请用英文写一封邮件给夏校，内容如下： 帮忙为AMY和Mavis购买角膜塑形镜的护理液, 很抱歉紧急联系，AMY和Mavis的角膜塑形镜的护理液用完了，她们不戴眼镜就看不到任何东西，是否可以请学校员工帮忙购买？可以是任何品牌的（比如： Boston、Menicon），只要能用。关于费用的支付方式也请告知！谢谢！

Subject: Urgent Request for Purchase of Contact Lens Solution for AMY and Mavis

Dear Summer School Staff,

I hope this email finds you well. I am writing to you with an urgent request on behalf of AMY and Mavis.

Unfortunately, they have run out of their contact lens solution, which is essential for their corneal reshaping lenses. Without these lenses, they are unable to see clearly. I was wondering if it would be possible for a member of the school staff to assist in purchasing more solution for them?

They are not particular about the brand of the solution and are open to any that are available, such as Boston or Menicon, as long as it is suitable for their lenses.

Could you also please inform us about the payment method for this purchase?

Thank you very much for your attention to this matter. We appreciate your assistance and look forward to your prompt response.

Best regards, [Your Name]
