Comparative evaluation of myDay® contact lenses handling
This study aims to understand how easy MyDay® contact lenses are to handle, especially for people who have blurred vision due to astigmatism. While these lenses are known to work well, some users have found them a bit tricky to handle. Since ease of handling is important for people to like their lenses, this study will compare two types: MyDay® 1-Day Toric® and MyDay® 1-Day Asphere. They want to see if the design of the lens makes a difference. If you are between 18 and 40 years old and already wear soft contact lenses daily, you might be able to help. You'd visit a clinic twice and try both types of lenses, sharing your experience through questionnaires. This study is funded by CooperVision International Limited (UK) and runs from September to December 2025.
At a glance
What is this study about?
Imagine you have a new pair of shoes that fit really well and are comfortable, but they're surprisingly hard to put on. That's a bit like what sometimes happens with MyDay® contact lenses. They're good at helping people see clearly, especially if they have **astigmatism** (a common eye condition causing slightly blurred vision), but some people find them a bit tricky to handle – meaning they're not always super easy to put in or take out.
This study, called "Comparative evaluation of MyDay® contact lenses handling," wants to get to the bottom of this. Researchers want to compare two specific types of MyDay® daily disposable lenses: MyDay® 1-Day Toric® (which are designed for people with astigmatism) and MyDay® 1-Day Asphere (a different type). They'll look closely at how the design of each lens affects how easy it is for people to handle them.
The main goal is to understand if one lens type is significantly easier to handle than the other. This information is really important because if contact lenses are difficult to handle, people might not want to wear them, even if they correct their vision well. By understanding this, manufacturers can make better lenses that are not only effective but also user-friendly.
Key takeaways
- Study compares how easy two types of MyDay® contact lenses are to use.
- Aims to improve lens design for people with astigmatism.
- Requires two clinic visits to try both lens types.
- Participants must be 18-40 years old and currently wear daily disposable contact lenses.
- Small risk of eye infection, as with all contact lens wear.
- You can stop participating anytime.
Who may be eligible?
To be part of this study, you need to be an adult between 18 and 40 years old. You should already be wearing daily disposable soft contact lenses. If you wear regular spherical contact lenses, you might be considered for the MyDay spherical part of the study. If you wear toric contact lenses (for astigmatism), you might be considered for the MyDay toric part.
Your vision also needs to be within a certain range. For example, your glasses prescription should be no weaker than -6.00 and no stronger than +2.00, and your astigmatism should be between 0.00 and -2.25. Your vision with your best correction should also be quite good.
There are several reasons why you might not be able to join. For instance, if you have any active eye infections, severe dry eyes, or certain eye diseases. Also, if you have had recent changes to certain medications, or if you only have good vision in one eye, you might not be suitable.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 40 years old?
- Do you currently wear daily disposable soft contact lenses?
- Is your glasses prescription within the range of -6.00 to +2.00, and astigmatism between 0.00 and -2.25?
- Do you have reasonably good vision with your current glasses or contact lenses?
- Do you have any active eye infections or severe dry eyes?
- Have you had any recent changes to certain medications that might affect your eyes?
What does participation involve?
If you decide to take part in this study, you will need to go to the Ocular Technology Group - International (OTG-i) clinic in the UK for two appointments. During your first visit, the researchers will fit you with one type of the MyDay® contact lenses – either the spherical or the toric kind. You will wear these lenses and answer some questions about your experience. Your second visit will be similar, but this time you'll be fitted with the *other* type of MyDay® contact lenses (the one you didn't try the first time). Again, you'll wear them and complete some questionnaires. The total duration of the study is from September to December 2025, but your personal participation will involve just these two clinic visits.

Common questions
What is astigmatism?
Astigmatism is a common eye condition where your eye isn't perfectly round, leading to slightly blurred or distorted vision at all distances.
What does 'handling' mean for contact lenses?
Handling means how easy the contact lenses are to put in, take out, and generally manage when you're using them.
How many times do I need to visit the clinic?
You will need to visit the Ocular Technology Group - International (OTG-i) clinic for two separate appointments.
Do I have to pay to take part?
No, you do not have to pay to participate in the study. It is funded by CooperVision International Limited (UK).
When does the study take place?
The study runs from September 2025 to December 2025.
