ʻO nā aniani nā lens i hoʻokomo ʻia i loko o kahi kiʻi a hoʻohana ʻia i mua o ka maka no ka pale a i ʻole nā mea hoʻonaninani.Hiki ke hoʻohana ʻia nā aniani no ka hoʻoponopono ʻana i nā pilikia ʻike like ʻole, e like me ka ʻike kokoke, ʻike mamao, astigmatism, presbyopia a i ʻole strabismus, amblyopia a pēlā aku.
No laila he aha kāu ʻike e pili ana i nā lens?Pehea e koho ai i ka lens i kūpono iā ʻoe iho?E hoʻomaka kākou me ʻekolu mau mea:
Lens transmittance: ʻO ke kiʻekiʻe o ka transmittance, ʻoi aku ka maikaʻi o ka mālamalama
Ke ʻano o ka lens:
E hoʻololi i ka lens kala: hiki ke hoʻololi i ka lens kala ke hoʻololi i ka transmittance ma o ka lens hoʻololi i ke kala, hoʻololi i ka maka o ke kanaka i ka loli o ke kaiapuni, hoʻemi i ka luhi ʻike, pale i ka maka.
ʻO ka leki kuhikuhi refractive kiʻekiʻe: ʻO ke kiʻekiʻe o ka kuhikuhi kuhikuhi, ʻoi aku ka lahilahi o ka lens.
Nā lens holomua: Hoʻololi i nā hiʻohiʻona a me nā mamao āpau
Maka aniani:
ʻOi aku ka pale ʻana ma mua o nā lens ʻē aʻe, akā kaumaha.
ʻO ka leki polimer resin:
ʻOi aku ka māmā ma mua o nā aniani aniani, ʻaʻole maʻalahi ka haki ʻana i ka hopena, akā haʻahaʻa ka paʻakikī, maʻalahi ke ʻoki.
ʻO nā lens PC:
ʻO ka inoa kemika PC he polycarbonate, me ka paʻakikī, ʻike ʻia ʻo "space piece", "universe piece", "safety lens", ʻaʻole maʻalahi e haki.ʻO ka hapalua wale nō ko lākou kaumaha e like me nā lens resin maʻamau, a hoʻohana nui ʻia i nā lens ʻike pōkole no nā keiki a i ʻole nā maka maka no nā mea pāʻani.
ʻO ke kukui uliuli:
Ua ʻike nā haʻawina e hiki i ke kukui polū ke hoʻopōʻino mau i ka retina, e hōʻemi ana i ka macular degeneration.I kēia manawa, nui nā kukui polū i nā kumu kukui hana.Hiki i nā lens kukui ʻulaʻula ke pale i nā maka, e hōʻemi i ka pōʻino i hana ʻia e ka kamepiula a me ke kumu kukui LED.
Polarization:
ʻO nā hiʻohiʻona o ke kukui polarized ka mea maʻamau e hoʻopau i ka mālamalama i hōʻike ʻia a me ka mālamalama i hoʻopuehu ʻia, kaohi i ke kukui ikaika, hoʻokaʻawale i ke kukui ultraviolet ʻino, ʻoi aku ka maʻalahi o ka ʻike, ka pale ʻana i ka hopena, ka pale ʻana.
Ka uhi ʻana o nā leki:
Hiki iā ia ke hōʻemi i ka mālamalama i hoʻohālikelike ʻia o ka ʻili o ka lens, hoʻomaʻamaʻa i ka mea, hoʻemi i ke kukui i ʻike ʻia o ke aniani, hoʻonui i ka transmittance o ka mālamalama.
