Patient-reported visual function
Description

Patient-reported visual function

The aim of this questionnaire is to establish what difficulties you have in your daily life due to impaired sight. So that we can develop our healthcare as well as possible we are keen for you to answer the questions in the questionnaire as honestly as you can. The questionnaire contains questions about your difficulties due to impaired sight in connection with certain everyday tasks. If you use glasses for distance and/or close-up purposes, the questions are about what it is like when you use your best glasses. The questions in this questionnaire apply to your situation during the past 4 weeks. When you answer the questions you must try to think only of the difficulties that your sight may be causing you. We appreciate that it may be difficult to decide just what your sight means to you if you also have other problems such as joint pains or dizziness for example. We would still ask you to try to answer how important you think your sight is in your ability to perform the following tasks. When you are asked to state your difficulties, we have given three response options. We call them very great difficulty, great difficulty and some difficulty. Different people may put things differently. Try to see the three response options as three equal size parts of a scale ranging from the greatest to the least difficulty caused by your sight in performing various activities. An example of how we envisage the scale with the three different response options: Greatest ________________ / ________________ / ________________ least very great difficulty great difficulty some difficulty 1. Do you find that your sight at present in some way causes you difficulty in your everyday life?

The aim of this questionnaire is to establish what difficulties you have in your daily life due to impaired sight. So that we can develop our healthcare as well as possible we are keen for you to answer the questions in the questionnaire as honestly as you can. The questionnaire contains questions about your difficulties due to impaired sight in connection with certain everyday tasks. If you use glasses for distance and/or close-up purposes, the questions are about what it is like when you use your best glasses. The questions in this questionnaire apply to your situation during the past 4 weeks. When you answer the questions you must try to think only of the difficulties that your sight may be causing you. We appreciate that it may be difficult to decide just what your sight means to you if you also have other problems such as joint pains or dizziness for example. We would still ask you to try to answer how important you think your sight is in your ability to perform the following tasks. When you are asked to state your difficulties, we have given three response options. We call them very great difficulty, great difficulty and some difficulty. Different people may put things differently. Try to see the three response options as three equal size parts of a scale ranging from the greatest to the least difficulty caused by your sight in performing various activities. An example of how we envisage the scale with the three different response options: Greatest ________________ / ________________ / ________________ least very great difficulty great difficulty some difficulty 1. Do you find that your sight at present in some way causes you difficulty in your everyday life?
