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

OPPORTUNITIES

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
