okay .
in mall they are giving u a real transition lenses .
shop sg wang thy give u photochromic lenses .
Transition lenses is branded and quality , thy change colour darker , shorter time to get dark , and clear . have no prob after wearing more than 1 year , it still as clear as normal clear lenses (indoor)
photochromic lenses there is alot local brand , quality is cheap , change colour slow , and nott dark compare to branded lenses . coating also one of the feature . local lenses have a low quality of coating . branded such as HOYA ESSILOR ETC comes with very good coating with atleast 2 years warranty

is not rental . sg wang thy are giving cheap lenses , where normal customer thy don know . in mall thy give branded as promise .

if u really compare those lenses side by side , u will realise the diff colour . and after u use those cheap lens , it will have some tinted , and will not getting darker since the 1st day u bought

retail RM600 , havent discount , depends on shop how much they discount for u .

yes i did , but is private and confidential

i work optical 10 years , stop last year .

299 i don think is essilor or hoya transition

hoya dont comes with lifetime warranty .
don ask for country lens , ask for the brand
