Cloudy vision is a frequent eye condition that results in objects appearing blurred or hazy with reduced sharpness. It may surface in one or both eyes and can emerge over time or occur abruptly. Knowing what causes cloudy vision helps you pursue immediate treatment, including cataract surgery, to keep your eyes functioning at their best. Here are some of the primary causes:
1. Cataracts
Cataracts cause cloudy vision, particularly in older adults. This condition occurs when the eye’s natural lens turns cloudy due to the build-up of protein, which eventually diminishes light transmission. Symptoms include faded colors, difficulty seeing in low-light situations, and sensitivity to glare. The surgery for cataracts involves replacing the cloudy lens with an artificial clear lens and restoring clarity of vision.
2. Dry Eye Syndrome
Dry eye syndrome occurs when tear production decreases below normal levels, or tears evaporate quickly. Patients with this condition experience discomfort, redness, and vision that appears blurred and cloudy. Aging, extended screen time, and environmental conditions contribute to developing dry eye syndrome. Symptoms of dry eye syndrome can be reduced through artificial tears combined with lifestyle changes.
3. Corneal Conditions
The cornea is a layer of the eye that directs incoming light to the retina. Corneal conditions, including keratitis, corneal dystrophies, and scarring damage, can result in cloudy vision. Infection, trauma, and genetic conditions may affect corneal health and require therapeutic intervention. This ranges from medication to corneal transplantation in severe cases.
4. Diabetic Retinopathy
Diabetic patients develop diabetic retinopathy, a condition that destroys the blood vessels within the retina. This eventually leads to fluid leakage, swelling, and cloudy vision. Early detection and managed blood sugar levels can prevent the progression of this issue. Without proper care, extreme diabetic retinopathy may lead to vision loss.
5. Macular Degeneration
Macular degeneration affects the central part of the retina, resulting in blurry or cloudy vision. It is a progressive condition that can make it hard to read, recognize faces, and see fine details. Lifestyle changes, nutritional supplements, and medical procedures can help slow it down.
6. Eye Infections
Eye infections and inflammation, such as conjunctivitis or uveitis, can lead to cloudy vision. Bacterial, viral, or fungal infections may also cause irritation to your eye, resulting in discharge. Antibiotics or anti-inflammatory medications can help clear up such infections and restore your vision.
7. Refractive Errors
Myopia, hyperopia, and astigmatism are typical refractive errors that lead to dull or indistinct vision. Hyperopia makes it challenging to see nearby objects clearly, while myopia causes distant objects to appear blurry. Regular eye exams will help identify and manage these errors, preventing serious vision complications. These eye problems can be resolved with glasses, contact lenses, or refractive surgery such as LASIK.
8. Glaucoma
Glaucoma is a condition that damages the optic nerve due to increased intraocular pressure, leading to cloudy vision. It usually goes unnoticed in its early stages. If left untreated, it may lead to blindness. Eye drops, laser therapy, or cataract surgery are some treatment options that will help preserve vision.
9. Optic Neuritis
Inflammation of the optic nerve is associated with multiple sclerosis or other infections. The inflammation disrupts the transmission of visual signals, resulting in poor eyesight. This condition may lead to cloudy vision, painful eye movements, and temporary vision loss. Although optic neuritis may improve independently, corticosteroids will help reduce inflammation.
