If you’ve just had contact lenses for the first time, it’s easy to worry that perhaps that not in properly. Here we look at how to know if your contact lenses fit properly.
A popular alternative to wearing glasses is to have contact lenses. These tiny lenses are designed to fit right on your eye, so you don’t need to wear frames on your face. They provide just as good a service as traditional glasses, helping improve vision and eye problems such as astigmatism, and many people prefer them. But it can take a while to get use to having something so close to your eye and can take time knowing exactly how to get the right fit.
When you first go to the optician and declare your desire to have contact lenses, they will measure the curvature of the surface of your eye to determine some key measurements. The instrument used to do this is called a keratometer.
This is because everyone’s eyes are slightly different sizes and shapes, so you can’t just get one size of contact lens that will fit everyone. As well as the keratometer, your optician may use a computer to take more measurements of your eyes, as this helps give a more accurate idea of the curve of the whole of the front surface of your eyes.
When the measurements have been taken, your optician should know the size for contact lens you’ll require and the curve they’ll be. If you’re supplied with lenses that are too flat or too steep to fit the surface of your eye, then they could cause unwanted to the cornea and be very uncomfortable to wear, which you don’t want.
As well as the measurements, another key aspect of determining the fit of your new contact lenses is to consider whether your eyes are dry, or whether they’re prone to being watery or running. This is because the fit of certain contact lenses is influenced by whether your eyes are dry or wet. It doesn’t matter if you’re not entirely sure on this issue, or haven’t noticed any particular difference, as the overall health of the cornea will be examined and measured by the optician.
When all of these examinations, measurements and tests have been completed, and if the optician feels your eyes will take to contact lens wear correctly, then it’s time to actual try them for the first time. The optician will generally put them in for the first time, so you can see what they feel like and how they should fit in.
A biomicroscope may be used to help judge how the lenses fit. For example, if they’re found to move around too much as you blink, you may need a slightly different size. It can take a while for a lens to settle in your eye, so it may take 10 to 15 minutes, or a bit longer, for this to be assessed.
Your optician should provide you with lots of help, advice and tips on handling and caring for your new lenses and on how you can get used to putting them in. Although it can take a bit of time to become adept at putting in your own lenses, many people take to it very easily. To put your lens in properly and ensure you get the right fit:
- Wash and dry your hands, then remove the lens from the packet or storage case.
- Put the lens on your index finger, checking it’s clean and the right way up.
- Stand in front of a mirror and carefully hold your upper eye lid open.
- Use your other hand to open your lower lid.
- Look straight into the mirror, then gently place the lens on your eye.
- Slowly release your eyelids and gently blink.
- If you need to, you can gently tough your eyelid in order to get the lens into a central position.
By following these simple tips, you should always be able to get your lenses fitted properly in your eyes, giving you great vision. If it doesn’t go well, the lenses hurt or your eyes feel uncomfortable, it’s a sign that it’s not in properly. Don’t forget to have regular check-ups at the optician, as these can help sort out any problems you may be having.
