Too late - I'm already wearing glasses.
But believe me, they don't make it easier to distinguish those tiny icons... They could really be 4 or 5 pixels higher & wider. (The icons, not the glasses!!)
Concerning the new verisons posted by dstruct2k: The new "locked" icon has far too little contrast; it's almost impossible to tell apart from the "no new" icon. The original is better because you can see the "x" through it.
And I agree with PMB on that dancing lock icon - it's great for a laugh, but a lock should really look a tad forbidding and not inviting...
...so much for my $ 0.02...
