Your optometrist may need to use eye drops during your eye examination. The main types of eye drops used by optometrists during appointments are explained below.
Local anaesthetics allow your optometrist to measure eye pressure or remove a foreign body painlessly by numbing the surface of the eye.
Common local anaesthetic eye drops are:
The drops take about 60 seconds to work and the effect may last for up to 25 minutes. They may sting briefly at first.
In the unlikely event that you experience any unusual symptoms such as pain or soreness in or around your eyes or your vision seems blurred, contact your optometrist or seek medical advice as you might be experiencing an adverse reaction to the drops.
Cyclopentolate 0.5% or 1% eye drops are commonly used by your child’s
optometrist to obtain a more accurate reading of the focusing power of your child’s eyes. This works by relaxing the muscles which control the lens inside their eye. They also make the pupil of their eye larger.
The drops take about 30 minutes to work and the effect may last for up to 24 hours.
Your child should not undertake potentially hazardous activities such as cycling until their vision has returned to normal.
Having large pupils will make your child more sensitive to light, especially if it is sunny. As the eye muscles are relaxed, objects close to them will appear blurred and they may have difficulty reading. Most people should be able to see close objects and words clearly again after one to two hours. Sometimes distant objects might also seem blurred.
In the unlikely event that your child experiences any unusual symptoms, contact your optometrist or seek medical advice. Your child might be experiencing an adverse reaction to the drops.
Unusual symptoms include:
Tropicamide eye drops allow your optometrist to view the inside of your eye more easily by making the pupils wider than normal.
The drops take about 15 to 30 minutes to work and the effect may last for up to six hours. Occasionally the effect may last until the next day.
You should not undertake hazardous activities such as driving, cycling or operating heavy machinery while your vision is affected.
Having large pupils will make you more sensitive to light, especially if it is sunny, and your vision might be slightly blurred.
In the unlikely event that you experience any unusual symptoms such as feeling unwell or having pain and redness in or around your eyes or your vision seems misty (as though you are looking through a veil or a fogged up window), contact your optometrist or seek medical advice as you might be experiencing an adverse reaction to the drops.
