Later, circular needles were invented, which can also be used to knit in the round: the circular needle looks like two short knitting needles connected by a cable between them.

Once the substance is removed, the burning and itching will subside and other symptoms will disappear relatively quickly.

There are a number of eye drops (e.g. Pataday, Zaditor, Alocril) eye drops can relieve the symptoms of itchy, watery eyes that you describe. Check with your doctor about trying this.
