Clinically reviewed · Last reviewed 2026-06-13
What it is
A pinguecula is a raised, yellowish deposit on the conjunctiva, the clear surface over the white of the eye. It is very common, harmless, and does not grow onto the cornea, which is what sets it apart from a pterygium.
Common symptoms
Many pingueculae cause few symptoms beyond their appearance.
- A small yellowish raised bump on the white of the eye
- Sometimes redness or irritation, especially in dry or dusty conditions
- A dry or gritty feeling
- No effect on vision
Causes and risk factors
A pinguecula is linked to long-term exposure to ultraviolet (UV) light, wind and dust. It becomes more common with age and in people who spend a lot of time outdoors.
Treatment and self-care
No treatment is usually needed. Lubricating drops ease dryness and irritation, and protecting your eyes from UV light with wraparound sunglasses helps. If a pinguecula becomes very red or inflamed, a clinician can advise on short-term treatment.
