Recently, the problem of the use of digital devices and the effects of screen time on the eyes has increased, especially when it comes to computer vision syndrome. This is a condition that affects most people in that they develop eye strain and discomfort after too much use of computers, smartphones and tablets. As a result, blue light blocking glasses have come into the limelight. But are they really helpful in treating the symptoms of computer vision syndrome?
Understanding Computer Vision Syndrome
Computer vision syndrome can be described as a group of eye and vision-related symptoms that arise due to the use of screens. The signs range from eye strain, headaches, blurred vision, dry eyes, to neck and shoulder pains. The main problem is rooted in the tendency to look at digital screens, which emit blue light, a short-wavelength light, which is considered to cause eye discomfort.
The Role of Blue Light Blocking Glasses
Blue light blocking glasses are intended to reduce the amount of blue light that is produced by electronic devices. The idea here is that since the blue light is damaging your eyes, these glasses may help to lessen the symptoms of computer vision syndrome by shielding your eyes from it.
There are a number of papers that reviewed the efficacy of blue light blocking glasses, and the results are inconclusive. While some of the users claim to have experienced a significant reduction in discomfort during extended screen hours, others say the change is not very significant. However, the glasses may help those who are most vulnerable to blue light effects.
Are They a Solution to Computer Vision Syndrome?
However, blue light is not the only cause of computer vision syndrome. Other causes include low illumination, wrong positioning of the screen and lens, and unaddressed refractive errors. Wearing blue light blocking glasses can help, but they are not the final answer. Habits that should be taken to prevent CVS include; One should take regular breaks, adjust the settings of the computer, and should also observe the right posture while working.
Additional Measures to Protect Your Eyes
In addition to using blue light blocking glasses, there are several other ways to reduce the impact of digital screens on your eyes:
- Follow the 20-20-20 rule: Every 20 minutes, spend 20 seconds looking at an object 20 feet away.
- Adjust your screen settings: Dim the screen and enlarge the text to reduce eye fatigue.
- Maintain proper posture: Make sure the screen is at eye height and that you are sitting about an arm’s length away from it.
- Use artificial tears: These can also be useful in preventing dry eyes, a major sign of computer vision syndrome.
Conclusion
Many people experiencing computer vision syndrome symptoms have reported improvement when using blue light blocking glasses, however, it should be noted that these glasses should be used in conjunction with other prevention methods. Correct attitude to screen, correct positioning of the head and shoulders and constant breaks are crucial for the long-term health of the eyes. If you continue to get symptoms, the best thing to do is to see an eye doctor.
