Färgblindhet Alla människor uppfattar inte färger likadant. Människor som har ett avvikande färgseende kallas färgblinda. Total färgblindhet är mycket ovanligt. Det finns många olika typer av färgblindhet. Den vanligaste är röd-grön-färgblindheten, som är mycket vanlig hos män. Färgblindhet är nästan alltid medfödd. Så här fungerar det Då vi tittar på ett föremål kommer ljus in i ögat. Tappar och stavarDet finns två typer av synceller på näthinnan. Ljus av olika färg har olika våglängd. Uppfattar färger annorlundaRöd-grönfärgblinda kan inte se skillnad på rött och grönt, och vissa andra färger bereder också svårigheter. Varför är män oftare färgblinda än kvinnor? Därför att färgblindhet är ärftligt och genen som ger färgblindheten sitter på X-kromosomen.Dessutom krävs att genen är recessiv, och så är det med färgblindhet. X- och Y-kromosomerna bestämmer en persons kön. Hos män finns bara en X-kromosom, så om den har en gen för färgblindhet så blir mannen färgblind.
Blinda fläcken Most people (even many who work on the brain) assume that what you see is pretty much what your eye sees and reports to your brain. In fact, your brain adds very substantially to the report it gets from your eye, so that a lot of what you see is actually "made up" by the brain. Some special features of the anatomy of the eyeball make it possible to demonstrate this to yourself. The front of the eye acts like a camera lens, differently directing light rays from each point in space so as to create on the back of the eye a picture of the world. The picture falls on a sheet of photoreceptors (red in the diagram), specialized brain cells (neurons) which are excited by light. The sheet of photoreceptors is much like a sheet of film at the back of a camera. Look around. Close your left eye and stare at the cross mark in the diagram with your right eye. So, as you can see, you have a pretty big blind spot, at least as big as the spot in the diagram. Resources Elsewhere:
