A research study analyzing the eyes of 195,000 people of European and Asian origins got conducted by King’s College London and Erasmus College Medical University, Rotterdam. The research findings got released this month in the journal, “Science Advances.”  This study is being considered one of the largest studies in the sphere of the genetics of human eye color. The findings have highlighted certain aspects that are being considered to be promoting a better understanding of eye diseases like ocular albinism and pigmentary glaucoma which are related to eye pigmentation. The reason why the eyes of people of two diverse regions like Asia and Europe was made a part of the same study is that the eye color of Europeans which range from light blue to dark brown genetically match the eye color of the Asians which are in a variety of shades of brown.

Various other researches have been carried on the relationship between eye color and genetics in the past. This latest research builds upon the findings of those and facilitates a deeper understanding of the most prominent feature of the human face – the eyes. It also helps in predictions related to eye color based on DNA, as informed by Dr. Pirro Hysi, Co-Senior Author of King’s College London, and Dr. Manfred Kayser, Co-Senior Author, Erasmus College Medical University, Rotterdam.

As mentioned in “Science Advances,” the latest research findings stress upon the fact that just like skin and hair, eye color is a human trait that is highly complex genetically and that there is a deep connection between genes, melanin pigmentation, iris structure, and morphology.
