Forget tall, dark, and handsome. It turns out women may prefer small, lightweight, and compact.

A recent study found that British women spend on average 12 hours more a week on their mobile phones checking emails, sending texts, or browsing social media than they do spending time with their partner.

Perhaps more disturbing is that the researchers found if people are unable to be on their phones, it leads to stress, anger and panic. A fifth of those surveyed said it would be harder to be without a phone for a week than their partner, and one in six said they were entirely dependent on their mobile phones.

The study, conducted by researchers with Bausch + Lomb Ultra contact lenses, also found that more than a quarter of adults check personal email on their phones, one in ten will check work email, and half will keep tabs on social media — during their honeymoon!

All this relationship strain may have another unintended result: eye strain.

“All of this interaction and addiction with our digital devices creates problems for our eyes,” Psychologist Chireal Shallow told The Sun. “More than half say their eyes feel tired at the end of the day.”
