Unugyada wax soo saarka muraayadaha muraayadaha kuwaas oo u beddela muraayadaha badh-dhammeedka muraayadaha la dhammeeyey iyadoo loo eegayo sifooyinka saxda ah ee warqadda dhakhtarku qoray.
Shaqada hagaajinta ee shaybaarada ayaa noo suurta galinaysa inaan bixino kala duwanaansho balaadhan oo ah isku dhafka indhaha ee baahiyaha xirayaasha, gaar ahaan marka la eego hagaajinta presbyopia. Shaybaarada ayaa mas'uul ka ah inay dusha sare ka saaraan (shiilid iyo turxaan bixin) iyo dahaarka (midabaynta, xoqidda, lidka-milicsiga, ka-hortagga-smudge iwm) muraayadaha.
Tusmada dib-u-celinta 1.60
Walaxda muraayada lenska ee ugu dheelitiran ee ugu fiican oo leh saamiga ugu badan ee tusaha muraayada 1.60
suuqa. MR-8 wuxuu ku habboon yahay lensiska indhaha ee xoogga leh waana heer cusub oo walxaha lenska indhaha ah.
Isbarbardhigga dhumucda muraayadaha 1.60 MR-8 iyo 1.50 CR-39 muraayadaha (-6.00D)
MR-8 | Polycarbonate | Acrylic | CR-39 | Muraayadaha Crown | |||||||||||
Tusmada dib-u-celinta | 1.60 | 1.59 | 1.60 | 1.50 | 1.52 | ||||||||||
Abbe number | 41 | 28-30 | 32 | 58 | 59 |
Tilmaanta refractive sare iyo nambarka Abbe ee sarreeya labaduba waxay bixiyaan waxqabad muuqaal ah oo la mid ah muraayadaha muraayadda.
Alaabta sare ee Abbe sida MR-8 waxay yaraynaysaa saamaynta priismka (aberration chromatic) ee lenses waxayna siisaa isticmaal raaxo leh dhammaan kuwa xidhan.
Xabagta MR-8 si isku mid ah ayaa loogu dhejiyay caaryada dhalada. Marka la barbar dhigo muraayadaha polycarbonate ee la isku duro,
Muraayadaha MR-8 resin waxay muujinayaan culeyska walaaca ugu yar waxayna bixiyaan aragti cad oo aan diiqad lahayn.
