The cornea is best described as which of the following?

The cornea is the eye’s transparent front surface that helps focus light. It’s a clear connective tissue membrane that provides a smooth curved surface, giving much of the eye’s refractive power to bend light as it enters. It’s avascular, which keeps it optically clear, with nutrients supplied from tears and the aqueous humor. This isn’t a muscle that controls pupil size, and it isn’t the inner lining of the eyelid, nor a vascular layer.
