Men take notice of a woman's breasts upon first meeting -Study
The check list emerged amid a look at men's impressions of women they meet for the first time, or pass in the street and vice versa.
The results show that the stereotypical guy with eyes for only one thing seems to be disappearing, and a more soulful modern man is taking his place.
As many as 70 per cent of the 1,000 men who took part in the study revealed eyes are what they gaze at first.
Smile was second, and breasts were third, while hair and weight were also among the first things men notice.
A large percentage of the 1,000 women who also took part in the study opted for an eyes first approach to forming impressions.
A spokesperson for Murine eye drops, which commissioned the study, said: 'Eyes usually tell us a lot about a person so we aren't surprised that eyes are what draws us to the opposite sex.
'Until you get to talk to a person for the first time, all you have to go on is the way they look, a simple smile is also something that both genders notice in each other.
It goes to show that men and women are more alike than many would previously had thought.
'This study almost crushes the common stereotype that the first thing men look at is a woman's chest, however it came third on the list so it's not quite a changed habit.
'Getting attention from the opposite sex boosts your confidence so using your eyes and smile in positive ways really gives you a good chance of getting welcomed attention, even if it's innocent.'
The study also found following the eyes, smile, breast, hair, weight routine men's eyes are drawn to a woman's legs, dress sense, bottom, height and skin condition.
The results from the women who took part in the research found after a man's eyes, they take in their smile, height and hair.
Following that, they run the rule over their dress sense, weight, skin face shape and then finally, his bottom.
It also emerged, worryingly, one in four men have even been caught out looking at a woman by their other half.
And seventeen per cent of women admit they had walked past their destination and had to turn around and walk back after spotting a good-looking man.
The study also found that two thirds of men are confident enough to tell a stranger they had a specific nice feature
One in two women said the same.
The study also found that rather embarrassingly, one in five men have walked into another person when their eyes have landed on the opposite sex.
A distracted one in ten men has walked in to a lamp post while watching an attractive woman walk past them.
Men also find that Cheryl Cole has the most attractive eyes in the celebrity world, while women voted for George Clooney.
