Umehluko phakathi kwe-1.56 mid-index kanye namalensi ajwayelekile angu-1.50 ubuncane.
Amalensi anale nkomba anciphisa ukujiya kwamalensi ngamaphesenti angu-15.
Amafreyimu/izibuko zamehlo ezigcwele rim ezigqokwa ngesikhathi semidlalo zifaneleka kakhulu kule nkomba yelensi.
Ngokuvamile, ilensi eyindilinga ijiyile; ukuthwebula nge-lens eyindilinga kuzokonakala.
I-aspheric lens, izacile futhi ilula, futhi yenza isithombe esingokwemvelo nesingokoqobo.
Ukukhanya kwelanga kwenziwa ngokubomvu, okuwolintshi, okuphuzi, okuluhlaza okotshani, okuluhlaza okwesibhakabhaka, kwe-indigo nokukhanya oku-violet. Uma ihlanganiswa, iba ukukhanya okumhlophe esikubonayo. Ngayinye yalezi inamandla ahlukene kanye nobude begagasi. Imisebe ekugcineni ebomvu inamaza amade amade namandla amancane. Ngakolunye uhlangothi, imisebe eluhlaza okwesibhakabhaka inobude obufushane wamaza namandla engeziwe. Ukukhanya okubukeka kumhlophe kungaba nengxenye enkulu eluhlaza okwesibhakabhaka, engadalula iso enanini eliphakeme lobude begagasi ukusuka ekugcineni okuluhlaza okwesibhakabhaka kwe-spectrum.
1. Ukukhanya okuluhlaza kuyo yonke indawo.
2. Imisebe yokukhanya ye-HEV yenza isibhakabhaka sibukeke siluhlaza.
3. Iso alilungile kakhulu ekuvimbeni ukukhanya okuluhlaza okwesibhakabhaka.
4. Ukuchayeka ekukhanyeni okuluhlaza kungase kwenyuse ingozi yokonakala kwe-macular.
5. Ukukhanya okuluhlaza kunomthelela ekucindezelekeni kwamehlo edijithali.
6. Ukuvikela ukukhanya okuluhlaza kungase kubaluleke nakakhulu ngemva kokuhlinzwa kwe-cataract.
7. Akuwona wonke ukukhanya okuluhlaza okwesibhakabhaka okubi.
Amalensi okunciphisa ukukhanya okuluhlaza akhiwa kusetshenziswa i-pigment enelungelo lobunikazi engezwa ngqo kumalensi ngaphambi kwenqubo yokusakaza. Lokho kusho ukuthi izinto ezinciphisa ukukhanya okuluhlaza okwesibhakabhaka ziyingxenye yayo yonke impahla yelensi, hhayi nje i-tint noma ukunamathela. Le nqubo enelungelo lobunikazi ivumela ukukhanya okuluhlaza okwesibhakabhaka okunciphisa amalensi ukuthi ahlunge inani eliphezulu lakho kokubili ukukhanya okuluhlaza okwesibhakabhaka nokukhanya kwe-UV.
