![]() ![]() A smarter solution involves progressive lenses where different optical effects are built into the lens allowing for sharp vision at a distance and sharp near vision at the same time. In other words: A pair of glasses that makes the near range near again. Since we can’t stop this process, because it’s simply an ageing process, the question is: What tools do we have to help us live well with it? The simplest solution of the eyeglass lens industry are reading glasses. This is when people often notice that their reading distance or the distance, they need to see sharply, becomes larger. It starts at some point in our thirties and then extends into their forties for many. Unfortunately, there is no known way of stopping this process as of now. And when we don’t have this flexibility anymore, we no longer have the capacity for near accommodation or focusing on short distances. The eye lens loses this flexibility as we age. A very flexible element that we can contract to vary degrees when we look at short distances. To describe it briefly: The eye contains our eye lens. Presbyopia is not an age-related farsightedness but the declining ability of our visual system to focus on object at close distances. This change affects all of us because it’s an age-related change in the eye. Question: What can I do about presbyopia or age-related vision impairment?Īnswer: The simple answer to this question is: There is nothing we can do about it. In other words, eyeglasses with progressive lenses are definitely modern eyeglasses that offer us the greatest possible visual comfort in the online and offline world and should finally lose their stigma of being “glasses for old people.” You can read more about this in the article "Taking a Fresh Look at the Smartphone". As this relates to the design of eyeglass lenses, this means that smartphones are viewed primarily through the lower region of the lens. When we glance briefly at our smartphones, we don't move our heads immediately rather, the eyes move downward, and the head follows only if the gaze is held on the phone for a longer period of time. Colleagues in the lab found scientific evidence in a study that smartphones have changed how vision behaves at close ranges. The ZEISS Vision Science Lab, which conducts user-oriented basic research aimed at improving vision, has been carrying out intensive research on present viewing behavior for many years. It becomes increasingly difficult for the eyes to adapt to the constant changes in viewing distance – and these days, we switch between looking up close to far away and back again much more than we used to. The reason is that the ocular lens already begins to lose its elasticity starting at age 30. Before that, digital lenses can reduce eye strain experienced by many people who spend a lot of time with digital devices and switch frequently between online and offline. Eyeglasses with progressive lenses are not just something for people in their mid-40s or older when their vision starts to deteriorate due to age, which is also known as presbyopia. For example, the early stages of progressive lenses, known as digital lenses, are already becoming relevant starting around the age of 30. "Do I need progressive lenses already?" – That's a question you can ask yourself quite early on. ![]()
