AmblyoPlay is a vision therapy for individuals with difficulties in the vision system, such as convergence insufficiency, lazy eye, strabismus and many others. Therapy is conducted through playing different games that stimulate the weaker eye, as well as encourage good cooperation of both eyes. These vision system difficulties are very frequent: Lazy eye occurs in up to 5% of all population, while other binocular vision dysfunctions occur in up to 15% of all population. These problems can be treated in several ways with recent comparative studies indicating that vision therapy yields the best results. Vision therapy exercises must be performed regularly and correctly to deliver best results and it has been scientifically proven that the therapies work best between the ages of 4 and 14. Vision therapy is performed on a computer or tablet for 30 minutes daily. Each training session is composed of fun and engaging games with challenging exercises for strengthening eye muscles and eye-brain coordination. Valid and active AmblyoPlay account is required for use of AmblyoPlay. KEY FEATURES: EVERY DAY FOR AT LEAST 30 MINUTES! To be successful, vision therapy needs to be performed daily. Due to time and physical constraints, this can not be done always at eye clinics, so a large majority of the success of the therapy depends on the exercises performed at home. Methods in use right now are often described as boring, repetitive and unstimulating, leading to difficulties motivating young clients and consequently leading to suboptimal results. It is not enough to just do the exercises, one has to be engaged and focused. DON’T DO – PLAY VISION THERAPY! It is essential that we engage users with something they already know and love to do. We don’t want kids to feel like they are doing exercises or training, but rather like they are just playing! AmblyoPlay utilises game mechanics to stimulate client. Games and exercises are rewarding them with virtual and physical rewards If they are performing daily therapies correctly. KNOW HOW THEY ARE DOING! Knowing whether therapies and exercises are yielding results is essential. Although one does have to go to eye care specialist for the full eye examination to be certain of the improvements, AmblyoPlay does offer a rudimentary and basic way of tracking the progress of visual function even when not at the doctors’ office. They are designed in a way that it is not possible to progress to higher levels if the visual function is not improving. To further check for the advances in visual function, automated visual acuity screenings are performed every two weeks. PERSONALIZED PROGRAMME THAT GROWS WITH THE USER! When you enter AmblyoPlay for the first time, you are greeted with questions and quick tests that help us determine what mode of vision therapy is best for the user based on their status and their visual function. Based on this information your child will have personalised vision therapy experience with games and exercises working the user progresses through daily therapies, AmblyoPlay is progressing with them. When their visual function improves, the difficulty increases so that the games and exercises keep being engaging and challenging. Through this evolving vision therapy programme, visual functions are always pushed to their current limits, forcing them to improve even further. TOGETHER WITH THE SPECIALIST! AmblyoPlay as home-based therapy can nicely complement the exercises and therapies at clinics. Users are able to add a doctor to their profile and doctor will be able to see in his portal just general information on whether kids are performing the exercises and whether any improvement is noted. Consensus by both parent and doctor will be required to open this option as to prevent any information being seen to unauthorised individuals.
