The Science Behind the Fun

👁️

Promotes Active Scanning

Unlike passively watching cartoons, finding a hidden piggy invites 'active scanning' that keeps young eyes searching and engaged. Vision research into amblyopia highlights why active visual engagement matters.

🎯

Visual Discrimination

We use high-contrast palettes and 'crowded' scenes, so play involves telling objects apart from their background, a skill that vision research links to amblyopia.

👆

Fine Motor Connection

The act of spotting a target and precisely clicking or tapping it builds essential hand-eye coordination pathways, reinforcing the connection between vision and action.

🦓

Gabor Patch Stimuli

Level transitions feature decorative Gabor-patch-style animations inspired by patterns studied in vision research.

Suggested Routine

Daily Time

15-20 minutes per session.

What is Amblyopia?

Amblyopia, also known as lazy eye, is a vision development disorder in which an eye fails to achieve normal visual acuity, even with prescription eyeglasses or contact lenses.

Early Detection

Early detection is key. Look for signs like squinting, shutting one eye, or head tilting. Comprehensive eye exams are recommended at 6 months, 3 years, and before starting school.

Frequently Asked Questions

What is Piggy Peekaboo?

It is a free, browser-based game designed to support vision therapy for children with Amblyopia (lazy eye). It gamifies the 'patching' time.

👶

What age is this suitable for?

Suitable for toddlers (3+) to adults. For young children, we recommend parental guidance to ensure they are scanning actively.

👓

Do I need special glasses?

No, you only need an eyepatch to cover the "good eye". The game works on any standard mobile phone, tablet, laptop, or desktop screen.

⏱️

How long should my child play?

Please follow the schedule your ophthalmologist prescribes. Families often play in short 15-30 minute sessions during prescribed patching time.

🧠

Does it work for adults?

Research on neuroplasticity suggests adults may benefit from consistent visual activity too. Piggy Peekaboo is a supportive practice tool, not a treatment, so ask your eye-care professional what is right for you.

🛡️

Is this a replacement for patching?

No. Piggy Peekaboo is simply a fun way to pass prescribed patching time, so you must still wear the patch exactly as your doctor directs!

📄

Can I share my child's progress with their doctor?

Yes. Piggy Peekaboo can export a visual training report as a PDF — summarizing total practice time, daily trends, success rate, and reaction speed — designed to be printed or shared with your ophthalmologist. It is generated entirely on your device from locally stored data.

🗓️

Is there a structured training program?

Yes. You can follow a guided 4–8 week training plan that automatically adjusts each week — gradually reducing the piggy's size, raising the contrast, and introducing red/blue anaglyph mode — so practice progresses steadily over time.

📈

Can I measure my child's improvement?

Yes, in a playful way. A built-in contrast activity shows piggies at progressively lower contrast so you can note the faintest level your child can still spot over time. It is a fun self-check, not a clinical measurement or diagnosis.

💰

Is it really free?

Yes. Piggy Peekaboo is completely free with no ads.

🩺

Is this medical advice?

No. This is a supportive recreational tool. Always follow the specific medical advice and patching schedule prescribed by your doctor.

About the Project

The Background

The Struggle is Real. We know the tears. We know the battles. Research indicates that adherence to patching therapy can be as low as 50% due to emotional distress and boredom (PEDIG, 2003). Telling a child they must cover their "good eye" for hours every day is heartbreakingly difficult when the alternative is monotonous activities like reading or coloring.

The Science

Active vs. Passive. Piggy Peekaboo is built on the principles of Perceptual Learning. Unlike passively watching TV, our game invites active visual engagement: searching, scanning, and focusing. By engaging the child in a task that requires active scanning, discrimination, and rapid focus, the activity is built around active visual scanning and ideas from neuroplasticity research. Recent studies (2023) suggest that gamified and digital approaches may help with treatment adherence.

Our Vision

Joy Meets Progress. Beyond staying 100% free, we strive to create an engaging environment. We want children to want to practice, gaining confidence through achievement and enjoying their progress in the game.
