Transparent plastic optical lenses have been used for years as they are manufactured at a low cost and can be created into any shape and are one of the best sources to focus light. However, scientists are trying to make them even better. The downside of using this inexpensive material is that is still reflects light, much more than glass. This is because the index of refraction of plastic is 1.5 as oppose to the air which is 1.0. This means that the lens still reflects about 8% of the incoming light. Researchers are trying to create a later on top of this plastic that reduces the reflection, not only to improve studies but also every day technologies such as cameras and headlights. In result, they have created a coating that reduces the refraction index to 1.1, offering a near transparent transition to air. This will reduce the effects of light rays in cameras, which we have all fallen victim to when trying to take a picture facing the sun.
