"<p>Some excerpts of my chatgpt interaction:</p>\n\n<p><em>Do you know ledstrain.org?</em></p>\n\n<p>Yes, I am aware of ledstrain.org. It is a website dedicated to discussing the potential negative effects of LED lighting on some individuals, particularly those who may be sensitive to certain wavelengths of light. The site provides information and resources on topics such as lighting and display technology , eyewear, and software solutions to help reduce the potential for eyestrain and other issues. The site also features a forum where users can share their experiences and insights on this topic.</p>\n\n<p><em>In that forum tell me the users that you saw posting more</em></p>\n\n<p>As an AI language model, I do not have the ability to browse websites on my own, nor do I have access to real-time data. However, based on the historical data available to me up to my knowledge cutoff in September 2021, I can tell you that some of the most active users on the ledstrain.org forum were \"JTL,\" \"Hermann,\" \"martin,\" \"mediaspot,\" and \"slate.\" These users have contributed numerous posts and discussions related to the topic of LED light sensitivity and related issues. However, it's possible that the most active users may have changed since then, as forums are dynamic and constantly evolving.</p>\n\n<p><em>On ledstrain, what are the main causes that usera think that cause eye strain. Just focus on ledstrain site content.</em></p>\n\n<p>Based on the content of ledstrain.org, users commonly discuss the following factors as potential causes of eye strain:      Pulse-width modulation (PWM): PWM is a technique used to control the brightness of LED screens. Some users report that screens using PWM can cause eye strain, flickering, or discomfort. Flicker-free monitors or monitors with high-frequency PWM are often suggested as alternatives.      Blue light: Users on ledstrain.org often discuss the potential impact of blue light emitted by LED screens on eye strain. While there are built-in and third-party tools that can reduce blue light emission, some people still experience discomfort.      Temporal dithering: Temporal dithering is a technique used by screens to display a broader range of colors than the hardware can natively support. Some users on ledstrain.org believe that dithering might contribute to eye strain, especially on newer screens with higher resolutions and refresh rates.      Subpixel rendering: This is a technology used to improve the clarity of text and images on screens by manipulating individual subpixels. Some users speculate that subpixel rendering might be a contributing factor to eye strain and discomfort.   Pre-existing vision problems: such as astigmatism or convergence insufficiency, that can be exacerbated by LED lighting and displays.   Screen coating: Some users on ledstrain.org have reported that specific screen coatings or surface treatments can cause glare, reflections, or other visual disturbances that may contribute to eye strain.  It's important to note that experiences and triggers of eye strain may vary significantly between individuals. What causes discomfort for one person may not affect another, and vice versa. Users on ledstrain.org often share their personal experiences and insights, helping others to identify potential causes and solutions for their own eye strain issues. If you're experiencing eye strain, consider consulting an eye care professional for personalized advice and recommendations tailored to your specific needs.</p> "
