High index lenses are prescription lenses that are made from a material with a higher refractive index than conventional lenses. These lenses are thinner and lighter than regular lenses and are often used to correct higher levels of refractive errors such as myopia, hyperopia, and astigmatism. Hi index lenses are also available in a variety of materials, including polycarbonate, Trivex, and high-index plastic.
One of the main advantages of high index lenses is that they are more visually appealing due to them being thinner and lighter. This is particularly important for people with high prescriptions that generally need thicker prescription lenses, as they may be more likely to feel self-conscious about the appearance of their eye glasses.
Another one of the advantages of high index lenses is that they can help improve vision. High index lenses can bend light more effectively and help reduce distortion and improve visual clarity. This can be especially important for people with high prescriptions, as traditional lenses may cause more distortion and make it more difficult to see clearly.
In addition to these benefits, high index lenses are also more durable and scratch-resistant than traditional lenses. This can be important for people who are active or who work in environments where their glasses frames may be more prone to damage.
Overall, high index lenses offer a number of benefits over traditional eyeglass lenses, including improved appearance, improved vision, and increased durability. They are an excellent choice for people who want to improve the comfort and performance of their prescription glasses.
