A

About ten men in every hundred suffer from colour blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!

  There are different forms of colour blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green―a strange world indeed.

Colour blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in a bright light and to tell difference between colours. There are also millions of "rods"? but these are used for seeing when it is near dark. They show us shape but no colour.

Some insects have favourite colours. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favourite colours. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colours by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colours around us.

Barbara Klein : Our VGA listener's question this week comes from Bangladesh. Murnna asks if Hawaii is an American state.

Experts believe that Polynesian people discovered the Hawaiian Islands about two thousand years ago. A king ruled the islands when British sea captain James Cook arrived in 1775.

In 1818, the Hawaiian King Kamehamcha said the group should be called the "Islands of the Kingdom of Hawaii".Britaingave the islands their independence in 1843. The king was ousted fifty years later by a group of American businessmen. Hawaii became the fiftieth state of theUnited Statesin 1959.

The state of Hawaii includes eight major islands in the middle of the North  Pacific Ocean. The main islands are Kauai, Oahu, Molokai, Maui, Lanai and Hawaii, also called the Big Island. The island of Niihau is privately owned. Kahoolaw has no people.

Hawaii is far from other populated areas. It is more than three thousand kilometres from the state of Califor?nia. It is more than six thousand kilometres fromJapan.

Hot liquid rock called lava formed the Hawaiian Islands millions of years ago. The lava flowed up from the sea through openings in the sea floor. Visitors today can watch this process continue on the Big  Island where the world's most active volcano still produces lava.

Each of the Hawaiian  Islands has a wet side and a dry side. It rains much more on the north-east sides of the islands and much more in winter than in summer. This gives each island two separate climate areas. One area is dry and desert-like. The other area has green plants, rivers and waterfalls.

More than six million people visit Hawaii each year. They enjoy the beautiful land and the warm weath?er. They swim, watch the whales and other marine life and visit beautiful gardens. Hawaii has some of the most beautiful, interesting and unusual places on the earth.
