There's no great need to get a Class 1 earlier than necessary.
If you intend to go on to a flying career, then it would be an idea to ask the AME assessing you for the Class 2 if he thinks there would be any issues with you obtaining Class 1 with eyesight, hearing etc.
You could get a Class 1 now and use it for Class 2 privileges. At least you would have the initial issue out of the way and confirmed that there are no issues, but it is a significant expense that can be deferred until required.
