Ruvara upofu

Ruvara hupofu ndiko kusakwanisa kuona mamwe mavara munzira yakajairwa.

Ruvara kupofumadza kunoitika kana paine dambudziko nemavara mune mamwe maseru etsinga eziso iro rinonzwisisa ruvara. Aya maseru anonzi macone. Ivo vanowanikwa mune yakajeka-inonzwika tambo yetishu kumashure kweziso, inonzi iyo retina.

Kana imwe chete pigment isipo, unogona kunetseka kuudza musiyano uripo pakati petsvuku negirini. Iyi ndiyo mhando inowanzoonekwa yehupofu hwemavara. Kana imwe pigment isipo, unogona kunetseka kuona bhuruu-yero mavara. Vanhu vane bhuruu-yero ruvara bofu kazhinji vane matambudziko ekuona matsvuku uye magidhi, futi.

Rudzi rwakanyanya kwazvo rwehupofu hwemavara iachromatopsia. Ichi chiitiko chisingawanzoitika umo munhu asingakwanise kuona chero ruvara, chete mumvuri wegrey.

Hazhinji kupofomara kwemavara kunokonzerwa nedambudziko remajini. Vanenge munhu mumwe mugumi varume vane imwe nzira yekusaona kwemavara. Vakadzi vashoma kwazvo vakapofomara.

Mushonga wehydroxychloroquine (Plaquenil) unogona zvakare kukonzera kupofomara kwemavara. Iyo inoshandiswa kurapa rheumatoid arthritis uye mamwe mamiriro.

Zviratidzo zvinosiyana kubva pamunhu kumunhu, asi zvinogona kusanganisira:

• Dambudziko rekuona mavara uye kupenya kwemavara nenzira yakajairwa
• Kusakwanisa kuudza musiyano uripo pakati pemumvuri wakafanana kana iwo akafanana mavara

Kazhinji, zviratidzo zvakapfava zvekuti vanhu vanogona kusaziva kuti vakapofumara. Mubereki anogona kucherechedza zviratidzo zvebofu bofu kana mwana mudiki ari kutanga kudzidza mavara.

Inokurumidza, padivi-ne-parutivi kufamba kweziso (nystagmus) uye zvimwe zviratidzo zvinogona kuitika mune zvakakomba zviitiko.

Anopa hutano hwako kana weziso nyanzvi anogona kutarisa ako mavara ekuona munzira dzinoverengeka. Kuedzwa kwemavara bofu chinhu chinowanzoitika pakuongorora kweziso.

Iko hakuna kuzivikanwa kurapwa. Anokosha ekubatanidza lensi uye magirazi anogona kubatsira vanhu vane ruvara kupofumadza vataure musiyano uripo pakati pemavara akafanana.

Ruvara upofu mamiriro ehupenyu hwese. Vanhu vazhinji vanokwanisa kuchinjira kwairi.

Vanhu vane colorblind vanogona kusakwanisa kuwana basa rinoda kugona kuona mavara nenzira kwayo. Semuenzaniso, magetsi, vapendi, uye vagadziri vefashoni vanofanirwa kugona kuona mavara nenzira kwayo.

Fonera wako mupi kana weziso nyanzvi kana iwe uchifunga kuti iwe (kana mwana wako) unogona kuva neruvara kupofomara.
