WHY?
• Nobody likes wires
• “Smart” devices with sensors
• Passing on data to a “Smarter” device
• “What you cannot measure, you cannot improve”
• Data-driven Prediction Algorithms: Machine
Learning
HOW?
• Low cost chips, printed circuit boards
• Wifi and/or bluetooth capabilities
• Battery (lithium) powered or low voltage e.g. 5 volt
D.C.
• Re-designed bluetooth stack for low power: BLE
• Special stack for low power wifi: Zigbee

ALGOACCESS
We build products that serve:
• Optician, Optometrists and Ophthalmologists
• Eye-care Consumers
OPTICAL PROFESSIONALSEye Health
OPTICAL PROFESSIONALSEye Health
CHALLENGES
• Machines: lensmeter, fundus, autorefractor,
keratometer
• Fragmented marketplace with many machine brands
• Optometry is an old field with standards
• BUT optometry data format has no existing
standards
• Established BLE profiles like Heart Rate Monitor
profile, Battery profile, Proximity profile
• No such standardized BLE profiles exist in eye-care
OPTICAL PROFESSIONALSEye Health
CHALLENGES
• Changing human behavior is non-trivial
• What’s in it for the Optometry professionals?
• What’s in it for the consumers?
TECH LIMITATIONS
• Fundus images require wifi
• iOS BLE has a 1.5 kbps throughput limitations

region/a/140158
From next year, a trip to your optician could end up
saving your eyesight.
That is, if local start-up Algo Access has anything to
say about it. In December last year, the firm bought
licensing rights to one of the projects under the Agency
OPPORTUNITIES
• Computer vision algorithms and machine learning
on fundus images
• Disease prediction: Diabetic retinopathy, AMD (age-
related macular degeneration), Glaucoma, Non-
invasive coronary artery disease detection
OPPORTUNITIES
• Empowering the consumers to manage their health
• Vision test consumer apps on iOS etc
