These drugs act on receptors in the eye to alter the function of the iris. They make the pupil wider to give your optometrist a better view of the inside of the eye.
The drops typically take 15 to 30 minutes to work and generally last up to six hours, although sometimes until the next day. The drops may cause a temporary loss of focus and may sting for a very brief period after instillation.
It’s important to avoid activities such as driving, cycling or operating heavy machinery while the vision remains blurred due to the drops. Sunglasses may be helpful to reduce sensitivity to light due to the large pupils, especially in sunlight.
If you experience any unusual symptoms arise, contact your Specsavers store or seek medical advice urgently. You may be experiencing an adverse reaction to the tropicamide drops.
Unusual symptoms may include:
- Feeling unwell
- Pain and redness in or around the eyes
- Very misty vision with haloes around lights (like looking through a steamy window).
