![]() Note aspheric lenses do not alter the quality of vision, but rather are a cosmetic adjustment. ![]() These lenses do not completely cancel the magnification, but I do notice a change in size. For a long time my eyes have looked very big with one noticeably bigger than the other. My prescription is pretty strong and not the same for both eyes. This is also a recent development in lens technology where the concave of the lens is reduced to minimize the magnified appearance of the eyes. These colors are known as a “residual glare.” The heavier coating is prescribed for those who drive more at night and use the computer a lot. A blue or purple coating has 6 layers and a green coating has 9 layers. So, why do my glasses have a glare…a purple glare? It turns out the color of the light reflection is determined by the quality of the anti-reflective coating. At least, I figured that is why it was called “anti-reflective.” All advertisements and demonstrations show clear lenses. Now, I always understood anti-reflective coating to remove all reflection from the lenses. This coating is installed as layers on both sides of the lens to cancel out the intensity of the light reflected from the inner surface and outer surface. This can cause eye fatigue and blurry vision while viewing a screen or driving at night. It removes the “back-glare” that is caused by light hitting the back of the lens and bouncing into the eyes. The purpose of anti-reflective coating is to remove reflections from the lenses to improve the quality of vision and look of the lenses. Even though I have had this on my previous glasses for the past 10 years, there has been a new development recently that causes this colored glare. My lenses have an anti-reflective coating. So, of course, I did some research and felt the need to share my discovery with the world. ![]() Since I did not order purple-rain-lenses, I slightly panicked thinking the lab might have done something wrong. ![]() Out of all the glasses I have worn over the years, this is the first time my lenses have looked like this. It was only after editing my LookBook images that I saw what they were talking about. Friends noted my glasses had a purple reflection, which I did not notice. The red frames I am wearing now were a gift from my brother and father, who also have a healthy sense of style. Thus, lens technology is my kind of party. ![]()
