The eye drops that are used in screening may cause a little stinging for the first few seconds. This then disappears.

After about 15 minutes your sight will be blurred and it will be difficult to focus on objects near to you. This is normal. The blurring lasts two to four hours and this will affect your ability to drive (you should not drive to or from your screening appointment).

Apart from the temporary blurriness discussed above, problems after eye screening are thankfully not common. If you experience a problem with your vision or your general wellbeing after your screening, please let us know (see below). 

Rare problems
Very rarely, the eye drops used for screening can cause a sudden rise in pressure within the eye. This only happens in people who are already at risk of developing this problem at some point in their lives. However, when it happens it needs prompt treatment. The symptoms of sudden pressure rise in the eye are:

  • pain or severe discomfort in your eye
  • redness of the white of your eye
  • constantly blurred sight, sometimes with rainbow coloured haloes around lights.
