Experiencing any change in your vision can be a little troubling. If you begin to notice unusual symptoms in regards to your vision, it’s essential to speak to your GP or optician. In many cases, noticing something like cloudy vision could be a sign of an eye condition. The earlier you can see the change, the quicker you can receive the right treatment.

Cloudy vision is sometimes confused with blurry vision, but they are two separate things. While blurred vision is a loss of sharpness and things appear out of focus, cloudy vision is as if you are looking through fog and objects appear milky. It can happen to just one eye or both.

What causes cloudy vision?

Many different eye conditions can cause cloudy vision. If you experience cloudy vision, you might also notice symptoms including double vision, dry or watery eyes, sensitivity to light and redness.

The most common cause of cloudy vision is cataracts. Cataracts are what happen when the lens of the eye gradually becomes cloudy, which can cause visual impairment. It is a by-product of the ageing process, but it can sometimes go unnoticed in the early stages.

Symptoms of cataracts compared to healthy eye

Cataracts surgery involves removing the clouded lens and replacing it. It is one of the most common procedures in the UK.

Another potential cause of cloudy vision is macular degeneration; this is a condition that affects your central vision. It is more likely to cause blurry vision, but in some cases, you might experience clouded vision.

Similarly, diabetic retinopathy, which is a complication of diabetes, may cause cloudy vision. This is due to damaged blood vessels in the retina due to excess blood sugar levels.

Damage to the eye

In most cases, cloudy vision will gradually get worse over time. In some cases, you may experience it suddenly, this could be due to several reasons, including an eye injury. For instance, impact to the eye.

You may experience cloudy vision due to a change or damage to the cornea of the eye, including infections or inflammation.

As cloudy vision can be due to many different reasons, it is important that you visit your optician if you notice any changes in your eyesight. Typical conditions are diagnosed during a routine eye examination, where your optician can advise on the next steps.
