Possible scenarios:
1. Display brightness problems: The monitors have different brightness and different stereoscopic effects. Some areas are very strong, others are weak.
2. After wearing the 3D glasses, some colours are filtered out, which is a normal phenomenon.
3. These red and blue 3D glasses are suitable for viewing red and blue 3D resources (computers, ordinary TVs, projectors and other devices), direct viewing of ordinary 3D films cannot produce 3D effects.
4. Nowadays, digital 3D films do not harm the eyes, the vertigo varies from person to person. It can lie down after a short break. It is recommended to remove the glasses and rest for a while after watching.
5. Note: Children under 6 years of age must not use 3D glasses to watch stereoscopic films, and adults should also enjoy more peace when watching 3D films.
