Advantages of Ultra Thin Eyeglass Lenses Versus the Conventional Eyeglasses6809292

Most eyeglass wearers are nearsighted, which requires corrective lenses that are thin in the center but thicker at the edge of the lens. The regular glass or plastic lenses for high amounts of nearsightedness or farsightedness can be quite thick and heavy. That is where ultra thin eyeglass lenses can make a big difference.

Ultra thin eyeglass lenses are quite simply lenses that focus light with greater efficiency. Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges than lenses with the same prescription power that are made of conventional plastic material. Most ultra thin eyeglass lenses are even more of a benefit for farsighted prescriptions, which can make conventional lenses very heavy. Also, because they are thinner, a wider variety of frame styles is opened up to the more nearsighted wearer than was possible in the past.

The coating on these lenses are useful for two different reasons. Unreflective glasses have a negative effect on your vision under low-light situations such as when you are driving at night. By reflecting away the unnecessary light, the wearer is less likely to be blinded by oncoming traffic reducing the possibility of road accidents. Apart from that, not all eyeglass lenses are scratch proof or even scratch resistant. Because they have 10 times greater impact resistance than conventional plastic lenses, they are an ideal choice for safety glasses, children's eyewear, and for anyone whose active lifestyle requires light, thin, safe lenses.

For ultra thin eyeglass lenses, the speed of light is reduced the more it is refracted as it passes through a lens material. Regardless of which product you pick, it is important to have an optometrist check your sight first. The rule is that the higher the refractive index, the thinner the lens. Refractive errors and lens powers required to correct them are measured in units called dioptres. If you are mildly nearsighted, your lens prescription might say -2.00 D. Your eyeglass prescription also determines what kind of high-index material you might want for your lens. If you are farsighted, you need "plus" (+) lenses, which are thicker in the center and thinner at the edge.

Ultra thin eyeglass lenses can also provide the ideal solution to your daily optical needs both in pleasure and business. With the wider variety of styles to suit the buyer's needs, these lenses can be worth the added cost. They are created for any gender, particularly suitable for adult and all of them are made with equally distributed weight to create ultimate comfort. Their are many brands that can offer you all the thinnest lens materials available in the optical industry. Thanks to advances in recent technology, we are now able to bring ultra thin eyeglass lenses to needy. But there are exceptions, so ask your eye doctor or optician for details.
