Unlike most polycarbonate lenses, Trivex lenses are internally stress-free. Because of this such lenses have less potential for breaking when under pressure, like from thick frames. This particular characteristic works well with rimless frames or drill mount eyewear. That was all I wanted to say about Trivex vs polycarbonate. Both materials are sufficient for providing…
Trivex also has a slightly lower density so it is lighter than polycarbonate. In fact, Trivex may be the lightest weight lens material available. Another advantage that Trivex has over polycarbonate is that it could be easily tinted. An aspheric lens has flatter peripheral curvatures than a regular spherical lens. Before we get started, we…
As the prescription strength rises, lenses get thicker and heavier. Higher-index material provides thinner and lighter lenses, which makes them an excellent option for anyone who has a strong prescription. Understanding these amounts and how they relate with your eyesight can be an important part of selecting the best lenses for you. With the lens…
Because of dispersion, the index of refraction of a glass varies with wavelength. The most known consequence of this may be the fact that a system could have slightly different focal lengths for different wavelengths of light. For more detailed info on important material specifications such as for example index of refraction and Abbe number,…
For example, the latest Transitions technology or polarized color option will undoubtedly be an option for polycarbonate lens material first. Most updates to high-index lens add-ons roll out half a year to per year later. Most people can’t perceive the colour distortion at these levels. In this situation you want to straight through the lens…
Aspheric lenses may also be much much lighter than standard spherical lenses. This reduces the amount a lens may bulge out of an eyeglass frame, reducing the magnification of the eyes, which improves cosmetic appearance. Your eye doctor can change or replace the lenses in your eyeglasses if needed. You may be able to purchase…
This index is adequate for correcting mild to moderate refractive errors, but is not as effective for the correction of higher refractive errors. Other top features of high-quality titanium frame glasses They’re clear, with shiny surfaces, no scr… Also, high-index lenses with AR coating can give you sharper night vision than uncoated lenses — a…
Lens reflections can also cause glare, further reducing vision in these situations. Generally, lenses with an increased index of refraction will undoubtedly be thinner than lenses with a lower index. The index of refraction of regular plastic lenses is 1.50. The refractive index of high index plastic lenses ranges from 1.53 to 1 1.74. In…
Feel free to get in touch with us in case you have more questions on which type of lens you need to get. The point that the lenses are decentered 7mm each and rectangular shape means the outer edges of the lenses will be very thick. It is smart to choose the lens index in…
If your prescription is lower than +/-6.00 sphere, there is no need so that you can spend the extra money for an ultra high index lens. Conventional glass or plastic lenses reflect about 8% of light that otherwise would reach the attention. High-index lenses can reflect around 50% more light than regular glass or plastic…
