NIGHT LENSES are contact lenses that you pop in at bedtime, your sight is corrected naturally while you sleep, wake to perfect 20/20 vision, remove, have a normal day without needing daytime lenses, glasses or laser surgery. The effect lasts for 24 hours, repeat every night. And yes, they can also stabilise myopia (short sightedness) in children, which is linked to long term eye disease. It’s the ‘sounds too good to be true’ innovation that everyone is talking about.
