From a certain age onwards, usually between 35 and 45, the ability of the lenses in our eyes to adapt to different distances – or accommodation, as the experts call it – diminishes. This is very often a very gradual process. We start to notice it when we have to hold a newspaper or small print at arm's length to read it. This is a condition known as presbyopia. Many people initially opt for reading spectacles to remedy this problem. Work at a computer also becomes increasingly strenuous. Suddenly, we find it difficult to make out the figures in Excel spreadsheets and have to increase the font size on our computer. The texts on our smartphone become blurred and hard to read. The result: we reach for our reading glasses.
Initially, a pair of reading glasses may seem to be a good solution. But remember: reading glasses are designed for very close distances. To see text and images clearly on your computer, you need to move closer to the screen. By doing this, you inevitably adopt a poor and uncomfortable posture. This can result in tension in your neck and back. Even the most ergonomically correct office chair or the best mouse available won't help here.
The next step may be varifocals which you can wear all day for clear, comfortable vision at near and far. These are a very good choice for most everyday situations, but they are suitable for desk or computer work to a limited extent only. Progressive lenses allow you to see at all distances. The lower section of a progressive lens helps you see objects that are close to you. When working at a screen, you also look through the bottom section of the lens. To do this, you have to lift your head in order to see clearly. Adopting this unnatural posture over long periods of time puts excessive strain on your neck and shoulders.
This is precisely where computer glasses are the perfect answer. Their visual zones are precisely tailored to the movements of your eyes when you are working. They can also be individualized to meet your own personal requirements. These glasses offer a very large field of vision at close and intermediate distances (between 2 and 12 feet). This means you enjoy optimum vision in precisely the range of vision your job requires. Your head and neck remain in a natural, relaxed position the whole day long.
And that is by no means all! There are also different designs to choose from, depending on the visual requirements of your job or your leisure activities.
Computer glasses with the lens type "Book": "Book" has a stronger focus on the reading range with a maximum distance of 3 feet. Compared with reading glasses which are generally designed for a fixed and personal reading distance, "Book" offers a significantly larger field of vision for a more relaxed reading experience.
Computer glasses with the lens type "Desk": With this design, the maximum distance over which the eyeglass wearer has clear vision is set at 6 ½ feet. It therefore provides high-quality, natural vision from reading distance right into the intermediate range. This computer lens is ideal for people who work mainly at a computer or read a lot.
Computer glasses with the lens type "Room": With this lens, the maximum distance is set to 13 feet, providing the wearer with comfortable vision from reading distance to a typical room distance. The "Room" version is designed for people who, for example, work intermittently with customers and at a computer screen. When walking around, they do not notice that they are actually wearing computer glasses.
Your eye care professional will help you decide what type of lens is most suitable to meet your personal needs.
It may sound strange, but computer glasses may well be exactly what you need for your favorite hobby, whether it be reading, watching TV, cooking, surfing and chatting on the Internet or playing a musical instrument. They are ideal for any task which you perform at close range or at near to intermediate distances.
