Quality Lens Manufacturing Makes Quality Contact Lens

Dec 16, 2007
What is the difference between one wholesale optical laboratory and another? The secret is in the quality of their lens manufacturing. A company that really knows optics and glass work can provide your optical business with great products.

Contact lenses aren't all the same. There can be a huge difference in quality between one company's product and another's. What exactly makes a good contact lens? Let's look at the tiny details.

Oxygen Permeability

The eyes need oxygen. This is why eye care providers tell customers that they must only wear their lenses 10 hours a day at most. This is also why contacts have to be thrown away so quickly. Without proper oxygen to the eyes, they become irritated and can develop bacterial infections. In the long run, lack of oxygen can permanently damage the eyes.

The newest thing in contact lens manufacturing is silicon hydro gel. This material offers six times as much oxygen permeability, making them safer and more durable. Silicon hydro gel and other new materials such as senofilcon produce lenses that can be worn almost as many hours as the wearer is awake. They can produce disposable ones that last for up to a month.

Hard To Fit Patients

An experienced fabricator understands how to fit patients with special conditions:

* keratoconus
* astigmatism
* dry eyes
* giant papillary conjunctivitis (GPC)
* post-refractive surgery (such as LASIK)
* presbyopia

An eye care professional should choose a lens manufacturer who acknowledges these conditions in the design of their products, who offers different options, and who will give the time and attention to these cases.

State-Of-The-Art Manufacture

Companies have to stay on the cutting edge of lens cutting equipment as well. A great wholesale optical laboratory has to have the most modern optical lab possible, with the best equipment. With good optical lab equipment like bevel edgers, remote tracers and drilling equipment, a good lab can not only get the job done right, but also more quickly and efficiently.

Some labs now use 5-D tracers to shape their products. These machines offer great advantages over the traditional 3-D tracers, and they are much easier to use effectively. With a 5-D tracer, lab technicians can control every aspect of the contact's fit to ensure perfect accuracy. Your customers will appreciate the perfect fit.

Experience And Innovation

Finally, a good lab is one that has been around. They've seen the trends come and go, and the many years of experience give them an advantage over the others. A great manufacturer is one that has many years of experience, as well as an innovative spirit. New technologies and materials are always being used, and a good lens maker keeps up with the newest developments.

Don't trust your contact lens manufacturing needs to any company that doesn't offer all the latest in industry technology. Finding a good manufacturer who will provide quality lenses will keep you ahead of your competitors, and keep your customers coming to you for their eye care needs. After all, your eyes are one of the most delicate parts of your body.
