Presbyopia e ama bokhoni ba motho ba ho bona haufi-ufi (menu, likarete tsa recipe, melaetsa ea selefouno).
Lilense tsa polarized:Edwin H. Land o ile a etsa lilense tse nang le polarized ka 1936. O ile a sebelisa sefe ea polaroid ha a etsa likhalase tsa hae tsa letsatsi. Polarization e fana ka matla a anti-glare le boiketlo bo ntlafetseng ba ho shebella. Bakeng sa ba ratang tlhaho, lilense tsa polarized li fana ka mokhoa oa ho natefeloa ke lintho tse ka ntle, joalo kaho tšoasa litlhapile lipapali tsa metsi, ka ho eketsa ponahalo.
Lilense tse tsoelang pele:Joalo ka li-bifocals le trifocals,lilense tse tsoelang peleho ba le matla a lilense tse ngata bakeng sa batho ba nang le bothata ba ho bona hantle libakeng tse fapaneng.
