🔍 Problem Statement

Administering medication to children poses unique challenges for blind parents, encompassing potential safety risks and emotional stress, underscoring the need for accessible medication management solutions and supportive resources.

Most Common Medication Challenges for the Blind & Visually Impaired(VI)

1. Identifying Medication
2. Understanding Medication Information
3. Using Liquid Medication

We learned that bilnd/VI parents struggle with giving medication to their children, especially with identifying and understanding the medication and adjusting the right dosage of liquid medication. They also expressed the desire to independently manage their child’s medication without relying on assistance. They feel anxious when giving medications to their child because of the risk of giving the wrong/expired medication and exceeding the required liquid dosage.
