# What is dirty lens syndrome?

Dirty lens syndrome refers to blurred vision and discomfort caused by build-up on contact lenses.

## How lens deposits build up

Proteins, oils, makeup, and environmental particles can stick to lens surfaces. Over time, this reduces clarity and may irritate the eye.

- Skipping proper cleaning steps leaves films and debris on lenses
- Sleeping or showering in lenses increases deposit build-up
- Old or damaged lenses attract more deposits
- Symptoms include blur, dryness, and awareness of the lens

## Preventing and managing dirty lens syndrome

Good hygiene and timely replacement keep lenses clear and comfortable. If symptoms persist, an eye examination can rule out other problems.

- Follow the recommended cleaning and replacement schedule strictly
- Rub and rinse reusable lenses with fresh solution each time
- Consider daily disposable lenses if deposits are a recurring issue
- Never use tap water or saliva to clean lenses or cases
