Night lenses: reviews of hard contact lenses. Video
Myopia has long ceased to be a sentence. Heavy, old-fashioned glasses are being replaced by lightweight contact lenses. A new word in this technology is night lenses. They are put on during sleep and removed during the day.
Night vs day contact lenses – what’s the difference?
Soft daytime contact lenses are made of silicone. They are only worn during the day. These lenses are changed every day, every month, or quarterly, depending on the model. A new word in ophthalmology is night lenses. They consist of a rigid material that allows air to pass through and have a special relief shape.
These lenses are worn only at night, and return your vision to its former acuity within a few hours.
Getting up in the morning, you take off your lenses and enjoy your new vision all day. That is, for a while, your eyes become healthy again.
Myopia occurs due to deformation of the eyeball: it lengthens, and the focus of vision is impaired. Night lenses have a special structure, due to which they press on the cornea and gradually change its shape overnight. Thus, focus is restored for the whole day. The lenses last for about 20 hours. In order not to lose the returned vision, the lenses must be worn every night.
Sleep for at least 7-8 hours: only during this time, night lenses can qualitatively improve vision. Wear them a couple of hours before bedtime if necessary.
Who are night lenses suitable for?
There are hundreds of positive reviews about rigid lenses on the vision correction forums. It is very convenient! Conventional lenses have problems with swimming, water parks and speed sports. And if a speck gets into the eye, you need to urgently remove and rinse the lens. Nightlife workers also like the new invention: dust and cigarette smoke often settle on ordinary lenses. Small children use night lenses successfully. It is so difficult to keep track of a child, during the day he can remove soft lenses with dirty hands or rub his eyes, but with night lenses there are no such problems, because the baby simply sleeps in them. Also hard lenses are a real boon for those with sensitive eyes. No redness, dryness in the eye and foreign body feeling.
Night lenses shown:
- persons from 7 to 40 years old
- with myopia up to -6 and astigmatism up to -1,5
- professional military, pilots, athletes
- with progressive myopia
However, there are a number of contraindications for wearing rigid lenses. Basically, these are various inflammations of the eyes and eyelids, diseases of the cornea, dry eye syndrome.
Night lenses not only correct myopia, but also prevent its progression
