Night Lenses For Short-Sightedness – How Do They Work?

Short-sightedness, also known as myopia, is now a global epidemic. Being short-sighted is what we call a refractive error and means you can’t focus on objects that are far away, resulting in blurry distance vision.

For people who are short-sighted, glasses or contact lenses are typically prescribed to correct their vision. However, we now have the opportunity to not only correct myopia, but also slow down it’s progression.

Being highly myopic himself, our principal optometrist Mr Kasmani is passionate about investing in the most effective myopia management methods – something which wasn’t available when he first became short sighted as a child.

One of the most effective forms of myopia control currently available is Ortho K lenses.

Before we look at how they work, let’s take a closer look at how myopia can affect your eyesight and eye health.

About Myopia

It was estimated that around 23% of people around the world were myopic in the year 2000, and that figure is expected to rise to 50% by 2050. Children are more likely to be short-sighted if one or both parents are, and increased screen time has also been highlighted as a potential factor for speeding up the rate of myopia progression.

Developing myopia at a young age can mean your vision can deteriorate even more as you grow, resulting in a stronger prescription, i.e., high myopia. High myopia increases the risk of developing other serious eye problems later on in life, such as glaucoma, cataracts and retinal detachment.



Orthokeratology, commonly known as Night lenses, refers to hard contact lenses that are worn overnight while you sleep to gently reshape the cornea and correct your vision.

When you wake up and remove your Night lenses, you’ll be able to see for the rest of the day without having to wear glasses or regular contact lenses. You’ll notice your vision becoming completely clear within a couple of days of first wearing Night lenses.

These revolutionary lenses are generally considered suitable for anyone who is short-sighted with a prescription of up to -5.00 and can be worn by children as young as 8 years old. They do need to be worn every night in order to keep your vision corrected during the day.

Why Choose Night Lenses?

Mr Kasmani has over 8 years of experience in fitting Night lenses for both adults and children, allowing him to see first-hand how they have positively impacted his patients’ vision and overall quality of life.

We find that most children get used to wearing and caring for their lenses very quickly. A big advantage is that they are only inserted and removed at home under the supervision of parents, making them incredibly safe to use.

We have also seen how much more freedom they give to both children and adults too, allowing them to play sports, go on holiday and splash around in the pool or sea, and experience less overall irritation that can be associated with wearing regular contact lenses, like dry eyes.

Why Choose Night Lenses?

Perhaps one of the biggest benefits is that Ortho K lenses are clinically proven to slow down the progression of myopia, giving kids a better chance of protecting their vision and eye health as they get older.

Night lenses are also a safe alternative to laser eye surgery for adults as there is less risk involved. This is because the effects are temporary, meaning if you do want to revert to using glasses or regular contact lenses, you can do. All you have to do is stop wearing them, and your prescription will go back to what it originally was within a few days.
