Safety Precautions.

Please read these precautions before applying your EyeFly3D screen protector or viewing 3D content. They apply to all EyeFly3D and EyeFly3D Pro products.

1. Viewing 3D comfortably

EyeFly3D creates a glasses-free 3D effect by presenting a slightly different image to each eye. This is how normal depth perception works, but on a screen your eyes focus at one distance while converging at another. Most people adapt within a few minutes. A minority find it tiring, and a small number cannot perceive the 3D effect at all. None of this indicates a fault with the product.

Some people may experience:

• Eye strain, tired eyes, or a dull ache around the eyes
• Blurred or double vision
• Headache
• Nausea, motion sickness, or dizziness
• Disorientation or a feeling of imbalance
• Difficulty focusing on nearby objects after viewing

If you experience any of these symptoms, stop using the 3D feature immediately and rest your eyes. Do not resume until the symptoms have fully passed, and do not drive, cycle, operate machinery, or perform any activity requiring balance or clear vision until you feel completely normal again.

To reduce the risk of discomfort:

• Take a break of at least 10–15 minutes after every 30 minutes of 3D viewing, even if you feel fine.
• Every 20 minutes, look at something around 20 feet (6 metres) away for 20 seconds.
• Hold the device at a comfortable arm’s length, roughly 30–40 cm from your eyes, and square to your face.
• View in a well-lit room. Avoid 3D viewing in complete darkness.
• Keep the screen clean — fingerprints and smudges degrade the effect and make your eyes work harder.
• Stop if you are tired, sleep-deprived, unwell, under emotional stress, or have consumed alcohol.
• Switch to standard 2D viewing at any time if 3D becomes uncomfortable.

2. Children and young viewers

Children’s visual systems are still developing, and children are less likely than adults to report discomfort or to stop viewing when they should.

• Under 6 years — not recommended. France’s national health agency (ANSES) advises that children under six, whose visual system is immature, should not be exposed to stereoscopic 3D technologies. Major 3D device manufacturers apply similar or stricter thresholds.
• Ages 6 to 13 — use in moderation and with adult supervision. Limit sessions, enforce breaks, and stop at any sign of discomfort.
• Any child — consult an optometrist or ophthalmologist before allowing them to view 3D content, and particularly if the child has any known vision condition.

Difficulty seeing the 3D effect can sometimes reveal an undiagnosed binocular vision problem such as a squint (strabismus) or lazy eye (amblyopia). If a child cannot perceive the effect, or reports that it looks wrong or uncomfortable, this is worth mentioning at their next eye examination. EyeFly3D is not a diagnostic device and must not be used as one.

3. Photosensitive seizures

A very small proportion of people may experience a seizure when exposed to flashing lights, rapidly changing images, or certain visual patterns, whether in 2D or 3D. This can occur in people with no previous history of seizures or epilepsy. Current clinical evidence indicates that stereoscopic 3D content does not carry a greater seizure risk than equivalent 2D content, but the general precaution applies to both.

Stop viewing immediately and consult a doctor if you or anyone viewing experiences:

• Altered vision, light-headedness, or dizziness
• Involuntary movements, eye or muscle twitching
• Confusion, disorientation, or loss of awareness of surroundings
• Convulsions or loss of consciousness

Consult a doctor before using the 3D feature if you or anyone in your family has a history of epilepsy or photosensitive seizures.

4. When to take extra care

Consult a medical professional before using the 3D feature if you:

• Have a history of epilepsy, seizures, or stroke
• Have any binocular vision condition, including strabismus, amblyopia, or a significant difference in prescription between your two eyes
• Are prone to motion sickness or vertigo
• Have a heart condition or any other serious medical condition
• Are pregnant, elderly, sleep-deprived, or recovering from illness

If you cannot see the 3D effect clearly, do not strain to force it. Use the product in standard 2D mode and consider an eye examination.

5. Handling and applying the protector

EyeFly3D includes a reinforced tempered glass layer. Handle it as you would any glass product.

• Apply on a clean, flat surface, away from children and pets.
• Handle the protector by its edges. Do not flex, bend, twist, or fold it.
• Do not force the protector into position. If it is misaligned, lift gently and reposition.
• Dispose of the backing film, applicator, and packaging immediately after use — small parts are a choking hazard for young children.
• Wash your hands after handling.

If the protector is chipped or cracked, stop using the device immediately. Broken tempered glass can produce sharp fragments capable of cutting skin or injuring the eye. Remove the damaged protector carefully using adhesive tape to lift it — never with bare fingers — and wrap the pieces securely before disposal. A cracked protector will not protect your screen and the 3D effect will be impaired.

General care:

• Clean with a dry or slightly damp microfibre cloth only.
• Do not use alcohol, solvents, abrasive cleaners, or scouring materials — these will damage the optical layer.
• Do not expose the product to extreme heat, open flame, or prolonged direct sunlight.
• Do not attempt to disassemble, cut, or modify the protector.
• Keep the product and its packaging out of reach of children under 3 years.

6. Awareness of your surroundings

The 3D effect is immersive and reduces your awareness of what is happening around you. Never view 3D content while walking, cycling, driving, crossing a road, using stairs, or in any situation where inattention could cause injury to you or others. Before viewing, make sure you are seated or standing safely, with no fragile objects or other people within arm’s reach.

7. If symptoms persist

Discontinue use and seek medical advice if any discomfort continues after you stop viewing, or if symptoms recur each time you use the 3D feature. Persistent visual discomfort should be assessed by an optometrist or ophthalmologist.
