If you have an eye condition called astigmatism, it means that either your cornea or lens has an irregular shape. This irregular shape causes blurred vision because your eyes are not able to focus light rays correctly on the retina. One of the best ways to correct vision problems caused by this condition is to get astigmatism contacts colored. However, colored contact lenses for people who suffer from this condition are pricier than traditional lenses.
The reason why they are more expensive is that they are harder to make when compared with ordinary contact lenses. So how do contact lenses made for people with this condition really work? The lenses are designed with dots, lines and shapes which cover the entire iris, as well as alter its color. Each time you wear the lenses, light will first pass through the lenses prior to touching the cornea. The lens then bends the light in such a way that it hits the central point.
