There are many possible reasons for cloudy vision, including:
Slow progressing chronic eye conditions
- Cataracts: Cataracts are a common cause of cloudy vision, especially in older adults. They occur when the clear lens inside the eye becomes cloudy, making it difficult to see clearly. Cataracts normally progress over a number of years before requiring surgical removal.
- Age-related macular degeneration: This is a condition that affects the macula, the central part of the retina, which is responsible for sharp, detailed vision. As the macula degenerates, vision can become hazy or blurry particularly central vision.
- Glaucoma: This is a group of eye diseases that can cause damage to the optic nerve, which is responsible for transmitting visual information from the eye to the brain. If left untreated, glaucoma can lead to permanent vision loss.
Acute sudden onset eye conditions
- Dry eyes: If your eyes don’t produce enough tears, or if the tears evaporate too quickly, it can cause dry, itchy, and irritated eyes, which can also lead to blurry or hazy vision. Lubricating eye drops can assist in managing this condition.
- Eye infections: Infections such as conjunctivitis (pink eye) or uveitis (inflammation of the middle layer of the eye) can cause cloudy vision mainly due to disruption of the tear film and mucous discharge. Antibiotics and lubricating eye drops may be required.
- Diabetes: Diabetes can cause a number of eye problems, including diabetic retinopathy, which can lead to cloudy or blurry vision. This can be sudden onset due to macula oedema or slow progressing due to changes in prescription and may fluctuate.
- Retinal tear or detachment: Common symptoms include flashes of light or new floaters in the vision which may make your vision appear cloudy. These symptoms should be assessed by a health professional as soon as possible as delayed treatment may result in permanent vision loss.
If you are experiencing cloudy vision, it is important to see an eye doctor for a comprehensive eye exam to determine the cause and appropriate treatment.
