Lower the backlight or brightness on the television set. Do not view the TV in a dark room in which the TV is the only light source. Adjust feature settings such as Auto Motion Plus, 3D, Dynamic Contrast, etc.
Turn down the TV's light output.
Many TVs automatically set their backlights to maximum to show HDR content. Turning the backlight down (or turning down OLED Light on an OLED TV), can impact how the TV displays HDR content. It's possible the image might look odd.
Changing the color temperature is one of the best ways to reduce eye strain. Ideally, you want a warmer hue (less blue light and yellowish tone), especially at night when the ambient light is dimmer. Most users find it easier to focus with warm temperature color mode.
Keep the screen brightness the same or brighter than other bright objects in the room. Set your computer to show black characters on a white background. Use a screen filter that reduces glare to enhance screen contrast and make characters easier to read. Use a 3-sided computer hood if glare continues to be a problem.
[Point 5] Review your display brightness setting
This can greatly reduce the strain on your eyes. For example, in an office with normal brightness of 300-500 lux, the display brightness should be adjusted to around 100-150 cd/m2.
The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
We suggest you turn the sharpness control down to zero, then add sharpness sparingly only if the image looks soft, with poorly defined edges. Also turn off any noise-reduction and image-enhancement or “dynamic” modes; these tend to reduce image quality.
You may find that sitting a bit further than usual from your television, getting a bigger or higher-definition television, or adjusting the display settings may be easier on your eyes. If you tend to experience eye strain or eye fatigue frequently, consider asking your eye healthcare provider for advice.
If you watch TV at night with EyeComfort Mode enabled, the blue light level will be reduced and your images will appear warmer. This can help reduce eye strain but still provide crystal clear images. After sunset, you will see significantly warmer colours and reduced brightness.
“When we look at something close-up, such as a computer screen or a cellphone, the lens of the eye naturally contracts. If you're looking at a screen for prolonged periods, the lens doesn't have the chance to relax, which can lead to eye fatigue,” explains Akpek. This eye fatigue is also due to a decrease in blinking.
Always keep the brightness to be at a moderate level too less or too much of the brightness causes your eyes to strain and is very harmful to eyes.
TVs have long been far brighter than necessary for the average room. HDR does potentially make the problem worse, since they are, on the whole, much brighter than older, 'SDR' TVs. If you experience eye strain with HDR or other material trying these fixes might help you.
Therefore, balancing the Contrast will help keep the eyes from working too hard. Usually, a contrast level between 60-70% is considered the best, but the Contrast will also increase as the Brightness increases.
So, if you're trying to ease your eyestrain, a refresh rate of 120 Hz is optimal. There's no need to pursue those high-end 144 Hz or 240 Hz monitors from Amazon or Best Buy.
Since a 4K Ultra HD TV has more pixels than a 1080p Full HD screen, you can sit closer to get fully immersed without recognizing any pixels. Therefore, the perfect viewing distance for 4K UHD TV screens is roughly 1 to 1.5 times the screen size. 40'': The optimal screen distance lies between 3.5 and 5 feet.
To address chronic eye strain and fatigue, turn on a light. While watching television or a movie on your computer, try turning on a light, preferably one that illuminates from behind the screen.
Generally speaking, you should place your TV around double the distance of the screen size away from your sofa. This sounds a bit confusing but it's quite simple. If you have a 60-inch TV, your sofa should be placed double the distance away - so 120 inches, or about 3 metres.
In some cases, the best sharpness setting is actually zero, while on most TVs the setting is best in the bottom 20% or so. It's understandable if you're confused. After all, an image that's too bright or garish is easy to understand, but sharpness takes some explaining.
Depending on what TV you have, you should set your sharpness to 0% or anything under 50%. If you notice a halo appearing around objects or if the image is too grainy, your sharpness setting might be too high. You will also notice that motion looks more natural when your sharpness settings are correct.
A TV with its sharpness set high may appear sharper, but it will lack the more natural, finer details that you'd see with the sharpness set to low or zero. To properly set sharpness, turn the setting down until you can no longer see false white lines and noise around hard edges.
-Helpful in reducing eye strain. Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect.
Conversely, in a brightly lit environment, a darker screen can actually force your eyes to work harder. If truly concerned about eye strain or dryness, you might be better off investing in artificial tears or a matte screen for your device.
Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast. Sunglasses with yellow lenses can be very effective in filtering out not only UV but blue light too.
