Smart Contact Lens - Overview
• Smart Contact Lenses are lenses which help in monitoring blood sugar levels in people with
diabetes or look for signs of glaucoma and other diseases. The lenses could also map images directly
onto the field of view, creating head-up displays for the ultimate augmented reality experience,
without wearing glasses or a headset. To produce such lenses, researchers are merging transparent,
eye-friendly materials with microelectronics
• Evolution of contact lenses started in 1508 when Leonardo da Vinci conceptualized the first contact
lens
• Then in 1827 a British astronomer proposed the idea of making a mold of a human eye that could
fit the curvature of the eye
• In 1936, William Fienbloom developed a hybrid contact lens using glass and plastic materials
• In 1959, first hydrophilic water absorbing hydrogel soft contact lenses were made. In 1971 first soft
contact lens was approved by FDA in United States
• In 2008, as a proof of concept, Babak Parviz at the University of Washington in Seattle created a
prototype contact lens containing a single red LED. Using the same technology, he has now created a
lens capable of monitoring glucose levels in people with diabetes. Parviz's design calls for the contact
lens to send this information wirelessly to a portable device worn by diabetic patients, allowing them
to manage their diet and medication more accurately
• In 2014 Google announced a smart Contact Lens that can continuously monitor glucose levels in
tears
• The application domains of these so-called ’smart’ contact lenses have up till now been mainly
limited to biomedical sensing and augmented reality

Search methodology and steps followed to accumulate patent data
Using PatSeer, we searched individual publications and then collapsed them to one member per Family
(Simple Families). Patent families is a group of one or more patent applications in multiple countries
which represent the same invention.
The publications included in the report are updated as of 30th June 2016.
(TACD:((smart) wd2 (contact or intraocular or disposable or bionic) wd2 lens*)
OR
TAC:((camera or sensor or sensing or actuat?r or antenna*) w5 (contact lens*)))
1. We started with a set of 322 records (unique families). After manual review of the complete data set, we
came across some irrelevant records which were removed
2. We flagged/rated each individual record using Search Recall™ option present in PatSeer
3. We then filtered, analyzed and came across some unwanted records
4. After analyzing those unwanted records we restricted our search to filings post 2000
5. After all the above steps we came to an accurate data set of 97 families, which were considered for all the
analysis covered in this report
6. These results were moved to PatSeer project for further analysis
This report analyzes research trends of smart contact lens with a focus on
components, sensors and materials involved and also highlights the key
companies involved in this space.

4.
The search results were added to a Project (in PatSeer) and classified around following five
different areas

Verily Life Sciences – Brief Background
• A branch of Google (now Alphabet Inc) - “Google Life Sciences,” changed name recently
to Verily Life Sciences
• Verily is focused on using technology to better understand health, as well as
prevent, detect, and manage disease. Some of the projects undertaken by Verily include smart
contact lenses equipped with a glucose sensor to better treat and monitor diabetes, a cardiac
and activity sensor, and Liftware utensils for people with tremors
• Verily already has several projects in the works, including the development of a smart contact
lens in partnership with the Swiss drug maker Novartis that has an embedded glucose sensing
contact lens
• Novartis announced that its eye care division Alcon has entered into an agreement with Verily
Life Science to in-license its "smart lens" technology for all ocular medical uses
• Verily is developing the smart contact lenses with a vision that people with diabetes can easily
monitor themselves by continuously monitoring the glucose levels in there tears
