Safety & Precautions
Effective 3 October 2026
Stop if it hurts
If you feel eye strain, headache, nausea, dizziness, blurred or double vision, or any discomfort, stop viewing immediately. Do not push through it. If the symptoms continue after you stop, see a doctor or an eye-care professional.
Why 3D needs its own instructions
Glasses-free 3D works by sending a slightly different image to each of your eyes. Your brain fuses the two into depth. That is a real visual workload, and it is not the same as looking at an ordinary screen. Most people adapt within a minute or two. Some people find it tiring, and a small number cannot perceive stereoscopic depth at all. None of that indicates a fault with the film or the app.
Take breaks
- Rest your eyes for 10–15 minutes after every 30 minutes of 3D viewing.
- Take a break sooner if your eyes feel dry, tired or slow to focus.
- Do not view 3D when you are already tired, unwell, sleep-deprived, or have been drinking alcohol. Discomfort arrives faster and you are less likely to notice it.
- Hold the phone roughly at arm’s length and keep it reasonably steady. Viewing from too close, at a sharp angle, or while the phone is moving makes the 3D effect break up and the strain worse.
Children
Not recommended under 6
Children under six should not view stereoscopic 3D content. Binocular vision is still developing at that age and the long-term effects of regular 3D viewing on it are not established.
- Children aged six and over should be supervised and kept to short sessions with frequent breaks.
- Ask a child directly and regularly whether their eyes feel tired or sore. Children often will not volunteer it.
- Keep the film, tray and packaging away from small children. Small parts are a choking hazard.
If you have an eye condition
Consult an eye-care professional before using EyeFly3D if you have, or suspect you have, any of the following:
- Amblyopia (lazy eye) or strabismus (squint, crossed or misaligned eyes).
- A significant difference in prescription or visual acuity between your two eyes.
- A convergence, accommodation or binocular-vision disorder.
- Any condition affecting depth perception, or recent eye surgery.
People with these conditions may perceive little or no depth, and may be more likely to experience strain or headache.
Photosensitive seizures
Epilepsy warning
A very small proportion of people may experience a seizure when exposed to certain flashing images or light patterns, including those that can appear in video content. This can happen to people with no history of seizures or epilepsy.
Stop using the app immediately and consult a doctor if you or anyone viewing experiences any of: convulsions, eye or muscle twitching, loss of awareness, altered vision, involuntary movement, disorientation, or confusion. Parents should watch for these signs in children, who are more susceptible than adults. Risk may be higher if you have a family history of epilepsy or seizures.
Pay attention to where you are
- Never use EyeFly3D while driving, cycling, or operating any vehicle or machinery.
- Do not walk while viewing. The 3D effect requires you to hold a fairly fixed position relative to the screen, and it draws your attention away from your surroundings more than ordinary screen use does.
- Avoid using it near stairs, roads, water, drops, or anywhere a stumble would matter.
- Make sure you have room around you. People have struck furniture and other people while absorbed in 3D content.
The film and the phone
- Do not use the film if it is cracked, chipped, lifting at an edge, or otherwise damaged. Replace it.
- Clean it only with the supplied microfibre cloth. Solvents, alcohol wipes and abrasive cloths will damage the optical layer.
- Eye tracking uses the front camera continuously and 2D-to-3D conversion uses the Neural Engine heavily. Both warm the phone and consume battery faster than normal playback. If the phone becomes uncomfortably hot, stop and let it cool.
- Do not apply the film to a phone with a cracked screen.
This is not a medical device
EyeFly3D is an entertainment and display product. It is not intended to diagnose, treat, cure or prevent any condition, and it is not a vision test. Nothing in the app or this notice is medical advice. If you have a concern about your eyes or your vision, consult a qualified professional.
