Your squirrels are adorable!
Love those ears!
Thanks for taking care of them and trying to help.
If you can buy some unsalted nuts (walnuts, pecans, hazelnuts, almonds) and give them some slices of ripe avocado (no pit or skin) that would be much healthier than seeds, peanuts, and bread. Peanuts are not recommended for a variety of reasons. They might even like a bit of cauliflower, broccoli, apple, etc.
Here's a chart you might find useful:

The chart says "pet squirrels", but it's a good general guide for squirrel nutrition. Wild squirrels can eat more nuts than those in captivity because they know how to balance their diets and are not solely dependent on humans for food.
Hope that eye continues to improve!
