Font renders thicker in browsers

I am using the Open Sans font on a web site, but it appears much thicker in all browsers than in Adobe Illustrator (see attached images). Why is this and is there any way I can get the font in the browser to display "thinner" please?

Illustrator

Browser

Note Both the browser and Illustrator are rendering the Semibold weight (600)

The issue was with aliasing. The following css solution will work for safari, chrome and firefox:

-moz-osx-font-smoothing: grayscale;
-webkit-font-smoothing: antialiased;
