1 lens Ibice bibiri ni iki?
Bifocals ni lens ifite imbaraga ebyiri zitandukanye zo gukosora.Bifocals isanzwe yandikiwe presbyopes
bisaba gukosorwa kuri myopiya (nearsightedness) cyangwa hyperopiya (farsightedness) hamwe cyangwa idakosowe na astigmatism (iyerekwa rigoretse bitewe na lens cyangwa cornea idasanzwe).Intego yibanze yinteguza ni ugutanga icyerekezo cyiza hagati yintera niyerekwa.
Mubisanzwe, urareba hejuru kandi unyuze mugice cyintera ya lens mugihe wibanze kumanota kure, nawe
reba hasi unyuze mubice bibiri bya lens mugihe wibanda kubintu byo gusoma cyangwa ibintu muri 18
santimetero y'amaso yawe.Biremewe muri rusange ko Benjamin Franklin yahimbye bifocal.Bifocal ikunze kugaragara cyane muri iki gihe ni Straight Top 28 Bifocal ifite umurongo ugororotse hejuru hamwe na radiyo 28mm.Hariho ubwoko bwinshi bwiburyo bwo hejuru buboneka uyumunsi harimo: Straight Top 25, Straight Top 35, Straight Top 45 hamwe na Executif (Umwimerere wa Franklin Seg) ikora ubugari bwuzuye bwa lens.
Usibye ibice byombi bigororotse hari ibice bibiri byuzuye birimo Icyiciro cya 22, Icyiciro cya 24, Icyiciro cya 25
Icyiciro cya 28 cyahujwe (nta gice gisobanutse).
Ibyiza kumurongo uzenguruka ni uko hari amashusho make asimbuka nkuko umuntu ahinduka kuva kure kugera mugice cyegereye lens.

2 lens Icyuma gifotora ni iki?
Lens ya Photochromic izwi kandi nka "lensensensens lens".Ukurikije ihame ryo guhinduka kwihindagurika ryamabara yumucyo, lens irashobora kwijimye vuba mumirasire yumucyo na ultraviolet, igahagarika urumuri rukomeye kandi igakurura urumuri ultraviolet, kandi ikerekana kutabogama kumucyo ugaragara.Tugarutse ku mwijima, birashobora kugarura byihuse ibara ridafite umucyo, kwemeza ko lens yoherejwe.Lens rero ihindura ibara irakwiriye gukoreshwa murugo no hanze icyarimwe, kugirango wirinde urumuri rwizuba, urumuri ultraviolet, urumuri kumaso yangiritse.Ukurikije ihame ryo guhinduka kwihindagurika ryamabara yumucyo, lens irashobora kwijimye vuba mumirasire yumucyo na ultraviolet, igahagarika urumuri rukomeye kandi igakurura urumuri ultraviolet, kandi ikerekana kutabogama kumucyo ugaragara.Tugarutse ku mwijima, birashobora kugarura byihuse ibara ridafite umucyo, kwemeza ko lens yoherejwe.Lens rero ihindura ibara irakwiriye gukoreshwa murugo no hanze icyarimwe, kugirango wirinde izuba, urumuri ultraviolet, urumuri kumaso yangirika.

3) Ni irihe tandukaniro riri hagati ya HC, HMC na SHC？

Igifuniko gikomeye	AR gutwikira / Gukomera cyane	Igikoresho cyiza cya hydrophobique
ituma lens idafunze kandi ikongerera abrasion	byongera ihererekanyabubasha kandi bigabanya kugaragara hejuru	ikora lens idafite amazi, antistatike, anti kunyerera no kurwanya amavuta
