MY advise:
If you wear a spectacle, then you could use your photo without spectacle. Sometimes when you take photo with spectacle , the spectacle edges may hinder yr eye views, in that case you will require to take a photo at consulate office, that would delay yr interview by approx half an hour.
Dress formal and neat.
Maintain eye contact, talk confidently. Don't disappoint even if u get rejected.
