enjoy the sight of our surroundings.
