Hello! We also went to Dr Leo Seo Wei, who is a paediatric eye doctor in Singapore. My son was already 8 years old when we noticed he had a lazy eye, so we decided to have it checked. Dr Leo was very reassuring and told us there was nothing to worry about. She gave him a prescription, and since then we’ve been more mindful about taking care of his eyes and limiting his screen time. Hope this helps in any way!
