What Makes BiColor Special
How BiColor Works

BiColor is a digital lazy eye training app developed to support home-based vision therapy for people with amblyopia (commonly known as lazy eye). This vision training game uses dichoptic training techniques and works in combination with anaglyph glasses, offering an interactive way to stimulate visual development.
BiColor includes structured eye exercises for lazy eye, encouraging the brain to process input from the weaker eye. These exercises promote neuroplasticity and vision improvement by engaging both eyes in different visual tasks, helping to reduce suppression and restore balance.
Whether you’re looking for:
- amblyopia exercises,
- eye therapy exercises,
- or a video game for vision therapy
BiColor offers a science-based, engaging solution for all ages.
Use BiColor daily for just 20–40 minutes to enhance the effectiveness of your lazy eye treatment. The game is ideal for children, teens, and adults — making digital vision therapy more accessible than ever.
What is Amblyopia (Lazy Eye) and Strabismus
Amblyopia, commonly known as lazy eye, is a vision development disorder where one eye is weaker than the other. The brain starts to favor the stronger eye, ignoring signals from the weaker one. It usually develops in childhood but can persist into adulthood without treatment.
Strabismus is a condition where the eyes are misaligned and do not point in the same direction. While amblyopia and strabismus can occur together, the treatment approaches may differ.
Principle of Anaglyph Operation in BiColor
- Image Separation for Each Eye
- The program displays two images or image parts on the screen, each intended for one specific eye
- Images are colored in contrasting colors: red and cyan
Anaglyph Glasses as Filters
- Glasses feature two differently colored lenses: red and cyan
- The red lens blocks red color and allows cyan through, while the cyan lens blocks cyan and allows red through
- Thus, each eye sees only the image part colored in the opposite color
Creating the Separation Effect
- Due to filtering, each eye perceives its unique image
- As a result, the brain processes two different images simultaneously, which trains visual perception and stimulates the “lazy eye”
Purpose in BiColor
- Training the weaker eye (amblyopia), actively engaging it by showing images specifically designed for it
- Improving coordination between both eyes and stimulating binocular vision (strabismus) as the brain learns to perceive two images simultaneously, merging them into a single image
Thus, in the context of BiColor, the anaglyph method serves as an effective tool for training and developing the visual system in amblyopia and strabismus.
Mini-Games Description
BiColor offers three engaging mini-games designed for vision training in amblyopia (lazy eye) and strabismus. The game format increases motivation, especially for children, and supports cognitive development, reaction speed, coordination, and fine motor skills.
“Balloons” Mini-Game
Colored balloons numbered 1 to 10 appear on the screen. The player’s task is to pop the balloons in ascending order. This game improves attention, visual focus, and hand-eye coordination.



“Duck Runner” Mini-Game
Control a duck that runs forward, jumping over obstacles. This mini-game develops reaction time, spatial orientation, and visual-motor coordination — essential skills for correcting amblyopia and strabismus.



“Paint” Mini-Game
Players need to color a picture by carefully repeating the original sample. This activity trains fine motor skills, attention to detail, and color perception, supporting overall vision improvement.
