Iphone 5, iOS 7, Mob Safari 'reader' does NOT increase font size !! pl help !!

[Subu]

Hi

I use iPhone 5

I have moved to iOS 7.0.3

All legit, NO jailbreak

My old eyes need bigger font , especially for reading web pages

The Mobile (iPhone) safari , 'reader' on iOS 7 safari, does not seem to have its own native font size increase button

I am told to go to the iPhone settings - main settings on home screen, increase font size meaning, increase the general font size on ALL apps and places , which is not what is intended

Still even IF I have set the font to the max, the reader app size is not big enough

any tips / tricks would be most appreciated

TIA
regards
