Oh the joys of buying a new TV. So many options and so many things to consider that by the time we buy one, we have convinced ourselves that it is definitely worth our money. With the ultra-high definition, who can argue? The technology along makes it all worth the additional hundreds of dollars, right? Well actually if it is the technology you want, then most certainly they are worth that much. The television technology today is a result of years of research that costs billions of dollars. However, if you want something more tangible then it becomes a different matter altogether.
4K Resolution
Take a look for example at the new 4K resolution which advertisers and manufacturers promise will give a real life viewing experience. Manufacturers compete for the best spots on shelving and in advertising. Already we see 4K resolution making a buzz. Now before you rush to your nearest store or that buy button, here is a look at what this new technology can offer and how it fits into the capabilities of the human eye. In other words, here is a look at the best TV resolution for the human eye.
Visual Acuity
There is no question that these high resolution TVs have good images. The question is are our eyes capable of perceiving all that this new technology has to offer? To answer this question we need to understand the concept of visual acuity or the clearness of vision. 20/20 vision means that we can see an image, or letter as in the case of a vision text, from 20 feet away. Aside from the distance, the size of the object also matters. Without going into the details, the normal, average eye cannot see more than two pixels that are separated by less than 2 one sixtieth of one degree of an angle. Going back to the TV, most human eyes cannot see more than the Retina Display resolution. There exist exceptions, especially among artists.
Other Factors
Of course there are other things that affect the clarity of vision. This includes depth perception, vision skill, our ability to focus and our ability to sense colors. In other words, our overall visual ability affects the clarity of our vision. Other conditions exist that affect this such as hyperopia, presbyopia, and myopia. These eye conditions can be corrected so before you buy that latest TV that offers the best viewing experience, you might want to have your eyes examined. You may have a TV with the best resolution, but if you have a vision problem you won’t be able to see clearly and enjoy your favorite television show to the fullest.
