Can you look at a solar eclipse with bare eyes? I hear its bad and could burn your eyes. So what could you use to look at one?

No.
Safe filters:
1. Eclipse shades (from telescope stores and astronomy clubs)
2. #14 welder's glass (from welding supply stores
3. Pinhole camera: punch a small hole in a piece of cardboard and put it in a west northwest facing window.
Nothing else is safe, no matter what you may read!

No. There are special filters made for that but do not assume any filter will work; it must be labeled as safe for viewing the Sun. Do not risk using an unknown filter.
The safest and easiest way to view is pinhole projection. Use a toothpick to poke a small hole in a piece of paper. Then hold another piece of paper behind the one with the hole so it is in the shade of the one with the hole and you can see a little dot of light where the Sun shines through the hole. Now move the sheets of paper farther apart. As they get farther apart the little dot of light will get bigger but dimmer. When the papers are arm's length apart, say 3 to 5 feet, the little dot should be a quarter inch or so big but still bright enough to see easily. That is actually an image of the Sun. With no eclipse it is just round and might fool you into thinking it is just a blob of light. But with a partial eclipse you will see the bite taken out of the Sun by the Moon.

Yes you can, but it would badly damage your eyes.

Special film filters in eclipse glasses might be safe enough.
Better is a pinhole camera--empty box with tiny hole in one end, and white paper at other, project sun image to see the annular eclipse safely.

No you should not look directly at a solar eclipse. It will damage your eyes.
You need to look through a filter or a reflected image.

No, I have heard it can cause blindness in a few minutes, welders visor might work, or watch the moons shadow cross the earth on dish earth channel.

It's very bad for your eyes. There are some special fillters you can use
