Smart Glasses that Treat Lazy Eye in Kids

Poco is a pair of smart glasses that help treat Amblyopia (lazy eye) in children age 4-8. They work by dimming one lens to force the brain to use the weaker eye. There is an app that the parents can use to track usage and schedule treatment times. The app also allows the child to play games that strengthen the eye.

Atropine drops

Can permanently solve the issue but has limited success, is invasive and expensive.

The Problem

Design Goal

Empower kids with Amblyopia through a new treatment option using positive reinforcement strategies

What is Amblyopia (Lazy Eye)?


of kids live

with Amblyopia

noun, Ophthamology       /ˌamblēˈōpēə/

Partial or complete loss of vision in one eye caused by conditions that affect the normal development of vision.

The Patient/Child

Kids feel uncomfortable and embarrassed with current treatments. They need a treatment that will empower them.

The Parents

Parents want to make sure their kid is on track to treat this disability while also making sure they are happy.

The Doctor

The doctor would like a better way to track their patients as they usually only see them once every 3 months.

The Secondary Caretaker

The secondary caretaker like a teacher or nanny must be able to aide the child follow treatment in an easy way.

An Empathetic Alternative to Patching

A Discreet and Innovative Solution 

Unlike patching, these glasses blend in and do not embarrass the child. This is just one of many ways to empower the child and make them feel more comfortable with the treatment and more willing to cooperate with it.

Make Treatment Fun and Effective

Children can play videos games to train their eye! Research shows that playing video games which require a lot of concentration and focus make the eye work harder than daily use of the eyes.

Adaptable to Each Unique Case

The Poco glasses and app treatment is customizable to each individual case. Unlike patching which is a one size fits all solution. Every case is unique and requires an adaptive solution to make the treatment more effective.

Poco App

Empower Kids through Storytelling

Help Poco the Parrot fly up the tree to his nest by completing challenges and games while using the glasses!

Gameify Amblyopia Treatment

Games like Tetris and Pong require a lot of focus and eye tracking which trains the eye much more than daily viewing.

Gain Points and get Rewarded

To encourage kids to use the glasses more, points and rewards are given when games are played and challenges are completed.

Compete with your Friends

Poco creates a community of kids with Amblyopia. They can compete with each other through points and games.

Poco App for Parents

The Poco app can also be used by parents through a separate password protected login. Parents will be able to monitor the glasses and see how their child is using them. They will also be able to reach out to their doctor and other parents in the community.


Treatment options for children with Amblyopia are limited and ineffective, this leads to severe eye damage if not treated before age 8.

Problem Statement



I did extensive research on the subject doing a competitive analysis, examining the stakeholders, interviewing doctors, market opportunity analysis and user journey mapping.


Key Insights

Hard to track progression of treatment

Treatment is not reliable

Doctors do not get enough info


Kids are embarrassed wear patches

10/15 participants chose patching as their treatment

12/15 participants chose not to patch their kids at school.

86% of participants wish there were more options.


I ideated around some general solutions that would solve this problem and chose the one that I saw the most potential in.

System Configurations

I thought through all possible configurations for the electronics while considering ergonomic factor like weight distribution and size.

putting the battery and PCB in the back was more discreet and distributed the weight better

I designed the frames by creating outlines and printing them on a laser cutter to see how they looked in real life.

I designed the hinges by modeling them and printing them using an elastic resin so that I could test the flexibility

poor bend, awkward aesthetic when bent

Test #1

Test #2

better aesthetic, still hard to bend

good directional bend, aesthetic is too industrial

Test #3

Test #4

Screen Shot 2019-11-26 at 20.22.11.png

decent bend movement, weird aesthetic

Test #5

playful aesthetic but too bendy and thin

Test #6

playful aesthetic, good bend, but nowhere for wire to pass

Test #7

Screen Shot 2019-11-26 at 20.22.16.png

rounder edges, directional bend, hole for wire to pass

optimized for frame and bend strength



The arms were designed using a combination of sketching and blue foam modeling to test details like button placement.

most comfortable button placement as it doesn't require you to push against the head

this arm design makes the back look thinner by using a darker shade of color


Feedback and Testing

James, age 5

Emily, age 8






Poco means little in Spanish and also relates to the product while being very easy to pronounce for kids. The logo resembles a smiling face.

Appearance Model


I experimented with many different techniques to make realistic flexible hinges and materials for the appearance model.
