Is the problem with seeing an eclipse that you have a sudden change between penumbra and regular sun? If that's the case, why can I look to the sun with my sunglasses on but I can't do it in an eclipse because it would be harmful? Even if my sunglasses have an UV filter it would be bad for my eyes to see the eclipse with them?
