What is visual comfort and why is it important?

Visual comfort refers to the feeling of well-being and absence of discomfort experienced when our eyes are exposed to various visual environments, whether indoors or outdoors. It is crucial because it directly impacts our ability to perform visually demanding tasks without discomfort or eye strain. In our modern world, marked by long hours in front of screens and varied lighting environments, maintaining a high level of visual comfort is essential to preserving our eye health and productivity.

How can visual comfort be improved on a daily basis?

To improve visual comfort, several measures can be adopted:

1. Adequate brightness: Adjust the brightness of your screens to match that of your environment, to reduce eye fatigue.
2. Regular breaks: Apply the 20-20-20 rule; every 20 minutes, look 20 feet away for 20 seconds.
3. Workstation ergonomics: Make sure screen distance and height are appropriate to avoid strain.
4. Blue-light filters: Use blue-light filtered glasses or activate the dedicated modes on your digital devices.
5. Ocular hydration: Use moisturizing drops if you experience dry eyes, especially in air-conditioned or heated environments.

What are the consequences of poor visual comfort?

Inadequate visual comfort can lead to a number of health problems, including :

• Eye fatigue: feeling of heaviness in the eyelids, concentration difficulties.
• Dry eyes: Irritation, redness and burning in the eyes.
• Visual disturbances: blurred vision, difficulty adjusting focus.
• Headaches: Often caused by prolonged tension of eye and forehead muscles.
• Impact on productivity: Reduced efficiency in activities requiring visual concentration.

What role does technology play in visual comfort?

Technology, while a source of visual strain, also offers solutions for improving visual comfort. Modern screens with high refresh rates and blue-light reduction technologies can help reduce eyestrain. What's more, adaptive brightness management software automatically adjusts brightness and contrast according to the lighting environment, contributing to a better visual experience.

What types of light are most harmful to the eyes, and how can we protect ourselves?

Blue light and UV rays are particularly harmful to the eyes. Blue light, emitted by the screens of our devices, can disrupt sleep and tire the eyes. To protect your eyes, we recommend using glasses with blue-light-filtering lenses, and activating night modes on digital devices. As far as UV rays are concerned, wearing sunglasses with UV protection every time you are exposed to the sun is essential for eye health.

How can indoor lighting influence visual comfort?

Indoor lighting must be adapted to the activity in question, to avoid eyestrain. Lighting that's too dim forces the eye to work harder, while lighting that's too bright can create glare. We recommend using bulbs with color temperatures that are comfortable for the eyes (between 2700K and 3000K for warm light), and positioning light sources correctly to avoid reflections on screens.

How does posture influence visual comfort?

Good posture is crucial to visual comfort. Working on a computer with incorrect posture can lead to increased eye strain. It's important that the screen is positioned at a distance of around 50 to 70 centimetres from the eyes and slightly below eye level to minimize the need to raise or lower the head, which could increase the risk of neck pain and eyestrain.

What eye exercises can be performed to improve visual comfort?

Several eye exercises can help maintain and improve visual comfort:

• Focusing: Alternate focus between near and far objects to improve lens flexibility.
• Palming: rub your hands together to warm them up, then place them over your closed eyes to rest them.
• Eye movements: Rotate your eyes to reduce tension in the eye muscles. These exercises should be performed regularly, especially after long periods of work in front of a screen.

How important are regular eye examinations for visual comfort?

Regular eye examinations are essential for the early detection of visual anomalies and deficiencies that could compromise visual comfort. An eye care professional can identify problems such as myopia, hyperopia or astigmatism, which often require the use of corrective lenses or glasses. In addition, adjustments may be recommended for work environment or visual habits to optimize visual comfort. Annual visits to the optometrist are recommended for anyone regularly exposed to intense visual effort.
