Virtual Reality (VR) is a new technology that delivers education, healthcare, and entertainment applications. VR immerses users in lifelike three-dimensional (3D) simulations of natural and imaginative environments.

However, there are concerns regarding the use of VR technology. The unique visual demands of VR have made some people wonder if it might be bad for their eyes. Most problems revolve around the brain and eye health.

VR can disrupt the interaction between your brain and eyes, compelling the brain to alter its visual information processing.

According to ABC News, 70% of people report eye strain, nausea, and discomfort after spending time in virtual environments. The fatigue of eye muscles occurs when users attempt to maintain focus on the captivating images displayed on the VR screen.

Why VR is Harmful for Your Eyes?

Eye strain is a prevalent concern in VR headset users. When immersed in VR, users focus on a pixelated screen very close to their eyes. This is an unnatural way of processing visual stimuli that can lead to fatigue in the eye muscles, commonly known as eye strain. Although usually not a long-term condition, it is a symptom that your brain and eyes require rest from the virtual environment.

Regular breaks while using VR are essential, especially for children with developing visual and perceptual systems. Reducing the duration of VR sessions and adjusting display settings can help alleviate eye strain to some extent.

Although eye strain is typically not a serious concern, if you experience persistent problems, it’s advisable to seek an evaluation by an ophthalmologist. Moderation and good practices can make your VR experience safe and enjoyable.

Potential Effects of VR on Your Eyes

Although VR is a new technology, there is limited evidence pointing to the following potential effects:

  1. Eye Strain and Fatigue
    Head-mounted displays employ technology that has the potential to cause eye strain. The VR (& VR headsets) may cause your eye muscles to fatigue due to rapidly changing views or from focusing for long periods. This depends on how far away or close you hold the device. Symptoms include headaches and burning, itching, and dryness in the eyes.
  2. Dry Eyes
    Dry eyes are another potential cause linked with VR (& VR headsets). When people focus their visual attention on an object for extended periods while using the headset, they can experience temporary dryness in their eyes. This is because the eye must lubricate itself by blinking regularly. People blink less often when they become too focused on something, leading to eye dryness.
  3. Blurred Vision
    According to BMC Ophthalmology, frequent or prolonged use of VR (& VR headsets) can lead to temporary episodes of blurred vision, a common manifestation of computer vision syndrome (digital eye strain). The good news is that this blurriness is typically reversible, and your visual clarity should return once you take a break from the VR experience.
  4. Twitching Eyes
    VR involves rapid light switching, flashing, and movements that force eye muscles to adjust just as fast. Prolonged exposure to such pressure can cause involuntary eye muscle twitches. According to Oculus, the significant manufacturer of VR devices, eye twitching occurs in about 1 in 4,000 people. If you experience persistent twitching after using VR, discontinue use, visit an eye care clinic, and consult with your doctor immediately.

Ways to Protect Your Eyes from VR

Fortunately, there are some ways to protect yourself from VR (& VR headsets) to help prevent eye problems. Some of the tips to minimize the risk are:

  • Increase your blink rate: Frequent blinking maintains eye moisture and guards against the onset of dry eye symptoms.
  • Take regular breaks: Resting your eyes after an extended VR session prevents excessive strain.
  • Use artificial tears: These lubricating eye drops can augment natural tear production, preventing eye dryness.
  • Wear glasses or contact lenses: Using this technology without your corrective eyewear will force your eyes to work harder and increase your risk of developing eye strain.

Are There Any Benefits of VR Technology?

Despite the potential adverse effects on your eyes, virtual reality technology has some unique benefits. In terms of entertainment, it provides a significantly more immersive method for exploration and learning than conventional TV or computer screens. Additionally, this technology is increasingly used in several new industries, such as healthcare, entertainment, real estate, and tourism.

When to Visit Eye Care Clinic?

Visit your eye care provider as soon as possible if you experience any eye problems. Prolonged use of VR can strain your eyes, causing symptoms like eyestrain, headaches, dry eyes, and even blurred vision. If these issues persist or worsen, it’s a clear sign that it’s time to consult an eye care professional.

The Bottom Line

Knowing when to visit an eye care clinic is essential if you frequently indulge in virtual reality (VR) experiences and are concerned about your eye health. Regular eye check-ups are advisable, and discussing your VR usage habits with an optometrist or ophthalmologist can help ensure you’re taking the necessary precautions to protect your eyes while enjoying the world of virtual reality.
