To protect your vision, you must understand both the warning signals your eyes send and the underlying reasons why these problems occur. In medicine, “symptoms” are what you feel, while “causes” are the biological or physical events that create the problem.
Many patients are surprised to learn that a vision problem is not just “bad luck” but the result of specific internal changes or external factors.
Before looking at specific diseases, it is important to recognize the general signs that something is wrong with your eyes.
These are the “alarm bells” of the visual system. While not every symptom means you need surgery, they all require professional evaluation to determine the root cause.
Key warning symptoms include:
Different eye diseases cause specific sets of symptoms. By paying attention to these details, you can help your ophthalmologist identify the cause faster.
Cataracts affect the lens of the eye. The primary symptom is a painless, gradual blurring of vision. Colors may start to look faded or yellowed, like an old photograph. You may find yourself needing much brighter light to read, yet you might also be easily blinded by the glare of oncoming headlights at night.
This condition is painless but terrifying. The symptoms usually happen suddenly. You may see a sudden increase in floaters, followed by bright flashes of light. Finally, a dark shadow or “curtain” may appear to move across your field of vision, blocking out sight.
What actually causes these problems? Why do eyes fail? The causes of conditions requiring eye operations can be grouped into biological, environmental, and medical categories.
The single biggest cause of eye problems is the natural aging process.
Your DNA plays a massive role in the structure of your eyes.
Your eyes are connected to the rest of your body. Diseases that affect your blood and organs often cause severe damage to the eyes.
Diabetes is a leading cause of blindness. The cause is high blood sugar.
Just as high blood pressure damages the heart, it damages the eye. The force of the blood damages the delicate vessel walls in the retina. This can cause “eye strokes” (occlusions) where blood flow is blocked, leading to sudden vision loss.

When to visit he hospital if you experience:
External factors can physically damage the eye structure, leading to the need for operations.
Physical trauma is a direct cause of many surgeries.
Certain necessary medications can, unfortunately, cause eye problems as a side effect.
The primary cause of cataracts is the natural breakdown of proteins in the eye’s lens due to aging. However, trauma, UV radiation exposure, diabetes, and long-term steroid use can also cause proteins to clump together prematurely.
Yes. High blood pressure causes damage to the blood vessels in the retina, a condition called hypertensive retinopathy. It can lead to bleeding in the eye, blurred vision, and even “eye strokes” caused by blocked vessels.
The classic symptoms include seeing a sudden increase in floaters, bright flashes of light (like a camera flash), and a dark shadow or curtain moving over your field of vision. This is caused by the retina peeling away from the back of the eye.
Genetics is a major cause of many eye conditions. Glaucoma, macular degeneration, and corneal dystrophies are often inherited. If your parents had these conditions, your genetic makeup makes you more likely to develop them.
Glaucoma is usually caused by a buildup of fluid pressure inside the eye. This happens when the eye’s drainage system (the trabecular meshwork) becomes blocked or stops working correctly. The high pressure causes mechanical damage to the optic nerve.
