The 7 Best Night Lenses for Restoring Adult Vision

Is it pos­si­ble to stop wear­ing glass­es or every­day con­tact lens­es with­out vision cor­rec­tion surgery? Today there is such an oppor­tu­ni­ty. Rigid night lens­es for restor­ing vision — a great alter­na­tive to oth­er cor­rec­tion meth­ods
The 7 Best Night Lenses for Restoring Adult Vision
The 7 Best Night Lens­es for Restor­ing Vision for Adults

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;
    immunodeficiency states;
    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.

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.

Popular questions and answers

Oph­thal­mol­o­gist Svet­lana Chistyako­va answers the most pop­u­lar ques­tions regard­ing the wear­ing of night lens­es.

How do night lenses work to restore vision for adults?

— The night lens con­sists of two lay­ers. The first lay­er cor­rects vision like an ordi­nary lens, the sec­ond one has a denser struc­ture and changes the cur­va­ture of the cornea of ​​the eye in a few hours of wear­ing. This effect per­sists through­out the day and allows you not to use glass­es or oth­er lens­es dur­ing the day.

How long does the effect of night lenses last?

— The dura­tion of the cor­rec­tive effect depends on the type of lens. After 6–8 hours of wear­ing, visu­al acu­ity is restored for a peri­od of 24 to 72 hours. The cor­rec­tion has a “cumu­la­tive effect”, so over time, the lens­es can be used less fre­quent­ly.

How to put on night lenses?

- Night lens­es can be put on as usu­al, using fin­gers or spe­cial suc­tion cups. It is much eas­i­er to do this, because the night lens­es are tougher, do not turn out, do not stick to the fin­ger­tips. The first time the lens­es must be worn under the super­vi­sion of a doc­tor.

Why are night contact lenses dangerous?

- Night lens­es do not pose a dan­ger to vision and health in gen­er­al. They are no more dan­ger­ous than ordi­nary soft lens­es. The main thing to remem­ber is that you can wear such lens­es for no more than 10 hours, and wear­ing less than 7 hours will not bring the expect­ed effect.

Can children wear these lenses?

- Night hard lens­es can be worn by chil­dren from 6 years old, but only on the rec­om­men­da­tion of a pedi­atric oph­thal­mol­o­gist. The main prob­lem is the dif­fi­cul­ty of putting them on and get­ting used to wear­ing them for a long time. In addi­tion, the child should be dis­ci­plined. If he does not put on lens­es at night, visu­al acu­ity will not be restored dur­ing the day.
