There is no clinical evidence to suggest your eyesight will be affected by using DSE. As you have read, the majority of problems are ergonomic, which can be rectified with self-assessment, change to working habits and co-operating with your local representative.
If this has been completed and you cannot use your equipment without undue fatigue then you can arrange an eye test with the express approval in advance by the Head of Budget Centre. Note you must be a University employee.
The appointment can be arranged with your local optometrist, with the cost to be borne by the University in arrears – the process varies locally, so please check beforehand. When booking the appointment, you need to mention DSE and know the distance between your eyes and that of your screen. Most tests include this but it is best to have this information handy.
If you do subsequently need spectacles for your computer screen then the cost of test and spectacles will be borne by the Budget Centre. (Should you arrange a test independently without prior agreement, even if it is specifically related to DSE use, you will be responsible for the cost of the test.) The University will pay for a standard frame and lens when it is identified that prescription glasses are required for intermediate distance. The Budget Centre will contribute a maximum of £50 towards more expensive frames or lenses (bifocal/varifocals).
