The QSpex lens fabrication system has disposable molds that have all the lens add-ons already on them.
For years, offices with lens finishing equipment have received their stock and uncut lenses from lens supply houses or optical labs, but a growing number of offices are turning to alternative sources. In-office casting and surfacing equipment are becoming more popular as lens designs, materials, and treatments become more varied and easily manufactured in in-office labs.
CASTING The Q-2100™ Digital Lens System from Optical Dynamics is a digital process using reusable free-form generated molds to create finished high-index lenses from liquid monomer. This system produces aspheric, short corridor and standard progressives, FT-28 bifocals, and aspheric single vision lenses. The prescription is entered into a computer and the system instructs the operator to choose the molds from the mold library as well as directing them during each step of the process. The monomer is dispensed into molds and cured. Optional anti-reflective (AR) treatment and front-side mirror coatings available in six colors can be applied to the lenses during the casting process too.
It takes about 30 minutes to process lenses with anti-scratch coating and 90 minutes for lenses with an AR or mirror treatment.
Q-2100R lenses are available in clear and several photochromics in powers from +4.00D to -6.00D sphere with -0.25D to -2.50D cylinder and +1.00D to +3.00D add.
IN THE MOLD The QSpex® Premium Lens System is also a lens fabrication system but with a difference…its disposable molds have all the lens add-ons already on them. This means that office personnel can produce single vision or advanced digital progressive lenses with a combination of lens treatments including hardcoating, a seven-layer vacuum deposited AR treatment, photochromic, polarization, or any combination of these—all in about 35 minutes.
The Fastgrind 2200 System from Super Systems is a modified in-office surfacing system that produces progressives, multifocals, and single vision lenses.
The operator enters the prescription into the computer and the system prompts what molds to use and automatically orders replacements. Each back mold is supplied with a single use disposable lens spacer. The front mold is attached and the liquid is dispensed.
The QSpex Premium Lens Sys-tem uses a proprietary 1.55 index resin to produce single vision and progressive lenses in powers ranging from -4.25D to +2.00D with cylinder to -2.00D and adds from +1.00D to +3.00D. Listen to QSpex’s Kevin Bly talk more about the system at TotallyOptical.com/podcasts.
ECONOMIC SENSE In-office lens manufacturing is convenient and economical. With the decrease in traditional lens costs, competitive product pricing, and increased revenue, the systems pay for themselves in a relatively short period of time. With increased emphasis on profitability these days, more eyecare professionals are eyeing these systems.
FAST GRINDING The Fastgrind 2200 System from Super Systems Optical is a modified in-office surfacing system that produces progressives, multifocals, and single vision lenses. Lens options include CR-39®, photochromic, and polarized. Operators need no surfacing experience and are trained within hours.
Lens blanks come from the company pre-blocked with a disposable lens resin block. The system uses diamond pads, a smoothing pad, and a polishing pad to generate, fine, and polish the lenses, which takes about 12 minutes with an Rx range from +7.00D to -9.00D, cylinders of up to 3.00D, and adds from +1.00D to +3.00D.
Lens designs include FT-28, FT-35, 7x28, and 8X35 trifocals and blended and round bifocals. Progressives include ADDvantage HD and HD Short, Essilor of America, Inc.’s Varilux® Comfort and Ellipse, Younger Optics’ IMAGE®, among others.
Processing lenses in-office pro-vides ultimate control of the quality, turnaround time, and types of products offered while providing the best in eyecare and eyewear.
