Purevision Contact Lenses For Hydrated EyesPurevision contact lenses are the first ever of its kind, made by using a material known as AerGel. It guarantees not only excellent vision, but also more eye comfort to the wearer. These are actually nothing but silicone hydrogel lenses that allow great oxygen transmissibility. Not only does this keep the eyes in great heath, it also ensures that the eyes remain hydrated throughout the day. Therefore, there are quite preferable among those who wear lenses throughout the day, removing them only at night. Purevision contact lenses are slightly tinted in color, with a bluish tinge, so that when you remove them form the lens case, and wear them, the entire process becomes very easy. Just like in the colorful lenses with bright FX effects, even these lenses are pretty convenient to locate, clean and wear. In fact, when it comes to cleaning, these lenses hardly give much trouble. For instance, these lenses are capable of repelling debris, even when you are wearing them. Therefore, besides protecting the eyes, and maintaining sharp visibility, these lenses also ensure that too much matter does not get collected on the lens surface. As a result of this when you get down to cleaning your Purevision contact lenses, there is hardly much cleaning required in the first place. Cleaning process thus becomes easier and less time consuming. Another great thing about these lenses is that, unlike any other lens, these are capable of reducing what is known as "spherical aberration". Spherical aberration is a naturally occurring condition that is capable of causing any object to appear hazy or blurred. This hampers the view, and the viewer is not able to well perceive what he may be looking at. Besides, the well shaped lens edge also ensures that not only the lens fit more comfortably, but also that the vision appears better. The Purevision contact lenses are priced modestly, with the price ranging between about forty dollars to fifty dollars, per box. These lenses are great for daily as well as for the occasional lens wearers, who cannot keep track of when to replace their old lenses with new ones. This is because Purevision lenses are meant to be replaced on monthly basis, so that you never quite forget to dispose of the lens. Also since these lenses are monthly disposable, it does not much hurt if you end up losing a pair of these lenses or if a pair gets torn or damaged. You know that those lenses were not supposed to last more than a month anyway, and so the sense of loss is much less! |
