Night Lenses are also known as Orthokeratology or Ortho-K and are special contact lenses that are worn overnight, which are used to correct myopia without the need for laser eye surgery. Night lenses have also been shown to slow the rate of progression of myopia. They are specially designed to harmlessly, and naturally, re-shape the outer cell layer of your eye. Your eye naturally renews these cells every night into the lens to mould it into the correct shape. This means that when you wake up, you can enjoy all the benefits of perfect vision* throughout the day, without the need for daytime contact lenses or spectacles.
*Reverses after 24 hours. Repeat nightly.
The lenses are only for those with a short-sightedness (myopia) of less than -5.00D.
"Night lenses changed my life”
Night Lenses are the latest innovation that everyone’s talking about! A life changing contact lens worn overnight that gives you freedom from glasses, day lenses & laser surgery. Open your eyes underwater, ditch sports glasses, go onto the beach and into the sea without hassle, watch teenage confidence grow and lives transformed. They also halt myopia progression in children – deteriorating short sight linked to eye disease later on in life.

Spotlight on sports professionals using night lenses
Dr Euan Speirits
A Scottish surgeon with a specialist interest in Orthopaedics, Sports Medicine and Biomechanical Research. In his spare time, racing under the name “Rossi”, he is an Elite 4X and Downhill Mountain Bike Racer (Scottish Mountain Biking ‘Hero of the Year’ 2017 no less!)

I’ve been wearing them for 3-4 years. I was put onto them by Scott Brown, a fellow MTB who is an optician. I was wearing monthly lenses at the time. The problem with MTB and monthlies is they dry out and when mud hits them it compromises them. I was getting tired of how frequently they dried out and how uncomfortable that was. Daily lenses dried out quicker, so they were no better. At work when I operated on people my eyes were getting very dry in theatre. Scott told me about night lenses, which I’d never heard of, which was odd given my profession and also the amount of sports I did. I had entertained the idea of laser eye surgery, but was worried about the cost and permanence of it, so never thought it merited doing. Night lenses sounded like a pretty good resolution without permanence.
It has genuinely revolutionised it. It means I can go for a day of competition with zero distraction of eye dry and have a normal life with no need to consider using contacts or wondering whether they will dry out. Recreationally I do a lot of paddleboarding and don’t have to worry about the option of seeing or falling in and losing my contact lens. They have completely normalised life for me.
I couldn’t recommend them enough. Everyone at some point wearing daytime lenses has had them move in their eye and felt the ‘grate’. The knowledge that you don’t have that in high performance sport is a huge difference. No difference between what you can see and what you interpret. No compromise. Your vision is your own. I’m surprised more people don’t wear them, but that’s mainly because so few people have heard of them yet.

Overall, yes. Any sport where you sweat, you rub your face and your eyes. If you’re a contact lens wearer you risk dislodging the lens and so you think about that. Sports glasses feel sweaty and can steam or smear, so you think about them too. To put a top performance together you need to dot all the ‘I’s and cross all the ‘T’s. It would have been a very different story if I had all that background worry about goggles coming off during the swim or dislodging a lens during a race. All I do now is put one lens in and take one lens out. All done. Nothing in my eyes for the rest of the day and the race. Why wouldn’t you want to control the uncontrollable? So many things are uncontrollable in a race – why not control it?
Sport is a part of life. Night lenses, for me, revolutionised my life as they revolutionised my sport experience.
Perhaps the only way I’d go back if I wasn’t being physically active in my life. But then I’ll always be active. I got them because of the volume of physical activity I did and the ease of having a life without having to deal with the hassles of glasses or contact lenses. I briefly came off them twice. The interesting thing was that I mindful of the wastage of day lenses. Night lenses are 1 set of lenses per year versus throwing away a pair every day. For anyone thinking about night lenses who are more attuned to sustainability and environment, this might also be a positive plus point for night lenses. Less waste.
