Arclight is an easy-to-use, pocket-sized ophthalmoscope made for diagnosing eye diseases in the developing world. Priced from as low as £5 per unit when purchased in volume, yet performing as well as traditional devices costing 100 times as much, it will enable health workers in out-reach or screening programs to make instant on-the-spot diagnostic decisions.

Lightweight, portable and solar powered, it is affordable for even the most under-resourced health clinics. Early and thorough eye examinations are vital for detecting diseases like cataract, trachoma, and diabetic retinopathy before they cause blindness. The device can also be used as an otoscope to look into the ears.

We are looking forward to the launch of the long-awaited Mk3 Arclight Low Cost Ophthalmoscope / Otoscope. The new and greatly improved device will have a new pushbutton switch and a better quality bulb, plus a few other improvements. Mr William Williams who designed and created the device has informed me that it will be available on the market via The IAPB Standard List in quarter 1 of 2018 subject to final production. We will announce the launch via this News Letter, and also on the IAPB Standard List.

The new and much improved ARCLIGHT MK3 will be ready to order in Quarter 4 2018

About Arclight

Arclight has been developed with help from The Fred Hollows Foundation. The foundation has a history of supporting pioneering, low-cost technologies that have had a tremendous impact on avoidable blindness: the work of Fred Hollows and others, helped create low-cost intraocular lenses in the 1990s revolutionising sight-restoring surgery.

To date, more than 8,000 scopes have been distributed in low-income countries through our partners.

In 2013, the Foundation’s eye health workers in Africa, Asia and Australia tested the device and reviews were overwhelmingly positive.
