Sometimes you may experience a dry mouth after having the eye drops, but this will be temporary. Very rarely, the drops can cause a sudden rise in pressure within the eye.
The symptoms of this are:
• pain or severe discomfort in or around your eye
• redness in the white of your eye
• worsening or persistent blurred vision a few hours after being screened, sometimes with rainbow halos around lights, and
• nausea or vomiting.
If you have any of these symptoms after screening, you should be seen immediately by your optometrist, or go to an emergency department (A&E). Do not wait as you may need treatment to reduce the pressure in your eye.
