The 7 Best Night Lenses for Restoring Adult Vision
Night lenses — a fairly “young” direction in ophthalmologyone. They were certified in Russia for the first time only in 2010. This method of vision correction has become a worthy alternative to medicines, traditional optics and surgical operations to restore visual acuity.
Night lenses for restoring vision are briefly called OK lenses (from the abbreviation of the name of the correction method — orthokeratology). Modern rigid contact lenses are made from gas-permeable materials. They are fixed on the cornea of the eyes in such a way that they make it flatter in 6–8 hours.2. The effect lasts for 2–3 days, which eliminates the need for other means of vision correction.
Despite the originality and novelty of the method, not everyone can wear such lenses. Orthokeratology lenses can be worn by adults and children over 6 years of age.3. They will be most effective under the following conditions:
myopia (up to ‑7 diopters);
farsightedness (up to +4 diopters);
astigmatism (up to ‑1.75 diopters).
The main advantage of night lenses is that they help stop the subsequent deterioration of vision. In addition, this method will help those who are not suitable for surgical correction methods, who cannot wear glasses or soft contact lenses.
Night lenses for restoring vision have practically no contraindications and age restrictions in adults. However, there are conditions in which wearing such lenses is not recommended:
cataract and glaucoma;
dry eye syndrome;
inflammatory eye diseases;
severe visual impairment;
corneal diseases and injuries.
According to doctors, the use of lenses over the age of 45 years is not advisable, since age-related changes in vision proceed quite quickly, which will require frequent replacement of lenses.
Rating of the top 7 best night lenses for restoring vision for adults
The main feature of orthokeratology lenses is night wear2. They are worn for 7–8 hours. One pair of lenses is enough for 1–1.5 years of use. Such a long period of wear and individual production make the lenses quite expensive.
The choice of night lenses is a rather responsible event, so you need to seek advice from an ophthalmologist. In turn, together with our expert — ophthalmologist, associate professor of the Department of Ophthalmology of the Medical Academy named after S. I. Georgievsky Svetlana Chistyakova ranked the most effective night lenses for restoring vision for adults.
1. Paragon CRT 100
Paragon CRT lenses are made from a flexible material patented by the American company of the same name, which allows you to optimally fit the lens to the patient’s eye. Lenses made of this material are a third thinner than their counterparts and have excellent oxygen permeability — about 151 Dk/t. The lenses are suitable for correcting myopia (up to ‑10D) and astigmatism (up to ‑3D). The only drawback of the lenses is the high price

2. MoonLens SkyOptix
Canadian MoonLens lenses combine the use of both tangential and zonal geometry. This allows you to expand the range of vision correction: myopia up to ‑7D, astigmatism up to ‑4D. The material ensures the oxygen permeability of the lenses up to 100 Dk/t, and the duration of the therapeutic effect is 4o 24 hours.
Lenses are available with different color shades, which makes their use more convenient with different visual acuity in the right and left eyes
American Emerald lenses are quite versatile. They have excellent oxygen permeability — 85 Dk / t and safety due to the Oprifocon material. A stable effect of vision correction occurs after 2–3 weeks of wearing lenses. Also, vision correction is possible with myopia in the range up to ‑10D and astigmatism — up to ‑3.0D.
4. Contex Ok-lens
Contex Ok-lens are lenses made in the USA. They help improve vision with myopia up to ‑5D and astigmatism up to ‑1.5D. They are made of Boston XO material and have an oxygen permeability of 100 Dk/t.
Unlike other models, these lenses are more suitable for children and teenagers than others. In addition, after agreement with the doctor, lenses can be worn during the day. This product has a UV filter. It is also allowed to wear lenses 1–1.5 hours before bedtime, which significantly reduces discomfort when falling asleep. Additional features increase the cost of such lenses
These lenses are produced by the Russian company Doctor Lenses, which produces lenses with various combinations of parameters for the correction of myopia, hyperopia, and astigmatism. Lens application range: ‑8.0D to +3.0D, astigmatism up to ‑5.0D. The material used in production is Boston XO with a gas permeability of 100 Dk/t.

6 Zenlens (Sky Optix)
Zenlens are manufactured in the USA by Sky Optix. They also help fight both nearsightedness and farsightedness. The correction range is from ‑6.0 to +4.0D, with astigmatism up to ‑4.0D. The lens material has a gas permeability of up to 200 Dk/t and is designed for 12 months of wear.
In addition to correcting visual acuity, lenses are used after eye surgery, when additional rehabilitation is required. The lens is designed in such a way that it rests on the sclera and does not touch the cornea, providing a tear layer between the eye and the lens. Lenses can be used in children over 10 years old, there is no upper age limit for use
7.Paragon Dual Axis
Paragon Dual Axis lenses are another novelty from Paragon. For its production, an innovative gas-permeable material Paflufkon was used. We drew attention to this model because it was designed specifically for patients with corneal astigmatism. The material from which the lens is made allows you to adjust it according to many parameters, individual for each patient. Lenses have no age restrictions and are suitable for children. The price of lenses is high — about 10,000 a piece.
How to choose night lenses for adult vision restoration
Orthokeratology lenses are selected individually. Each lens must fit exactly to the cornea of the eye. Such selection is carried out by specialized ophthalmological clinics. Before making a lens, the doctor must conduct a series of studies: examining the fundus, measuring intraocular pressure, taking parameters of the cornea and, if necessary, an ultrasound of the eye. It is also necessary to take into account contraindications for wearing lenses, if any.
It is also worth remembering that care products for night lenses are different from care products for soft contact lenses. The storage conditions are also excellent. This must be taken into account when choosing lenses.

Reviews of doctors about night lenses for restoring vision for adults
According to most ophthalmologists, night lenses are most suitable for people who do not have the opportunity to wear lenses or other means of vision correction on a daily basis — for example, athletes or people working in harmful conditions (dust, gas pollution, etc.). They are also suitable for patients who cannot make surgical vision correction (for example, at a young and old age). Such lenses will become an indispensable means of correction after surgical procedures on the eyes or during the rehabilitation period.
The selection of night lenses is a complex undertaking, it requires special equipment and highly qualified doctor. A very important aspect is learning how to put on lenses. The first time lenses should be put on under the supervision of a doctor and see him after the first night of wearing lenses.
