"The diameter of these lens are 14.2mm which is great for my small eyes. Although the size is small I think the darker brown edges gives the lenses an enlargement of 14.5mm lens. I love the color and design. The color is super close to my natural dark brown eyes and the design it not noticeably pixelated up close or further away. I wore these lens for eight hours plus each time I wore them and didn't feel any discomfort.
