Several optical stores have small surfacing facilities in all of their stores doing much smaller lens volume. Lens laboratories also provide other services like edging and mounting, which optical stores can opt for or not, based on whether they wish to accomplish that work themselves. You can find two basic ways of cutting lenses, based on the prescription. Most prescriptions fall within a standard range, called the stock range (typically the range is +/-8.00 sphere and up to +2.00 cylinder). Single vision lenses that are in the stock range are usually surfaced by the plastic makers in bulk by huge computerized machines. These lenses are then shipped to optical stores in order that the store employees can edge the lenses in to the frame.

A disadvantage of polycarbonate is that it is naturally a soft material causing it to scratch much easier. However, unlike CR-39 basic plastic lenses, a scratch resistant coating is nearly always standard since it is applied once the lenses are made. With higher refractive indexes, you can find often more chromatic aberrations, meaning visual disturbances of light, that may be interpreted as blur by some. Chromatic aberrations are higher in polycarbonate lenses. The abbe value of polycarbonate is 30, the lowest of most lens materials making it the worst lens for optical clarity and integrity. For those reasons Trivex is the better choice in a mid-index lens.

Polycarbonate lenses have a higher index of refraction (1.586) than CR-39 plastic (1.498) and so are therefore thinner in an equal lens prescription. With a higher index , light is bent more efficiently, so that it requires less material to achieve the eyeglass prescription making the lenses much lighter. Another significant benefit of these lenses is that they are impact resistant. It’s important to recognize that impact resistant will not mean shatterproof. They are able to still break, therefore official safety glasses should be worn for eye-hazardous jobs and sports. Additionally, Trivex and polycarbonate naturally block most UV light and do not need the use of a UV coating. They are also lab favorites for use in rimless frames, because polycarbonate lenses could be easily drilled and resist cracking round the drill holes.

Digital progressives are customized for every wearer’s prescription. This customization eliminates more distortion and can help you transition to and from far and near vision much more easily.

An anti-reflective coat can increase the level of light reaching your eyes, which in turn enhances your visual experiences. People who spending some time on computers or spend time driving should consider adding an anti-reflective coat to their lenses. With advances in lens technology, ultra-thin lenses is now able to be used to make eyewear for all those with high prescriptions.
