The eye condition pinguecula causes raised yellow spots on the white part of the eye that is exposed to the sun, according to AllAboutVision.com. It is most commonly found in older adults who have had a lifetime of sun exposure.
Protecting the eyes with sunglasses or brimmed hats when outdoors reduces the risk of developing pingueculae, explains AllAboutVision.com. Treatment for the condition is dependent on severity and whether or not the condition obstructs vision or vision correction with contact lenses. Common symptoms include dryness or irritation, such as inflammation or swelling at the site, which is treated with eye drops. Surgical removal is an option in severe cases.
