Unokukhetha njani izikhanyiso zelanga?

Ukufunyanwa kweso sixhobo, okuyimfuneko kwientsuku zelanga, njengezibuko zelanga, yinto enokuyilungelelanisa kunye nokuqaphela indlela yokugqibela yefashoni. Iiglasi zeguliti aziyi kuba yinto efanelekileyo yokuhlobisa, kodwa nokukhuselwa okuthembekileyo kwamehlo kumonakalo owenzela i-ultraviolet. Ngoko, njani ukhetha iilazi zokukhanya?

Unokukhetha njani ama-glass sun?

Isisombululo kulo msebenzi obalulekileyo siqala ngcaciso yenqaku apho iilensi zeglasi zakho ziza kwenziwa khona. Kukho iindlela ezimbini kuphela: iiglasi okanye iplastiki.

Iplastiki ngokwayo ayikhuseli kumbane we-UV, ngoko ukusebenza kweziglasi ezinjalo kuxhomekeke ngokupheleleyo kwiifayile ezisetyenziswe kuyo. Ama-lenses avela kule ngcaciso akhwanyizwa lula, ngoko xa uthenge ezi glasi, kufuneka ufike ngokukhawuleza ukuthenga ikhava efanelekileyo. Nangona kunjalo, inzuzo yeplastiki kukuba ikhuselekile, amaphuzu anjalo aqhubeki xa aphuhliweyo abe ngamaqhezu amancinci, kodwa aphekwe nje ngebhubhiso yeeqhekeza.

I-Glass, ngokungafani neplastiki, ayivumeli ukupasa kwe-ultraviolet konke, ngoko unokuthenga iziglasi ezifana nokuba zifihliwe okanye zifihliwe kakhulu. Iilensi zeglasi aziqhathaniswa, kodwa ziyakwazi ukuphazamiseka, eyingozi kakhulu. Ngoko ke, abo baqhuba imoto okanye bahlanganyele kwimidlalo esebenzayo, iziglasi ezinjalo akufanele zigqwe. Ukongezelela, iglasi ibaluleke ngaphezu kweplastiki, eyenza umthwalo owongezelelweyo kwibhulorho ekhaleni.

Ngoku qwalasela indlela yokukhetha izilwanyana zokukhanya, ngokuxhomekeka kwinqanaba lokukhusela kwabo. Kukho iintlobo ezi-3 eziphambili zezibuko.

1. Iiglasi zokuqala zokuzicoca, ziphawulwe "I-Cosmetic". Ezi glasi zidlula ukusuka kuma-51 ukuya kwi-100% yemitha kwaye zigqatswa xa ilanga lingabonakali kakhulu, umzekelo, ngokuhlwa okanye kwimozulu.
2. Inqanaba lesibini lokukhusela - Jikelele - iiglasi zemihla ngemihla zembethe kwisixeko. Bavimba ukususela kuma-50 kuya ku-70% wemitha ye-ultraviolet.
3. Inqanaba lesithathu yiziglasi eziphezulu zokukhusela ii-UV. Ezi ngqungquthela zivimbela ngokupheleleyo imimangaliso engabonakaliyo kwaye zinokugqithwa kwiholide elwandle okanye ezintabeni.

Iinkcukacha ngezinga lokukhusela ziyafumaneka kwilebula, kunye nesatifikethi esitholakalayo kwizibane zokukhanya eziphezulu. Ngokuqhelekileyo kukho ulwazi malunga nezibonakaliso ezimbini zokukhusela kwi-UV-ray: I-A ne-B. Xa uphendula umbuzo othi iziphi izilangazi zokuzikhethela, ii-ophthalmologists zincoma ukuthenga loo mizekelo apho izibonisi zombini zi ngaphezu kwama-50%.

Unokukhetha njani ukuma kwelanga?

Kodwa iiglasi zekhwalithi azikwazi ukugcina impilo yakho yamehlo ngokukhuselekileyo, kodwa kwakhona ibe yindawo yokufikelela ephezulu kakhulu ehlobisa kwaye igcwalise umfanekiso. Umgaqo ophezulu xa ukhetha izibuko zelanga: ungabathengi umumo ofanayo nobuso bakho. Ngokomzekelo, amantombazana afuneke athenge ama-glass sun. Ifom ye-universal, efanelwe phantse wonke umntu, i-teardrop, oko kukuthi, izibuko zelanga ze-aviator.

Xa ukhetha umlo wesigubungelo kunye namacici, kufuneka kwakhona ukuziqhelanisa kumpawu zobuso. Ngoko ke, amantombazana anemimandla emikhulu ayifanelekile le mijelo yeengqungquthela kunye neembalo ezininzi, ngeli xesha amantombazana anemigangatho emincinci aya kuhobisa iiglasi kwiimeko ezincinci zetsimbi. Imfashini kwiminyaka embalwa edlulileyo, ukubonisa izibuko zelanga kunye nezibambiso ezincinci ziya kuba lukhetho olugqibeleleyo xa ungathandabuzeki ukuba yeyiphi ifom iya kuhambelana nawe.

Kufanelekile ukubeka ingqalelo ebubanzi beglasi. Akufanele baqhube ngamandla phezu kwamaphethelo ebuso, kodwa abafanelekanga. Umlinganiselo ophezulu: ububanzi befom ye-1.5-2 cm ubukhulu ngaphezu kobubanzi bendawo kwindawo apho iiglasi zigugile khona. Ukuphendula ingxelo ngale meko kuya kunceda ukulinganisela nokuvumelanisa ubume bomzimba.
