Go to a store where you can buy the square dark lenses that fit into a welder’s helmet.

This will allow you to view the Sun with no problems but seeing Venus traverse the face will be like trying to view a grain of sand traversing the face of a light bulb at 20 feet.

More like a small fly very slowly passing in front of a bulb.

These transits are definitely visible to a good naked eye. Just use some very dark shades.
