I bought 2 pair of glasses one year ago at queensway but didn't wear them at all, one is too flimsy and the other too heavy.
i have been wearing swissflex glasses since 2008. i have just got my 3rd pair of swissflex recently. the reason why i like about swissflex is, it is lightweight, the nose pad do not get green moss stuck on the nose pad after wearing it for years. the things i don't like about swissflex, my nose pad broke after 2 years and the replacement cost $18. i also need to wear ear hook cos the glasses will slip out easily. when i sweat, the ear hook will get expand and became loose after 3 months, need to replace that in every 3 months and each pair of ear hook cost $1.50.
i'm thinking of getting owndays air ultem glasses. it look so flexible, light and comfortable. but not sure about the quality.
