Kodak Lens – New Technology to Reduce Eyestrain


I recently interviewed Ed DeRosa, Vice President of Sales and Marketing for Signet Armorlite, Inc. and we got to talking about Kodak Lens – New Technology to Reduce Eyestrain. I think it is a very interesting product and that I should blog about it. I think it is interesting for several reasons, the first one is personal as I get frequent headaches so I want to try it out myself and secondly, this product was developed by an OD who wanted to help his patients see better. Thirdly, it has to be prescribed by the OD or MD so it is a good opportunity for independent practitioners to offer something, new and unique to patients that can really improve the wearer’s every day life.

Here is the information that Signet Armorlite provided on this New technology to Reduce Eyestrain. Kodak Lenses are now available with Anti-Fatigue Progressive Technology. This new technological enhancement, according to the company, is designed to aid presbyopic patients who experience excessive eyestrain and eye fatigue when performing lengthy near-viewing tasks.  Specifically this technology incorporates base-in prism into the reading area of the progressive lens. Dr. Jeff Krall, who developed the patented concept for relieving eyestrain, explains: “While a patient’s eyes will naturally drift outward when performing lengthy near work, the process of turning the eyes in to maintain fixation can lead to such symptoms as eyestrain and visual fatigue that may result in headaches. But the base-in prism in the reading area can assist the normal binocular function of a patient’s eyes for more comfortable near work for longer periods of time.

Using computerized technology, Dr Krall’s anti-fatigue concept has been integrated into Kodak Progressive lens designs. Anti-Fatigue Progressive technology can be added to KODAK Unique, KODAK Precise and KODAK Concise Progessives and are now available for presbyopic patients seeking relief from symptoms of eyestrain and visual eyestrain during prolonged near work.

The specially designed lenses have been put to the test. The Illinois College of Optometry conducted a study, to investigate whether base-in prism in the near portion of progressive lenses could help alleviate eyestrain in presbyopes. The lenses used in the study were of the same design platform as Signet Armorlite’s commercially available progressives, with the exception of base-in prism incorporated in the near portion. Prism was incorporated into the reading area of one pair of glasses, with the other pair acting as a placebo, during this double-blind study where neither the examiner nor patient was aware of the glasses assignment. The study participants wore each pair of glasses for three weeks. The study found progressive lenses with base-in prism in the near portion to have a statistically significant effect in alleviating eyestrain and eye fatigue.

Literature pieces about this new technology are available through Signet Armorlite Customer Service and inquiries regarding this new technology may be directed to Jeff Krall, OD jeff@kralleyeclinic.com or Vance Thompson, MD thompsov@sanfordhealth.org.

  1. I had suffered, like you, from headaches all my life,but around 8 years ago, was getting them every day. After trying every med the headache neuroligist had in his arsenal, to no avail, he told me the only other alternative was to try Botox, which I gladly did. It didn’t help the first 2 sessions(a session comprises around 30 injections on the forehead, down the temples, and into the neck and trapesis(sp) muscles of the shoulders. One has to wait 3 months in between sessions, but, low and behold, after 10 days or so from the third session, it kicked in, and I have been almost headache free since then (preceeding personal note to shirley concerning her headaches.)
    As far as the new anti-fatigue technology, first off, what is to prevent an eye doc from writing an rx for 1 degree prism base in OU, in near? Wouldn’t that be very similar? Additionally,concerning the double blind studies done through the Illinois College of Optometry, the only other double blind study I have seen of theirs was done for Essilor, when they started their Panamic lens, I was in Tampa for the introduction of the Panamic, and had to listen to French scientist talk about the double blind studies the aforementioned College performed for them, the outcome was the Panamic improved patient’s perception of vision by 20% in every quadrant, the Panamic compared to the Comfort. I think we all know how the Panamic turned out in real life settings.
