Eye fatigue and eye strain have become increasingly common concerns, causing things like headaches and more. One major reason for this is the frequent exposure to artificial blue light, coming from computers, phones, and more. Fortunately, options like lens coatings and blue light eyeglasses offer practical solutions to reduce the risk of strain.

What is Blue Light Exposure?

Blue light, a high-energy, short-wavelength light, is emitted by a wide range of sources – including the sun. While exposure to natural blue light from the sun is necessary and beneficial, overexposure to artificial sources can lead to eye fatigue. This condition manifests through a range of symptoms, including dry eyes, headaches, and difficulty maintaining focus during screen-intensive activities.

Anti-Reflective Coatings

One potential solution to reduce or eliminate eye fatigue is by using specialized lens coatings. Anti-reflective (AR) coatings, for instance, are applied to eyeglass lenses to reduce glare caused by artificial light sources, including screens. By minimizing glare and reflections, AR coatings enhance visual comfort and clarity, which is particularly beneficial during prolonged screen use. They work by allowing more light to pass through the lenses, while reducing unwanted reflections that can strain the eyes.

Blue Light Filters and Glasses

Blue light filters/glasses have gained popularity for their ability to selectively block or absorb a portion of the artificial blue light emitted by digital screens. These coatings are designed to maintain a more balanced spectrum of light entering the eyes, effectively reducing the risk of eye fatigue. By incorporating blue light filters into eyeglass lenses, individuals can better protect their eyes from the potential harm of excessive screen time.

Additional Healthy Habits

While lens coatings provide a valuable defense against eye fatigue, it’s also important to make use of healthy screen habits. The 20-20-20 rule, for example, suggests taking a 20-second break every 20 minutes of screen use and focusing on an object at least 20 feet away. This simple practice can significantly reduce eye strain. Additionally, adjusting screen settings, such as brightness and color temperature, can significantly contribute to visual comfort.

While eye fatigue is an increasingly common issue, lens coatings offer effective strategies to alleviate these discomforts. However, it’s also essential to complement these coatings with healthy screen habits, such as the 20-20-20 rule.
