Tilmaamaha Alaabta
1.Waa maxay muraayadda dhammaatay?
Muraayadaha leh awoodo dioptric kala duwan ayaa laga samayn karaa hal lens oo dhammays tiran.Qallooca sagxadaha hore iyo kan danbe ayaa tilmaamaya in muraayadu yeelan doonto awood dheeri ah ama laga jaray.
Lens-dhammeedka dhammaatay waa bannaan ceeriin oo loo isticmaalo in lagu soo saaro muraayadda RX ee ugu shaqsiyeysan si waafaqsan warqadda bukaanka.Awoodaha dawo ee kala duwan ayaa codsanaya noocyada muraayadaha ee dhammays tiran ee kala duwan ama qalooca salka.
2. Waa maxay muhiimada muraayad-dhammeedka wanaagsan u leeyahay wax soo saarka RX?
①Heerka sare ee saxnaanta awoodda iyo xasiloonida
② Heer sare oo u qalma tayada la isku qurxiyo
③ Astaamaha indhaha sare
④ Saamaynta midabaynta wanaagsan iyo natiijooyinka dahaarka adag/AR
⑤ Xaqiiji awoodda wax-soo-saarka ugu badan
⑥ gaarsiinta waqtiga
Ma aha oo kaliya tayada dusha sare, muraayadaha badh-dhammeeyay waxay aad diiradda u saarayaan tayada gudaha, sida cabbirada saxda ah iyo kuwa deggan, gaar ahaan muraayadda caanka ah ee xorta ah.
3.Tusaale 1.56:
1.56 lenses index dhexe waa mid ka mid ah muraayadaha ugu caansan adduunka oo dhan.Tani waxay go'aamineysaa in Aogang 1.56 lenses-ka-aragga ah ay leeyihiin astaamaha indhaha ee ugu caansan:
Dhumucda: Isla diopters-yada, 1.56 lenses ayaa ka khafiifsan doona muraayadaha CR39 1.499.Sida kororka diopters-ka, faraqa ayaa sii weynaan doona.
② Saamaynta Muuqaalka: Marka la barbardhigo muraayadaha index sare, 1.56 lenses waxay leeyihiin qiime sare oo ABBE ah, waxay ku siin karaan khibrad muuqaal ah oo raaxo leh.
③Dahaarka: Muraayadaha aan dahaadhka lahayn ayaa si sahal ah hoos loogu dhigaa oo waxay u soo bandhigaan xagashada, muraayadaha dahaarka adag waxay saamayn karaan iska caabbinta.

4. Waa maxay faraqa u dhexeeya HC, HMC iyo SHC?
| Dahaarka adag | Daahan AR / Daahan badan oo adag | daahan Super hydrophobic |
| waxay ka dhigtaa muraayadda aan dahaadhka ahayn mid adag oo kordhisa iska caabbinta nabarrada | waxay kordhisaa gudbinta muraayadda waxayna yaraynaysaa milicsiga dusha sare | muraayada waxay ka dhigtaa mid aan biyuhu ahayn, antistatic, silbasho lid ku ah iyo caabbinta saliidda |
