Are All Computer Glasses Designed to Block Blue Light?
No, not all computer glasses are designed to block blue light. While many brands offer blue light blocking features, some glasses are intended for different purposes, such as enhancing contrast or reducing glare without specifically filtering blue light.
Computer glasses differ in functionality. Some glasses include coatings that filter out a significant amount of blue light emitted from screens. For example, clear blue light blocking glasses may reduce harmful blue light by 30-50%. Other glasses might focus on anti-reflective coatings to reduce glare, but do not specifically target blue light. Brands like Gunnar and Felix Gray are well-known for their blue light blocking features, while other eyewear brands may not emphasize this aspect.
The benefits of blue light blocking glasses include reduced eye strain and improved sleep quality. According to a study by Hii et al. (2020), individuals who used blue light blocking glasses reported less eye discomfort during prolonged screen time. Furthermore, a survey by the Vision Council found that 70% of people experience some form of digital eye strain, indicating a growing need for solutions like blue light blocking eyewear.
On the downside, some computer glasses may not effectively block blue light as advertised. A study by Akerstedt et al. (2012) suggests that excessive screen time can lead to digital eye strain regardless of the glasses used. Moreover, users may rely too heavily on these glasses without adopting other preventive measures, such as regular breaks from screens.
For those considering computer glasses, it is essential to check for blue light blocking features if that is a key concern. Look for reputable brands that provide clear information about their blue light filtering capabilities. Additionally, practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds to help reduce eye strain. Tailoring eyewear choices to individual needs and screen habits will enhance overall visual comfort.
