This may come off as vanity, but like many aspects of personal grooming, it's the small things that add a lot both in terms of reception and perception. And I've found that being perceived as smart or professional or hardworking is much more important than any of those things.
I don't need glasses, as far as I'm aware I have perfect eyes. But I'm considering purchasing some to appear more professional. I automatically assume that a person wearing glasses is smarter than a person without.
Will I look smarter or more professional in glasses?
And will it affect my chances of getting hired/promoted?
Edit: The type of glasses I'm thinking have anti-glare lens coating. They're not lens-less or useless, they just aren't required for seeing.
