Product description
- The LEA Symbols Playing Cards turn pediatric vision testing and early vision training into a simple, engaging game. Using the standardized LEA optotypes (commonly circle, square, house, apple), children can match, name, or find symbols—helping clinicians assess visual recognition and support visual attention in a way that feels fun rather than clinical. They’re ideal for pediatric clinics, school screenings, and therapy sessions where cooperation and quick responses matter.
- What they support: Visual recognition, symbol matching/naming, attention, and early visual perception skills
- Kid-friendly format: Game-style cards improve cooperation, especially in shy or anxious children
- Works for non-readers: No letters required—ideal for pre-literate children and multilingual settings
- Clinical uses: Warm-up for acuity testing, screening engagement tool, reinforcement during amblyopia/VT home programs
- How to use: “Show me the house,” match-to-sample with a response card, memory games, sorting tasks, timed rounds
- Progressions: Increase distance, reduce cues, add time limits, or combine with occlusion for monocular practice
- Portable: Easy to carry for clinic rooms and outreach camps
- Care: Keep cards clean and flat; store in the box/sleeve to prevent bending and fading
