The PKUglass

PKUglass is a discreet, lightweight wearable designed to help children with PKU manage their dietary needs. Focused on comfort and subtlety, it offers a functional, non-invasive solution without drawing attention, making it easier for families to navigate daily challenges.

First, what is Phenylketonuria (PKU)?

Phenylketonuria (PKU) is a rare genetic metabolic disorder in which the body lacks or has a deficiency of phenylalanine hydroxylase (PAH), an enzyme necessary for breaking down phenylalanine (PHE). Phenylalanine is an essential amino acid commonly found in proteins. If left unmanaged, the accumulation of PHE in the body can lead to brain damage and cognitive developmental delays. PKU patients must strictly control their diet, limiting their intake of phenylalanine (also known as PA) and regularly monitoring PHE levels through blood tests to prevent long-term damage.

CHALLENINGS

Ongoing adjustments

As children grow, their dietary needs change, and their PHE levels fluctuate, requiring frequent updates to their diet to ensure proper growth and health.

Maintaining a narrow range of PHE

Balancing phenylalanine levels is critical—too high or too low can result in serious health complications, including brain damage or developmental issues.

Dietary control from an early age

PKU children require a carefully monitored diet starting from birth, which can be difficult for families to manage.

Lifelong testing and adjustments

Blood tests and regular dietary changes are necessary throughout life, which places a continuous burden on caregivers.

SKETCH

When designing PKUglass, I prioritized a discreet and lightweight form factor. Since children with PKU often prefer not to stand out, the glasses maintain a neutral and familiar aesthetic, blending seamlessly into everyday life. At the same time, I focused on integrating all necessary functional components within the structure itself, ensuring a streamlined design without adding bulk. This approach enhances comfort and wearability while maintaining the device’s full capabilities.
