The addition (also abbreviated to ADD) is the difference between your basic values for near vision and your basic values for distance vision. If you are interested in varifocals or work glasses, these are important values to consider when ordering.
You are reading a newspaper and notice that you have to hold it further and further away to be able to see the newspaper articles clearly. At the same time, you adopt a totally unnatural posture that leads to a stiff neck and aching arms over a long period of time.
What should you do if your arms are no longer long enough?
You don't need to worry. The first signs of presbyopia can usually be easily corrected, even if you already wear glasses.
What is addition?
Addition is mainly used for varifocals, work glasses and, of course, reading glasses. The addition is independent of your distance correction and is also determined by your ophthalmologist or optician.
It supports your near vision so that you can comfortably read your newspaper articles again.
Presbyopia: What exactly is it?
The eyes lose strength with increasing age. You can compare it to getting gray hair. A normal sign of ageing.
The technical term for this is presbyopia.
With increasing age, the addition usually becomes larger.
This is because the ability to accommodate decreases.
The pair of eyes can no longer adjust so easily to the change in distance from far to near. The reason for this is that the lens of the eye loses its elasticity in the course of life. In most cases, an addition value is determined during an eye test in the early to mid-40s.
As a result of the loss of elasticity, the closest possible near point shifts further and further into the distance, until at some point it is almost impossible to read without support.
