If you're wondering whether blue light glasses are worth the money, read this article! You'll learn whether these glasses help prevent digital eye strain and give you headaches. Plus, you'll find out why they don't protect you from the harmful effects of blue light. And if they do work, they're worth the money.
They don't work
While many people tried blue light glasses, they failed to reduce digital eye strain. This modern lifestyle contributes to a high level of digital eye strain and is a leading cause of eye disease. Blue light glasses do not work as well as many people think.
There are several reasons blue-light-blocking glasses do not work. First, they are made with customized lenses to block out the wavelengths at 440 nanometers, where most damage occurs. The blue light portion may be similar between prescription and non-prescription lenses, depending on the manufacturer. So, it is best to purchase glasses with a broad spectrum of blue light filters to ensure you have blue blocker glasses that protect your eyes, if you are worried about the health risks of using your computer all day.
They don't relieve digital eye strain symptoms
Many people use digital devices to relax at the end of a long day. However, too much time spent on screens can result in digital eye strain or computer vision syndrome. People may feel headaches and blurred vision after prolonged computer use, and wearing blue light glasses is a popular solution. To reduce the risks of digital eye strain, try to limit your computer use in the evenings and during the weekends. You may also consider adjusting your environment or night mode settings to prevent eye strain.
By wearing blue light-filtering glasses, you can reduce exposure to blue light. Digital devices produce this light, which is especially damaging to the eyes. However, some studies indicate that other factors, not blue light, cause digital eye strain.
They cause headaches and dry eyes
The symptoms of computer use have been linked with blue light, a type of visible light. Blue light causes headaches and other symptoms like eye strain, blurred vision, and dry eyes. The American Optometric Association has studied the effects of computer use on our eyes. In a study of 69 migraine sufferers, researchers exposed them to varying blue and red light intensities. After a week of exposure to blue light, the participants reported increased headache intensity.
The harmful effects of blue light on migraines and headaches are linked to a higher risk of eye strain, aggravated by long periods of use. Unfortunately, this condition is common when reading a book and using lighted e-readers.
They don't protect against the effects of blue light
While blue light has been linked to a range of health conditions, it is likely not the cause of digital eyestrain. Dry eyes and headaches caused by prolonged exposure to digital screens are more likely culprits, and wearing blue glasses won't help. Researchers are unsure whether this exposure damages our eyes.
The American Academy of Opthalmology does not recommend using blue light glasses and believes the light from digital screens is not harmful. A systematic review in 2017 found no evidence for the benefits of blue light glasses, despite claims to the contrary. However, a small study published in 2019 suggests that blue light glasses can help treat people with Parkinson's disease and sleep disorders.
