EnChroma Glasses
EnChroma magirazi ndiwo mutsva wechiratidzo chekushanda chinobatsira vanhu (varume) vane ruvara rwebhuruu-ruvara rwehuni huri nani kuonga ruvara.
Kunyange zvazvo EnChroma isingavandudzi ruvara rwemhando yakakwana zvokuti munhu anogona kudarika ruvara rwehupenzi, inobatsira vanhu vane ruvara rwekunaka kuwana ruzivo rwezvakada kuva nemuvara. Semuenzaniso, EnChroma lenzi inogona kubatsira vanhu vane ruvara rwemavara kuti vawedzere kuonga zvinhu zvakadai semagetsi e-orange kana kuti lavender flower petal.
EnChroma isimbi yakagadziridzwa ipurasitiki inoputirwa nematanda anenge zana e dielectric material. Iyi lens inoshanda nekushambadzira dzimwe mazhenesheni emwenje anovhenekera kune vanhu vane ruvara rwebhuruu ruvara. Kunyanya kunyanya, kuburikidza uchishandisa machenekera akawanda, EnChroma lenzi inonyatsoita kuti kuve nekusvibiswa kwema optic nekudaro kuwedzera maonero emiti uye magidhi.
EnChroma hazvirevi kuporesa uye zvine dambudziko. Kutanga, zvinotora anenge maminitsi makumi matatu eEnChroma lenses kuti iite. Chechipiri, EnChroma magirazi anodhura kupfuura magirasi ega uye anogona kutora mazana mashoma madhora maviri. Chechitatu, EnChroma lensiti haichazovandudzi kushanda kwezuva nezuva nenzira ipi neipi inofadza.
Zvinofadza kuti EnChroma magirazi anogonawo kupfekedzwa nevanhu vasina colorblindness. Kune vanhu vane zviratidzo zvakajairika, EnChroma lens dzinoita kuti mavara ave mazhinji kana kuti "pop."
