The term “blue ray filter glasses” likely refers to blue light blocking glasses, which are designed to reduce the amount of blue light emitted by digital screens. Blue light is a type of high-energy visible (HEV) light that is emitted by electronic devices like smartphones, computer screens, and LED lights.
There is some evidence to suggest that prolonged exposure to blue light, especially in the evening, may disrupt sleep patterns and potentially contribute to eye strain and digital eye fatigue. Blue light blocking glasses are marketed as a solution to reduce these potential negative effects.
However, the scientific evidence supporting the effectiveness of blue light blocking glasses is mixed. While some studies suggest that they may help alleviate symptoms such as eye strain and improve sleep quality, other research indicates that the benefits may be modest or inconclusive.
It’s important to note that wearing blue light blocking glasses is just one of several strategies that individuals can use to reduce eye strain and improve sleep hygiene when using electronic devices. Other strategies include adjusting screen brightness, using the 20-20-20 rule (taking a 20-second break to look at something 20 feet away every 20 minutes), and limiting screen time before bedtime.
Whether or not blue light blocking glasses are a “scam” depends on individual experiences and expectations. Some people find relief from symptoms like eye strain when using these glasses, while others may not notice a significant difference. It’s always a good idea to consult with an eye care professional if you have concerns about your eye health or if you’re considering using blue light blocking glasses. Additionally, be cautious of exaggerated claims and marketing tactics that may overstate the benefits of such products.
