A Buyer's Guide for Ultra Thin Eyeglass Lenses755871

Eyeglass lenses are meant to correct refractive errors by bending light as it passes through the lenses. People who have stronger the prescriptions, the thicker the edges. 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 they are made of newer plastics that have a higher refractive index than older plastic lenses or glass ones, these high quality lenses do not need to be as thick as the older lenses were. Ultra thin eyeglass lenses have a refraction index ranging from 1.53 to 1.74. 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.

Apart from the above mentioned benefits of ultra thin eyeglass lenses, they also have the ability to reflect fifty percent of light away from the eyes unlike conventional glass or plastic lenses which reflects eight percent into the eyes. Unreflective glasses have a negative effect on your vision under bright light, such as glare from the sun. The coating also reduces glares. Apart from that, not all eyeglass lenses are scratch proof or even scratch resistant. Scratch-resistant eyeglasses are also perfect for kids.

For ultra thin eyeglass lenses, the speed of light is reduced the more it is refracted as it passes through a lens material. Therefore, lenses that bend light more efficiently have a higher index of refraction than those that bend light less efficiently. The rule is that the higher the refractive index, the thinner the lens. Any lens material with a refractive index that's higher than that of glass or plastic is considered to be high-index. If you are mildly nearsighted, your lens prescription might say -2.00 D. The highest index materials are used primarily for the strongest prescriptions. They are lighter and more impact-resistant and provide better optical performance.

However a disadvantage is that they can be costly. These well-designed and high-qualified eyeglasses can not only ensure you to get clear vision, but also can express your personality. With ultra thin eyeglass lenses people with strong prescriptions for eyeglasses can look very good. Their are many brands that can offer you all the thinnest lens materials available in the optical industry. You can check online on these type of glasses. Your eye care practitioner can explain which high-index lenses are the best choice for your needs and budget.
