Degressive Lenses: What Are the Benefits?
Degressive lenses allow you to read or write and see the person you are speaking with. These corrective lenses are reserved for people with presbyopia who often do computer work, crafts and other activities around the house. They offer excellent vision at a distance between 30 cm and 1.20 m. Here are all the advantages of degressive lenses!
Degressive Lenses vs Progressive Lenses
From the age of forty, an inevitable physiological phenomenon affects near vision: presbyopia. It is caused by the decrease in the eye's ability to focus due to aging. To correct it, reading or progressive lenses will most likely be recommended. These are ideal for everyday life because they allow you to see at all distances, near, far and in between.
However, progressive lenses are less well suited to an indoor environment, where you likely spend much of your time. If you work in an office, your eyes navigate several times a day between your computer screen, files, phone, and colleagues. It is, therefore, near vision and intermediate vision that are most often used.
With progressive lenses, to see the screen in front of you correctly, you have to raise your head so that your eyes stay in the intermediate zone, located in the lower part of the lenses. This posture creates tension in the neck and shoulders, which can be very unpleasant. In addition, the aberration zones of progressive lenses limit the width of the field of vision. This is why it is recommended to have a pair of glasses specially designed for the office and the home, equipped with degressive lenses.
Degressive Lenses Provide More Comfort at Work
This type of lens offers a wider field of vision, which allows you to see both intermediate and up-close. Thus, with degressive lenses, you can look at your computer screen by keeping a good posture and a natural head position.
Several versions of these lenses are available to give you precise vision depending on your work environment. For example, if you often look at the computer screen and your files, we will recommend lenses with a broader field of vision. They allow you to see the screen without lifting your head. Our eye care specialists are there to provide you with the lenses best suited to your work environment. Make an appointment so that your exact needs can be assessed through specific questions:
- on the nature of your tasks;
- the distance between your eyes and your screen;
- the layout of your keyboard.
An illustrated chart with different options will also be presented to you to better guide you in your choice. Subsequently, precise measurements will be taken, such as the pupillary distance and the height of the gaze line. Your lenses will be centred to the closest millimetre to have the best possible vision, as well as a good posture. Poorly centred glasses can quickly cause discomfort and headaches. That's why it's essential to entrust your glasses to eye care professionals.
Degressive Lenses are Suitable for Your Activities at Home
Glasses with degressive lenses will also be helpful at home. For example, close-up vision is required to read a cookbook or tablet for cooking. But vision at the middle range level is also used for chopping ingredients. Degressive lenses can also be worn for crafting, reading, or playing a musical instrument.
In the end, to ensure you maintain good posture at work, it is important to adjust your workstation… but don't forget to adjust your glasses! To get glasses specifically designed for your work environment, visit us at your local IRIS store!
