\u00centr-o lume supertehnologizat\u0103, \u00een care leg\u0103tura tuturor cu to\u0163i este obligatorie, indiferent de v\u00e2rst\u0103,copii no\u015ftrii sunt conecta\u0163i, poate mai mult dec\u00e2t noi, la aceast\u0103 realitate.<\/p>\n

C\u00e2nd ritmul de inven\u0163ie al produselor digitale este \u00eentr-o permanent\u0103 revolu\u0163ie iar lumea magic\u0103 a reclamelor ne bombardeaz\u0103 pe to\u0163i cu oferte de nerefuzat, dorin\u0163ele copiilor no\u015ftrii, gliseaz\u0103 rapid de la jocuri lego la dispozitive inteligente cum ar fi , smartphonul, tablete, laptopuri, desktopuri, televizoare 3D, 4D, pe scurt tehnologii de ultim\u0103 or\u0103, ce toate au terminale (ecrane) ce le solicit\u0103 vederea mai mult dec\u00e2t ne d\u0103m seama.
\n Toate aceste \u201dminuni\u201d sunt extrem de accesate de copii, multe ore pe zi, ei fi ind extrem de adaptabili \u015fi de familiariza\u0163i cu tot ce este nou \u00een domeniu.<\/p>\n

DAR OARE, ACESTE EXPUNERI LA EFORT VIZUAL PRELUNGIT, POATE CAUZA PROBLEME DE VEDERE COPIILOR NO\u015eTRII?<\/strong><\/p>\n

Cu siguran\u0163\u0103, da ! Sindromul oboselii induse de utilizarea \u00eendelungat\u0103 a acestor ecrane a computerelor, tabletelor, smartphonului, televizorului, denumit \u015fi Computer Vision Syndrom (CVS), poate fi dezvoltat mai acut \u00een r\u00e2ndul copiilor \u015fi adolescen\u0163ilor.
\n(conform unui studiu al AOAAsocia\u0163ia American\u0103 a Optometri\u015ftilor).<\/p>\n

\u015etim cu to\u0163ii c\u0103, activit\u0103\u0163ile pl\u0103cute, pot \u0163ine copiii \u00een fa\u0163a monitorului p\u00e2n\u0103 la epuizare, ei nerealiz\u00e2nd imediat, efortul la care se supun.
\nRegula „20-20-10\u201d, adic\u0103 o pauz\u0103 la fi ecare 20 de minute timp \u00een care privim un obiect afl at la 20 metri timp de 10 secunde, regul\u0103 ce ne confer\u0103 o relaxare a ochilor \u00een timpul solicit\u0103rii vizuale sus\u021binute, este vital\u0103 atunci c\u00e2nd solicitarea este ridicat\u0103. Aceast\u0103 regul\u0103 este reco- mandat\u0103 de speciali\u015ftii vederii, dar din p\u0103cate prea pu\u0163in aplicat\u0103. <\/p>\n

Prin structura lor, ochi\u015forii copiilor, sunt mult mai adaptabili dec\u00e2t ai adul\u0163ilor \u015fi pot tolera un disconfort vizual, nerealiz\u00e2nd instalarea lui. Astfel, \u00een cazul expunerii \u00eendelungate \u00een fa\u0163a monitorului, apare o suprasolicitare care poate induce o imagine neclar\u0103 datorat\u0103 unui spasm acomodativ, poate intervenii o senza\u0163ie de usturime ocular\u0103 ( nisip \u00een ochi) datorat\u0103 usc\u0103ciunii suprafe\u0163ei oculare, deoarece reflexul de clipire se diminueaz\u0103 iar umectarea ochilor prin clipire nu se realizeaz\u0103 corespunz\u0103tor, precum dureri de cap sau o senza\u0163ie de oboseal\u0103 neasociat\u0103 cu activit\u0103\u0163i fi zice. Aceeste simptome pot fi accentuate \u015fi datorit\u0103 str\u0103lucirii ridicate sau a contrastului prea puternic al ecranelor. De aceea reglarea intensit\u0103\u0163ii \u015fi contrastului este important\u0103 pentru cre\u015fterea confortului \u00een timpul privirii terminalelor de orice fel. La fel de important\u0103 este \u015fi postura pe care copiii o au c\u00e2nd utilizeaz\u0103 aceste terminale. \u00cen general, trebuie urm\u0103rit ca distan\u0163a fa\u0163\u0103 de o tablet\u0103, de exemplu, s\u0103 fi e de 40-45 cm, fa\u0163\u0103 de monitor peste 70 cm, fa\u0163\u0103 de ecranul televizorului de peste 3,5 metri, \u00een func\u0163ie de m\u0103rimea lui – cu c\u00e2t este mai mare ecranul cu at\u00e2t se m\u0103re\u015fte distan\u0163a.<\/p>\n

Deoarece majoritatea sta\u0163iilor de lucru sunt ajustate pozi\u0163iilor adul\u0163ilor, trebuie s\u0103 urm\u0103rim ca atunci c\u00e2nd copiii se a\u015feaz\u0103 \u00een fa\u0163a calculatorului unghiul de vizualizare al ecranului s\u0103 fi e cu 15% mai jos, refl exiile luminilor ambientale sau a luminii naturale s\u0103 nu se refl ecte \u00een ecran iar pozi\u0163ia lor pe scaun s\u0103 permit\u0103 atingerea podelei cu picioarele.<\/p>\n

Tabletele sau smartphone-urile sunt \u015fi mai solicitante pentru ochi\u015forii copiilor no\u015ftrii, datorit\u0103 faptului c\u0103 sunt \u0163inute mult prea aproape de ochi, fapt ce induce un efort vizual \u015fi
\nmai mare.<\/p>\n

Pauzele mai dese, precum \u015fi aplicarea regulei „20-20-10\u201d, pot prevenii sau diminua aceste probleme ce pot duce la instalarea sindromului visual datorat computerului\u2013C.V.S.- Cum cadourile din acest segment, aduc bucurie \u015fi fericire copiilor no\u015ftrii, respect\u00e2nd o atitudine corect\u0103 fa\u0163\u0103 de utilizarea acestor dispozitive, va face s\u0103 \u00eemp\u0103c\u0103m dorin\u0163a lor de a sta c\u00e2t mai mult \u00een fa\u0163a unei tablete cu s\u0103n\u0103tatea ochi\u015forilor lor.<\/p>\n
