My glasses is weak.

I'm starting to get the feeling that the glasses I wear today is gonna break within the next few weeks.... I tend to adjust it and it irritates my nose bridge and the top of my ears which it hangs from.

It could be from me being tired staring at the computer all day long or because the lens are starting to scratch up or more likely it's about to break like my old glasses...

Recap : My old glasses broke when I tried to adjust the bridge... I applied maybe too much force over it's worn out brittle frame and broke the glasses in half....
