Okay. Oculo Focalis shouldn't be too hard to master. Ella decided to work on the incantation first and get that down. "Oculo Focalis...Oculo Focalis...Oculo Focalis....Oculo Focalis..." She knew Airey said they wouldn't mess up their eyesight or anything but she still wanted to be cautious. She needed her eyes for Quidditching reasons, obviously. Besides, she quite liked being able to see.

Next was the wand movement. A slight swish and a tap on closed eyelids, yeah? She could handle that. Swish and tap. Swish and tap. Swish and tap.

She was ready. Sort of. Oh Merlin, please let this work.

Ella held up her wand, closed her eyes and said, "Oculo Focalis!" Swish and tap!

...Did it work? Her eyes felt a bit different but she'd need to check the chart again to be sure.
