According to this article, researchers have found 50 new genes involving eye color in a study that entailed the genetic analysis of around 195,000 people across Europe and Asia. It is said that this new finding can help scientists understand eye diseases better, such as pigmentary glaucoma and ocular albinism, in which both conditions deal with levels of pigmentation. According to this article, annually, 2,500 people are diagnosed with uveal melanoma. With more and more research coming out, scientists were able to report the first evidence of a strong relationship between genes linked to eye color and the development of uveal melanoma. The research team also discovered that, within Asians, the variation of brown colored-eyes are similar to Europeans who have eye colors ranging from dark brown to light blue.
