Blue eyes are generally safe, but they are associated with a slightly higher risk of certain conditions.
Increased Risk of Ocular Uveal Melanoma
Research indicates that individuals with blue eyes may have a heightened risk of developing ocular uveal melanoma, a rare type of eye cancer. This increased risk is linked to the lower melanin levels found in blue irises compared to other eye colors. [Source: All About Vision, Verywell Health]
- Melanin's Role: Melanin is a pigment that protects the eye from harmful UV radiation. Lower melanin levels in blue eyes may offer less protection.
- Cancer Risk: While the risk is still relatively low, it's important to be aware and undergo regular eye exams.
Decreased Risk of Cataracts
Conversely, studies suggest a lower risk of developing cataracts (clouding of the eye's lens) among individuals with blue eyes. [Source: All About Vision, Verywell Health]
- Cataract Formation: The exact mechanisms behind this correlation remain unclear, but it is a noted association.
Protecting Your Eyes Regardless of Eye Color
Regardless of eye color, it's crucial to protect your eyes from sun damage. This includes wearing sunglasses with UV protection, especially when spending time outdoors.

Conclusion
While blue eyes carry a slightly elevated risk of ocular uveal melanoma, they are not inherently unsafe. Regular eye examinations and appropriate sun protection are vital for maintaining eye health, irrespective of eye color.
