We'll walk you through the rest of the process.
Making perfect lenses for glasses is both a science and an art. That's why Crystal Vision lenses are made in partnership with the world leader in eyeglass lenses in our USA-based laboratory.
At Crystal Vision lenses, more than 60 skilled employees are involved in making every pair.
When you ask us to make your lenses, you're getting an entire team of professionals working on your lenses,
not just one person in the back room of an optical store.
Most lenses are ready in 1-4 days-sometimes more if they include specialty lens coatings.
Plastic or glass, you'll receive the best lenses installed in a quality controlled, ISO 9000 lens-making laboratory.
Your lenses pass through over 20 quality control checkpoints before they are finally released.
If any imperfection is noticed at any point, the lenses are scrapped and a new pair is created.order Now
Several people are involved in the making of lenses. If one of them makes a mistake,
a loss in vision correction in the lenses will result. The store you choose to make your lenses must insist on
quality at every level to ensure the best quality product.
Even if you're supplied with the best lens material, a poor installation by a technician will result in lenses
that offer poor vision and waste your money. With Crystal Vision Lenses, you know you're getting the exact lens
you ask for, installed with the very highest skill, attention to detail, and quality control.
The brand of lenses determines the clarity of the plastic.
The lens carver of the plastic determines the precision of the lenses. The plastic maker does the surfacing for stock lenses. The lens laboratory does the carving for surfaced lenses.
Your eye doctor determines the prescription for the lens such that it will work best for your eyes. Optometrists tend to write more accurate prescriptions than ophthalmologists. It's not uncommon for an eye doctor to change a prescription if the first prescription is not taken carefully, while blaming the maker of the eyeglass lenses.
An eyewear store employee measures the pupillary distance. Your eye doctor may not write the pupil distance measurement on your prescription unless you ask, in an effort to prevent you from buying glasses lenses at a different store. This is an illegal practice.
The person who carves the lenses for your frame installs lenses so that the optical centers match the pupillary distance measurement. This could be an eyewear store employee, or lens laboratory.
There are two basic ways of cutting lenses, depending on the prescription. Most prescriptions fall within a standard range, called the stock range. 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 so that the store employees can edge the lenses into the frame.
Most multifocal lenses, and all lenses that fall outside of the stock prescription range, must be customized for each prescription. In these cases, plastic is shipped to lens laboratories where it's carved (surfaced) for each individual prescription.
There are hundreds of lens laboratories around the country, several in each state. A typical lens laboratory will do a minimum of a few hundred lenses a day with a large staff of highly trained and experienced technicians. A few optical stores have small surfacing facilities in each of their stores doing much smaller lens volume.
To surface a lens, the lens laboratory takes the blank and puts it through a series of grinding machines, which grinds the surface the lens and shapes it exactly to the specifications of the prescription. Lens laboratories also provide other services like edging and mounting, which optical stores may or may not.
As with any custom service, the quality of the surfacing and any other services is determined by the experience and the expertise of the laboratory, its personnel, and the equipment it uses. We only use labs that employ a large staff of highly trained technicians, doing a large volume of lenses every day.
At Eyeglasses.com, we do none of our own edging services ourselves; it's all done by our lens laboratories. Most of our orders require stock lenses; all of our custom surfacing work is done by lens laboratories. The laboratories that we use each have many years of experience and make thousands of lenses each week. Each lab that we use inspects each lens several times during the manufacturing process. When we receive the finished product from the lab, we do our own final inspection.
