CamBlobs is a simple self-administered contrast sensitivity test for assessment and continued monitoring of retinopathies that result in progressive visual impairment.

Features: The CamBlobs test chart consists of 24 rows of four rectangles on a printed page. Each rectangle contains a gray disc (or “blob”) positioned randomly within it. Blobs become increasingly fainter moving down the page. Patients mark the position of as many of the blobs as they can with an “x.” The test is then scored using a transparent overlay.

“The CamBlobs test provides a simple, easy-to-use and accurate way of measuring contrast sensitivity,” says the inventor of CamBlobs, John Robson of University of Houston College of Optometry. “Contrast sensitivity is well known to be significantly reduced in such diseases as diabetes and macular degeneration but measurement of contrast sensitivity has to date been little used to monitor progression of these diseases. Our preliminary trial of CamBlobs in patients with diabetes has allowed us not only to confirm a substantial loss of contrast sensitivity prior to observable retinopathy but also to show that increasing severity of diabetic retinopathy is accompanied by considerable further reduction in contrast sensitivity. This suggests that precise measurement of contrast sensitivity using CamBlobs might be an easy way to both detect and track the progress of this and other retinal diseases.”

Ed Kopidlansky, president of Precision Vision, notes that traditionally, testing contrast sensitivity has been difficult and time consuming. “The CamBlobs test is intuitive and only takes two to three minutes,” he says. “Scoring takes only a minute. We believe that this is a game-changer in contrast sensitivity testing.”

Availability: An introductory kit includes 20 tests with one recording form (five sets of tests A-D); the full kit includes 120 tests with 12 recording forms (10 sets of tests A-L).

Crystal PM and OptikamPad

Crystal Practice Management Software announced the software integration of Crystal PM and OptikamPad from Optikam Tech to streamline the sharing of patient measurement data.

Features: The seamless software integration, which also supports Spectangle Pro, eliminates manual data entry by leveraging Optikam’s Cloud Subscription while auto-populating a series of OptikamPad fields directly into Crystal’s PM. The fields include all ophthalmic measurements in addition to Panto, Wrap, A Value, B Value, ED Value and the DBL Value.

OptikamPad is a standalone iPad app that assists in every facet of the eyewear dispensing process—frame selection, lens demonstrations and eyewear measurements using one single frontal image. The system facilitates the transition from manual to electronic measurements. OptikamPad’s image detection software instantaneously obtains all measurements after snapshot which avoids time-consuming manual placement of reference points.

Shamir Insight

Shamir Insight is launching a microsite,, an online resource for its newest progressive lens design, Autograph Intelligence.

Features: Shamir launched the microsite with the goal of providing comprehensive product information and resources about its newest progressive lens design. Visitors can easily access educational resources, product information, peer reviews and other materials, all in one place.

The microsite provides an in-depth look into the research Shamir performed to create Autograph Intelligence, and explains the features and technologies that make up the lens. Various resources are available for ongoing education, including product literature, videos, an extensive whitepaper, technical information, and detailed material and treatment availability documents.

“We developed the Shamir Autograph Intelligence microsite with the goal of creating a central place where eyecare professionals can easily access resourceful information surrounding Shamir’s most innovative progressive design,” says Mark Becker, vice president of marketing and strategic partnerships.

Vital Stats: In the coming months, the microsite will be updated with self-learning presentation clips, which will provide eyecare professionals a quick and easy way to view the highlights of the lens.
