Ho tsoela pele ho amohela litlhoko tsa batho ba fapaneng, re fana ka mefuta e fapaneng ea mefuta e meng ea lense.

Lipontšo tsena li khethehile hobane li ka sebelisoa ka likhalase tsa mahlaseli tsa magnetic clip-on ho matlafatsa tšireletso ea tsona. Hase feela hore moqapi ona o boloka likhalase ho tloha likhahla le tšenyo e 'ngoe, empa hape e sebetsa haholo ebile e bonolo ho e sebelisa. Likhalase tsena li ka u fa tšireletso e felletseng hore na u etsa mesebetsi ea letsatsi le letsatsi kantle.

Ka melemo e mengata ea likhalase tsa rona tsa mahlo le likhalase tsa letsatsi, o ka thibela ts'enyo ea UV mahlong a hau hantle ntle le ho ntlafatsa litaba tsa pono.
