I am glad to answer your question. In recent years, we dye our hair for various colors as the fashion trend for other people, or we have colors in born. Red color is the typical color. We should choose the right eyeglasses or contacts for the red hair in this case. Those who have red color hair usually have blue or green eyes, in this condition, you should choose the green or blue eye contacts to suit your hair. For those who dye their hair into red color, we should know green eyes and red hair is the best combination for your appearance. For the buying, you could find the suitable one at online store, such as alibaba, eBay and other wholesale online stores. May this information will help you. By the way, from my point of view, it is better to wear eyeglasses than contacts. Best wishes.
