A. Haʻahaʻa haʻahaʻa: ma muli o ke āpau ma waena o nā kaulahao mole, he liʻiliʻi ka helu o nā molekala no kēlā me kēia leo, e hoʻoholo ana i nā pono o ka lens resin: haʻahaʻa haʻahaʻa kikoʻī a me ke ʻano māmā, ʻo ia ka 1/3-1/2 o ka aniani aniani;
B. Helu hoʻopaʻapaʻa haʻahaʻa: CR-39 propylene diethylene glycol carbonate maʻamau, ʻo 1.497-1.504 ka helu kuhikuhi.I kēia manawa, ʻo ka index refractive kiʻekiʻe loa o nā lens resin i kūʻai ʻia ma ka mākeke makaaniani Shenyang he aspherical ultra-thin hardened film resin lens, refraction Hiki ke piʻi i ka 1.67, a aia i kēia manawa nā lens resin me ka index refractive o 1.74.
C. He haʻahaʻa ka paʻakikī o ka ʻili ma mua o ke aniani, a he maʻalahi ke ʻoki ʻia e nā mea paʻakikī.No laila, pono e paʻakikī.ʻO ka mea paʻakikī he silica, akā ʻaʻole maikaʻi ka paʻakikī e like me ka paʻakikī o ke aniani.No laila, pono e hoʻolohe ka mea hoʻohana i ka lens.mālama;
D. Maikaʻi ka elasticity.Ma muli o ke kaawale ma waena o nā kaulahao molekala, ʻo ka elasticity he 23-28 mau manawa o ka ʻāpana aniani.Hoʻoholo ʻia kekahi hiʻohiʻona nui o ka lau resin - ka hopena maikaʻi.Ua pāpā nā ʻāina ʻEulopa, ʻAmelika a me Iapana i nā keiki ma lalo o 16 makahiki mai ke komo ʻana i nā lens aniani;
E. Hana kōkua: Hiki ke hoʻohui ʻia no ka loaʻa ʻana o nā hana e like me ka pale ʻana i nā kukuna ʻino a me ka discoloration.
