What Causes Blurry Vision? Common Causes and Treatment
Blurry vision is a common eye problem that can affect people of all ages. You may notice that objects appear unclear, reading becomes difficult, or distant objects look hazy. While blurry vision can sometimes result from temporary eye strain, it may also indicate an underlying eye condition that requires medical attention.
Common Causes of Blurry Vision
Refractive Errors
Conditions such as myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism occur when the eye does not focus light correctly on the retina. This can make nearby or distant objects appear blurred or distorted. Common symptoms include difficulty reading, seeing road signs or focusing on objects clearly. Prescription glasses, contact lenses or suitable vision correction procedures can help improve clarity.
Dry Eyes
Dry eye occurs when the eyes do not produce enough tears or when tears evaporate too quickly. This can cause fluctuating vision, irritation, redness, a burning sensation or a gritty feeling in the eyes. Symptoms may become more noticeable during prolonged screen use, reading or exposure to air conditioning. Appropriate eye drops and advice from an eye specialist can help manage the condition.
Cataracts
Cataracts develop when the eye’s natural lens becomes cloudy, gradually affecting the clarity of vision. People may experience blurred vision, glare from bright lights, difficulty driving at night or faded colours. Symptoms usually develop slowly and can interfere with everyday activities. Cataract surgery may be recommended when vision loss begins to affect daily life.
Diabetes-Related Eye Problems
Diabetes can damage the tiny blood vessels in the retina, leading to diabetic retinopathy and other vision-related complications. Symptoms may include blurred vision, dark spots, floaters or difficulty seeing clearly. Some diabetic eye conditions can progress without noticeable early warning signs. Regular comprehensive eye examinations and proper diabetes management are essential to help protect vision.
Glaucoma and Other Eye Conditions
Glaucoma is a group of eye diseases that can damage the optic nerve, sometimes due to increased pressure inside the eye. It may develop without obvious early symptoms and can gradually affect peripheral vision. Other eye conditions may also cause blurred vision or changes in visual clarity. Regular eye examinations can help detect these problems early and reduce the risk of permanent vision loss.
Age-Related Macular Degeneration (ARMD)
Age-related macular degeneration affects the macula, the part of the retina responsible for sharp central vision. It can make reading, recognising faces and seeing fine details increasingly difficult. Some people may notice straight lines appearing wavy or a blurred or dark area in their central vision. Early detection and appropriate treatment or monitoring can help preserve vision, depending on the type and stage of the condition.
Corneal Diseases
The cornea is the clear front surface of the eye that helps focus light for clear vision. Conditions such as corneal infections, scarring and keratoconus can affect its shape or transparency, resulting in blurred or distorted vision, glare and light sensitivity. Symptoms may vary depending on the underlying condition and its severity. Early assessment by an eye specialist is important to identify the cause and determine the appropriate treatment.
When Should You Seek Medical Attention?
Sudden blurry vision should never be ignored, especially if it occurs with severe eye pain, flashes of light, new floaters, a dark shadow in your vision, weakness or difficulty speaking. Seek emergency medical attention for these symptoms.
How Is Blurry Vision Treated?
Treatment depends on the underlying cause. An eye specialist may recommend prescription glasses, suitable eye drops, medical treatment or surgery, depending on the diagnosis. Avoid self-medicating with eye drops without professional advice.
