Quality Lens Manufacturing Makes Quality Contact Lens

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.
