Con­tact lens­es are required to cor­rect near­sight­ed­ness, far­sight­ed­ness, and astig­ma­tism.^one and can be intend­ed for day, night or pro­longed use.

Lens­es also dif­fer in terms of wear­ing. Dis­tin­guish dai­ly lens­es and lens­es of planned replace­ment: two-week lens­es, month­ly and quar­ter­ly lens­es². There are ortho­ker­a­tol­ogy lens­es, one pair of which can be used for a year or more.

In terms of eye health, dis­pos­able con­tact lens­es are the safest. They do not require main­te­nance and are dis­posed of imme­di­ate­ly after use, and new ones are put on instead. The dis­ad­van­tage of such lens­es is the high price and insuf­fi­cient strength, designed for one phase of putting on and tak­ing off.

Month­ly sched­uled replace­ment lens­es are the most com­mon and in demand. They are strong, reli­able, but in a month they man­age to become cov­ered with a pro­tein coat­ing, and cracks and chips may appear on the sur­face. After 2–3 weeks of wear­ing such lens­es, a per­son begins to expe­ri­ence dis­com­fort in the eyes, and the lens­es need to be replaced.

Bi-week­ly lens­es com­bine the safe­ty of dai­ly lens­es with the reli­a­bil­i­ty of month­ly replace­ment lens­es.². That is why they are the safest method of vision cor­rec­tion for eye health. In two weeks, the lens­es do not have time to wear out, and pro­tein deposits do not accu­mu­late on the sur­face.

There are bi-week­ly reg­u­lar and extend­ed wear lens­es. Extend­ed wear mod­els can be left on at night if nec­es­sary, they are con­ve­nient, com­fort­able and much cheap­er than dai­ly lens­es. Spe­cial con­di­tions for wear­ing lens­es are always pre­scribed in the instruc­tions for them. With prop­er care, such lens­es will pro­vide high-qual­i­ty vision cor­rec­tion and the expect­ed effect.

1. Acuvue Oasys with Hydraclear Plus

Acu­vue brand lens­es are made from Senofil­con A sil­i­cone hydro­gel.

How to choose biweekly contact lenses

Choos­ing bi-week­ly con­tact lens­es is no dif­fer­ent from choos­ing lens­es of oth­er types. First of all, you need to con­sult an oph­thal­mol­o­gist. The doc­tor exam­ines the con­di­tion of your eyes, deter­mines the required opti­cal pow­er of the lens­es and the radius of cur­va­ture. When choos­ing, one should take into account the mate­r­i­al of man­u­fac­ture, the lev­el of mois­ture con­tent and oxy­gen per­me­abil­i­ty. The val­ue will have the mode of wear­ing you need: day­time or pro­longed. Nev­er choose your own con­tact lens­es for the first time. The selec­tion of lens­es and the first use should be under the super­vi­sion of a physi­cian.

Reviews of doctors about two-week contact lenses

Accord­ing to doc­tors, two-week lens­es are the most effec­tive and safe means of con­tact vision cor­rec­tion. These lens­es com­bine the best qual­i­ties and reli­a­bil­i­ty of long-wear lens­es with the safe­ty of dai­ly ones. As a rule, two-week lens­es are made of sil­i­cone hydro­gel, which is opti­mal­ly suit­ed to the cornea of ​​u200bu200bthe eye².

For two weeks of use, plaque from pro­teins and lipids does not have time to accu­mu­late on the lens­es, the lens dur­ing this time does not wear out, does not crack and does not dam­age the cornea. Two-week lens­es do not cause aller­gies and are suit­able for peo­ple with “dry” eyes and hyper­sen­si­tiv­i­ty.

Two-week lens­es, like oth­ers, have a num­ber of con­traindi­ca­tions for use. Doc­tors do not advise using lens­es for chron­ic eye dis­eases, chron­ic aller­gies, tuber­cu­lo­sis, severe dia­betes mel­li­tus, men­tal dis­or­ders and some dis­eases of the ner­vous sys­tem, as well as for stra­bis­mus of more than 15 degrees, xeroph­thalmia, lens sub­lux­a­tions and HIV.
