Other topics you can find information on include the RSI prevention software Workrave, the buying of computer glasses and the risks of working on a laptop or tablet.


This CANS test can be used to see if your workstation is properly set up and if they are at risk of RSI/CANS. When you asked your faculty's or department’s HSE coordinator to do a computer monitor work station test, he or she would like to receive the results of this test before this appointment.

If a staff member indicates having eye complaints due to display screen work, it is recommended to act as follows:

  • Step 1: Contact the HSE coordinator (occupational health and environmental coordinator of the faculty/service department). The HSE coordinator will first inspect whether the display screen has been installed in a correct, ergonomically sound way; if this is not the case, it is advisable to adjust the workplace.
  • Step 2: If adjustments to the workplace are not possible, or if the complaints continue after the adjustments; the HSE Coordinator of the faculty or service department in question fills in the statement of approval (approval of the payment of costs and indicating OFI number).
  • Step 3: The staff member visit one of the affiliated opticians (see for overview: ).

    beeldschermbrilThe original form Fits! pc monitor glasses is to be presented at the appointment. This guarantees the correct solution against fixed prices. The costs are borne by the faculty/service department in question.

    In all affiliated opticians you can choose from Fits! eyeglass frames, the choice herein is limited. If you choose for a Pearle or Eyewish optician you can also select an eyeglass frame from their benefit collection.

    If in the course of time the pc monitor glasses need to be replaced (for example if your prescription has changed) it is necessary to make a new appointment with the HSE-coördinator. For the correct financial settlement a new form (see also step 2) has to be completed again by the faculty/service department and presented to the optician. It is also important to make sure that the viewing distances are still the same as for the purchase of the previous pc monitor glasses. If these have changed (for example as a result of the purchase of a larger monitor) it is important to measure these new distances and to state this on the new form.

    The trajectory described above ensures an objective assessment of a request for pc monitor glasses. Starting point is a model with monofocal glasses with or without extended reading range, for in more than 90% of the cases this is sufficiently effective. Only staff members who really need monitor glasses are eligible for being provided with such glasses. Following this procedure guarantees the correct solution against fixed prices. The prices Fits! Pc monitor glasses) are only available in Dutch, see annexe 3 of procedure aanschaf beeldschermbril. The costs are borne by the faculty/service department in question.

    Incidentally, it is not obligatory to make use of the opticians mentioned under step 2. A consequence of this is that the models and prices as referred to in this memo, may differ and the optician may not invoice the University of Twente directly. The UT compensate, as a maximum, the prices mentioned in annexe 3 of procedure aanschaf beeldschermbril.

An ever-increasing number of people are using mobile devices such as tablets and laptops. This is particularly practical for people who travel a great deal, who have more than one workplace in the office or work at different sites, or attend many meetings. However, the use of laptops and tablets carries a greater risk of RSI. Below, you can find an overview of information on the correct use of laptops and tablets in order to prevent health complaints as far as possible.


The use of laptops is discouraged because it results in an unfavourable posture that draws the head towards the screen, because of the low position of the screen. This puts strain on the head and neck. In addition, the small size of laptops leads to a more static body posture that is more likely to cause health complaints.

As such, laptops do not meet display screen workspace requirements as defined in the Working Conditions Act. There is, however, an alternative: using a laptop station. This allows the user to adjust the height of the laptop screen quickly and easily to any height desired, facilitating a suitable working posture. In combination with an external keyboard and an external mouse, it is possible to create a fully-fledged workstation (see photo below).


Increasingly often, both employees and students are using tablets in addition to other devices such as laptops or desktops. Tablets are practical devices for paperless meetings, for example. It does, however, also have a number of disadvantages. Tablets are not comfortable or productive to use for a longer period of time, nor for writing substantial amounts of text. Leaning forward over the tablet places additional strain on the neck and shoulders, which can eventually lead to health problems.

To minimize physical health complaints caused by the use of tablets, it is important not to view or use a tablet as a replacement for a desktop or laptop (including laptop station).

However, a tablet can be used effectively for short-term activities, e.g. retrieving and reading information and (meeting-related) documents and making brief notes.

The following tips can help prevent health complaints:

  1. Place the tablet on a table. Never balance it on your lap or hold it in your hand (the tweezer grip);
  2. Buy a tablet holder or cover that can also function as a stand. This provides a better viewing angle and prevents severe craning of the neck;
  3. Do not work on a tablet too intensively or for too long. If you need to do a great deal of typing, use a computer that allows you to create an ergonomic workstation;
  4. Work in different places so that you vary your posture and movements; that way, you prevent strains.


For more information about the use of tablets and laptops, please contact your faculty and/or department’s HSE-coördinator. For questions about your working conditions you can initially contact your manager and the HSE-coördinator of your faculty or department. In addition, as a UT member of staff you have free access to the working conditions consultation (AOS) (the UT's working conditions service). The UT organizes various activities to help you gain a better overview of your lifestyle and improve it where necessary. Check the health and welfare activities on our website.
