Zooey Deschanel, of "New Girl," recently made an appearance at the PlayFest event. Photos from the red carpet at Monday night's soiree have us wondering: What is wrong with Zooey Deschanel's eyelid?

The 33-year-old "New Girl" star, who plays a teacher named Jessica Day on the Fox sitcom, stepped onto the red carpet Monday night at the 30th Annual PaleyFest in Los Angeles wearing a black and white striped dress with a bow on the chest. She looked comfortable in her usual cute-girl look, but the camera caught more than Deschanel's brunette fringe and red lips; when the actress closed her eyes, photographers snapped pics of what appeared to be a number of tiny bumps on her right eyelid.

It is unclear what exactly caused Zooey Deschanel's eye bumps at PaleyFest, or if they are the result of any one particular condition. But the photos definitely show that something was not exactly right. So what could have caused the actress's eye sore?

There are a number of plausible, mostly benign answers as to what was wrong with Zooey Deschanel's eye at PaleyFest.  

A stye

Most of us have had a stye at one point or another. While a somewhat unsightly and embarrassing, they're nothing to be worried about. A stye is a lump in or along the edge of the eyelid caused by an infection. It is usually a tender red lump that could be related to blepharitis, a common problem that causes inflammation of the eyelids. Styes usually take about a week to heal.

Chalazion

Much like a stye, a chalazion is a lump in the eyelid. They are usually larger than styes and may or may not hurt. These, too, are caused by a small infection, usually when a tiny oil gland inside the eye becomes clogged. Chalazia grow more slowly than styes and usually start as a firm lump or cyst under the skin of the eyelid.

Cyst

A cyst is a small pouch of tissue that can be full of fluid, pus or other material. They are common on the skin, including the eyelids, and can develop from a clogged gland. They are benign, but can be painful and change the appearance of the skin. Depending on where the cyst is, it can be drained or removed with surgery.

Milia

More common among children, milia are much like cysts in that dead skin becomes trapped in a pocket at the surface of the skin. Adults will usually develop milia on the face. They will most likely disappear after the first few weeks, but if not, doctors can remove them to improve the appearance.

Celebrities are not immune to minor inconveniences like styes and cysts now and then, and we applaud Zooey Deschanel for not letting vanity get the better of her. And really, a few bumps on the eyelid are no road block to a successful career anyways.
