From the Research
Cobblestone degeneration is primarily caused by chronic exposure to ultraviolet (UV) radiation from the sun, which damages the conjunctiva over time. This condition, also known as pinguecula or conjunctival degeneration, develops when the conjunctival tissue thickens and forms small, yellowish bumps on the white part of the eye, giving it a cobblestone appearance. Other contributing factors include environmental irritants such as dust, wind, and air pollution, which can exacerbate the damage to the conjunctival surface. Aging is also a significant factor, as the cumulative effects of UV exposure and environmental irritants increase over time. People who spend considerable time outdoors without eye protection, especially in sunny, dusty, or windy environments, are at higher risk. Certain occupations with high UV exposure like farming, fishing, and construction work increase susceptibility. Dry eye syndrome can worsen the condition by reducing the protective tear film. Management typically involves UV-protective sunglasses, artificial tears for lubrication, and avoiding environmental irritants. While no medication specifically reverses cobblestone degeneration, lubricating eye drops can help manage symptoms and prevent progression, as noted in various studies 1, 2, 3, 4, 5.
Key Factors

Note that the provided evidence does not directly address cobblestone degeneration, but the general principles of eye protection and management of related conditions can be applied, as seen in studies discussing diabetic retinopathy and other eye conditions 1, 2, 3, 4, 5.
