Beauty is perceptual: Julianne Moore

Actress Julianne Moore's classmates thought she looked prettier when she ditched her glasses for contact lenses when she was 16.

The "Still Alice" actress still doesn't understand why her classmates didn't think she was "terribly pretty" until she ditched her spectacles because she was still the same person on the inside.

"That's the thing about beauty, it's perceptual, not about what you look like," femalefirst.co.uk quoted Moore as saying.

"I had glasses and no one thought I was terribly attractive. Then suddenly, I wore contacts and everyone thought I was pretty. But I was the same person perceived as pretty," she added.

The 54-year-old, who has children Cal, 17, and Liv, 12, with husband Bart Freundlich, has ruled out undergoing cosmetic surgery and can't understand why people think it will make them look younger.

She said: "I don't know why people have work done. It doesn't make them look younger, it just makes them look like they've had work done. You're never going to look like you did at 25. What are you going to do about it?"
