Mostly True
The text discusses the relationship between eye color and melanin, stating that blue eyes indicate a lack of melanin, brown eyes have more melanin, blue eyes may trace back to one person, and darker eyes reflect sunlight.
Infact verdict: Mostly True (67/100).
The claims regarding eye color and melanin are largely supported by scientific evidence. Blue eyes result from low melanin levels, and brown eyes have more melanin, which is consistent with genetic studies. The claim that blue eyes can be traced to a single ancestor is verified by Snopes. However, the idea that darker eyes reflect sunlight is not supported by the evidence, which suggests darker eyes absorb more light, reducing glare.

True
Science
People with blue eyes indicate a lack of melanin.
Web evidence confirms that blue eyes have little melanin, causing light scattering that makes them appear blue. This is supported by multiple sources, including All About Vision and Auckland Eye.
