The Device that Revolutionized the Optical Industry

From The Optical Heritage Museum

The AO Lensometer provided a quick and accurate means to verify the power of an eyeglass lens and due to the affordability and ability to mass produce, revolutionized the Ophthalmic lens industry. AO’s chief scientists Dr. Edgar Tillyer and Dr. Estelle Glancy were intimately involved in the engineering effort of this device, which took over 10 years to perfect. Due to this impact on the optical industry, the ASME History & Heritage Committee deemed the AO Lensometer worthy of receiving landmark status.

IOT introduces new Neochromes Agile Dark lenses: extra dark lenses that fade-back fast!

IOT invites patients everywhere—and the ophthalmic industry—to embrace the light with Neochromes Agile Dark, the newest addition to the Neochromes family of light activated lenses. Neochromes Agile Dark lenses are even darker than IOT’s current Neochromes yet fade back just as quickly.

Peace of Mind from Lens Crazing

I’ll never forget the day. The patient was a -9D myope, picking up her glasses in a very expensive frame. As with many myopes, she just wanted a ‘slight adjustment’ – several times. I admit to being a coward when I didn’t try to pop the lenses out to bring the temples in closer. I had wrapped the frame front in a towel, but you know what happened next – the AR on the lenses crazed, resulting in an upset patient as well as the optical manager. Now there’s a way to find the courage for these delicate adjustments.

Double Duty for a Contact Lens

We know that contact lenses can deliver drugs directly to the eye surface, such as Johnson & Johnson’s Acuvue Theravision with Ketotifen. And we know that Sensimed’s Triggerfish contact lens monitors changes in intraocular pressure (IOP) for glaucoma. Now researchers have developed a contact lens that does both. The wireless theranostic contact lens (WTCL) not only tracks IOP, but delivers anti-glaucoma drugs on demand, as reported in Nature Communications. (Toshniwal Paharia, Pooja Toshniwal Paharia. "Glaucoma treatment using smart contact lenses that release drugs". News-Medical. 20 June 2022. https://www.news-medical.net/news/20220519/Glaucoma-treatment-using-smart-contact-lenses-that-release-drugs.aspx.) Note: Theranostics is a combination of the terms therapeutics and diagnostics.
