# What causes foamy tears?

Foamy or bubbly tears often indicate problems with the oily layer of the tear film, usually from eyelid gland dysfunction.

## Typical underlying issues

The meibomian glands in the eyelids produce oils that stabilise tears. When their secretions thicken or become abnormal, bubbles can form.

- Meibomian gland dysfunction related to blepharitis or rosacea
- Chronic dry eye with increased blinking and tear mixing
- Long-term contact lens wear affecting tear quality
- Use of certain eye drops or make-up along the lid margin

## Symptoms and management

Foamy tears often accompany grittiness, burning, and fluctuating vision. Treating the glands improves comfort.

- Warm compresses and lid massage help unblock glands
- Regular lid cleansing reduces inflammation
- Lubricating drops and dietary omega-3s may support tear quality
- Specialist treatments like thermal pulsation are options for stubborn cases
