Blurred vision can have various underlying causes, some of which may require immediate medical attention. Here are seven potential causes:
Refractive Errors
Conditions such as nearsightedness (myopia), farsightedness (hyperopia), or astigmatism can cause blurred vision.
Presbyopia
As people get older, the natural lens in the eye loses flexibility, making it difficult to focus on nearby objects and leading to blurred vision.
Dry Eyes
When the eyes do not produce enough tears or the tears evaporate too quickly, it can cause dryness and irritation, resulting in blurred vision.
Cataracts
Cataracts occur when the lens of the eye becomes cloudy, leading to blurred or hazy vision. This is often age-related but can also be caused by other factors such as injury or certain medications.
Glaucoma
Glaucoma is a group of eye conditions characterised by increased pressure within the eye, which can damage the optic nerve.
Eye Infections
Infections such as conjunctivitis (pink eye) or keratitis can cause blurred vision, along with symptoms like redness, itching, discharge, and sensitivity to light.
Diabetes
People with uncontrolled diabetes may experience blurred vision due to changes in the blood vessels of the retina, a condition known as diabetic retinopathy.
Conclusion
Again, it's essential to consult with a healthcare professional to determine the exact cause of your blurred vision and receive appropriate treatment.
