Pinguecula: What It Is and How to Protect Your Eyes
March 22, 2025

A pinguecula is a harmless, noncancerous growth on the conjunctiva, the clear tissue covering the white of the eye, often seen as a yellowish-white bump. Though it can occasionally appear on the outer, it typically develops on the side of the eye closest to the nose. Pingueculae (plural) are protein, fat, or calcium deposits that develop due to long-term environmental exposure, particularly dust, wind, and sunlight, and are commonly linked to this change. Under these conditions, the conjunctiva’s elastin fibers may gradually degrade.
Although these growths are normally harmless and do not impede vision, they can occasionally cause dryness, redness, and irritation, particularly if they alter the natural distribution of tears. Pingueculae rarely pose severe problems, but they don’t go away independently and may grow somewhat with time. As people age, pingueculae become more prevalent due to accumulated exposure to risk factors. Pingueculae in both eyes are more common in people who spend a lot of time outside, especially in abrasive environments.
Causes
Pinguecula typically develops due to prolonged exposure to environmental factors that irritate the conjunctiva. Over time, this irritation triggers the formation of a raised, yellowish growth. Common causes include:
- UV Radiation: Frequent exposure to sunlight, particularly without proper eye protection, is a leading cause. The sun’s ultraviolet (UV) rays can gradually damage the conjunctiva, increasing the risk of pinguecula formation.
- Environmental Irritants: Wind, dust, and sand can irritate the eyes, contributing to the development of pinguecula. People who spend a lot of time outdoors are more susceptible.
- Occupational Hazards: Certain jobs, such as arc welding, carry a higher risk due to intense light exposure and eye irritation.
- Aging: Pingueculae are more common in older adults, as years of environmental exposure gradually affect the eyes.
Although the exact cause is not always identifiable, reducing exposure to these triggers can help lower the risk of developing a pinguecula.
Prevention and Treatment
Pingueculae can be prevented by protecting your eyes from environmental factors and UV radiation.
- Use sunglasses to shield your eyes from harmful sun exposure. Opt for sunglasses that shield your eyes from both UVA and UVB rays. Additionally, sunglasses shield your eyes from dust, wind, and other particles.
- Use Artificial Tears (eye drops) to prevent dryness and irritation. Keep your eyes moisturized. If you use eye drops more than four times per day, choose preservative-free versions to avoid irritation.
- When working in dry, dusty, or windy situations, wear appropriate eye protection.
These precautions help reduce the risk of getting pingueculae, especially for those who spend much time outside for work or recreation. Surgical removal entails removing the growth and replacing it with healthy conjunctiva or other eye tissue. This is usually reserved for cases of chronic inflammation, visual impairment, or cosmetic issues. Most pingueculae are innocuous and will not go away on their own, although therapy can help manage symptoms when necessary.
Even while pingueculae are usually harmless eye problems, they might cause irritation or complications that must be addressed. You can protect your eye health by understanding the causes, symptoms, and potential treatments. Simple actions like avoiding irritants, drinking enough water, and wearing UV-blocking eyewear can help preserve eye comfort while preventing the growth of pingueculas. If you are experiencing persistent discomfort or vision difficulties, consult an eye specialist to determine the best course of action. Keep in mind that keeping your vision and overall eye health demands prompt action.
Frequently Asked Questions
1. What happens if my pinguecula keeps growing?
Rarely does a pinguecula continue to grow until it forms a unique growth known as a pterygium. A pterygium is just a more aggressive version of a pinguecula. It grows faster and has a raised, wedge-shaped look with visible blood vessels. It can occasionally spread throughout your cornea and compromise your vision.
2. When should I see an eye care provider about my pinguecula?
If you have a new growth on your eye and are unsure of its nature, see an eye care professional. Additionally, inform them if your pinguecula appears to be growing and changing, produces symptoms, or impairs your eyesight. Your doctor can look for any changes and suggest the best course of action.
3. What can I expect if I have a pinguecula?
You are likely to have pinguecula for the rest of your life. However, you are unlikely to encounter any problems with it. Eye drops can help relieve inflammation in the eyes. Most pingueculae grow slowly, if at all. In more extreme settings, they may occasionally grow larger. You can have it removed if it begins to cause complications.
