Watching TV in a dark room or space is one of the several ideal ways to reproduce the movie adventure – to keep all your attention to the TV screen and to reduce potential distractions. If you’re watching a scary film then it will be that much more terrifying when you’re in a dark space and you have no idea what could be lurking below the sofa, and when you’re watching a love story with a lover then it might be that much more passionate curling up with a blanket in the dark. But there is a downside to this, and for most of us it can give a small problem if we get worried if maybe watching television in the darkness is going to harm our vision. Parents across the world are often asking their children to switch on the light when they watch the TV, and usually it can feel like it factors of headache. So as a result we have a problem – eyestrain.
The number one way to prevent eyestrain is to lower the illumination on the TV. This will signify the illumination doesn’t change the lighting in the room to the same effect and you are able to enjoy looking at the screen at a normal level of brightness. Simultaneously the lower brightness will mean that your photo receptors are less enthusiastic by unexpected flashes and you won’t have glare in front of your face. Naturally most of us would think that brighter illumination would be much better for seeing in the darkness and therefore cause less eyestrain, but in fact the opposite is right! This will be unlikely to have a major impact on how you view TV in the darkness, but it will make some difference. By lowering the contrast you bring the colours and brightness nearer together and this way you will certainly less need to bother about your vision having to re-adjust.
Our eyes when relaxed have a tendency to look directly into ‘middle distance’. Concentrating on something too near to us then can bring our eyes to have to hard work and over a long interval it will lead them to start to fatigue. Also though having the TV set too far away can be a problem as your eyes need to strain to concentrate on length too and specifically if there’s writing on the screen (though most people’s rooms are not big enough for this to be a problem). In other words to find the optimum viewing distance for your television, try letting your eyes just relax and see where they naturally focus. Now just put your TV wherever that point is and you will not need to work to notice it. Finally, if at all possible remove any eyewear. Even if you have fancy designer Tom Ford glasses, they might well end up causing more eye strain than if you remove them, so as above try and adjust your TV to your focal length and minimise the strain that way.
You’re working with one major source of light and the problem is that source of light is playful and shining. Your eyes can just about cope with this but if you let glare get in the way as well then this offers you much more to focus on and makes it more difficult. At the same time it can get in the way of things you are planning to focus on. So just always make sure that if you’re going for the dark room effect that you prevent getting any sources of light opposite the TV screen for example opens windows. Draw some heavy curtains for instance.
Much better than all this though is just to possess a low level of illumination rather than having absolutely no light at all. To achieve this task set up some little lamps across the room that create a comfortable shine instead of bright glare and put these on instead of the big illumination. It will help to make more constant level of the amount of light but at the same time it will still create a slightly cinema-like sense.
