05 Jun 07 - 03:47 AM (#2068844) Subject: Tech: Failing Eyesight From: ThreeSheds My father is having problems with glaucoma and is having real problems with blind spots and the tunnel vision effect, as a result using the computer is often a very frustrating experiance. Obviously there is no solution to this,but I wonder what practical advice is out there from catters who might have or have knowledge of a similar experiance |

05 Jun 07 - 09:47 AM (#2069062) Subject: RE: Tech: Failing Eyesight From: mack/misophist 800x600 screen resolution should help. There are on screen magnifier programs available but I don't like them. As stupid as this may sound, giving the screen a good cleaning may help also. |

05 Jun 07 - 09:57 AM (#2069067) Subject: RE: Tech: Failing Eyesight From: Bernard Another seemingly daft suggestion... try a bigger screen! These days, 19" TFT monitors are quite cheap - but beware of the small print! You may end up with a 19" Widescreen TFT, which is really a 15" 4x3 stretched sideways, so to speak! A 21" CRT would be quite cheap secondhand, and the visible screen area is about the same as a 19" TFT. The snag is the overall size... an enormous great lump! Maybe a video card with a TV output - assuming you've a big TV? There are settings to change the screen appearance, which may help. The standard XP screen colours aren't contrasted as much as other settings - play around with Display Settings - Appearance, until you find something that works better. |

05 Jun 07 - 10:02 AM (#2069077) Subject: RE: Tech: Failing Eyesight From: GUEST,Tom K If your father is a veteran and is ever declared legally blind let him know that Veterans Hospitals have blind rehab programs that address all aspects of vision loss as well as a computer access training program (CAT) that uses either large print or voice systems as is needed. It's unfortunatly a little known but highly regarded program in the VA system. If you or anyone else wants more info let me know. Tom |

05 Jun 07 - 12:54 PM (#2069220) Subject: RE: Tech: Failing Eyesight From: ThreeSheds Thanks for all the suggestions, its really tricky to understand the problem, for example the bigger screen idea sounds promising but with the tunnel vision it would just give a bigger area to loose the cursor in. I had wondered whether he ought to rely less on the mouse ie use more keyboard commands,the obvious one was to use return when an option is highlighted rather than trying to position the mouse on it,but the highlighted option is only subtly highlighted, and not apparent to him |

05 Jun 07 - 08:17 PM (#2069586) Subject: RE: Tech: Failing Eyesight From: mack/misophist You can always change the cursor, especially the size. In linux (hint) there's quite a selection at kde-look.org. |

05 Jun 07 - 10:50 PM (#2069670) Subject: RE: Tech: Failing Eyesight From: The Fooles Troupe You can have animated cursors in Windoze - this may catch the eye quicker rather than a normal cursor. |

06 Jun 07 - 06:39 AM (#2069834) Subject: RE: Tech: Failing Eyesight From: Bernard With most meeces you can change a setting so that pressing, say, the Ctrl key on its own causes a ripple of circles (or some such) to appear around the cursor, making it easier to find. |

07 Jun 07 - 10:46 AM (#2070743) Subject: RE: Tech: Failing Eyesight From: GUEST,Al no cookie Three, I offer this suggestion as a doctor who treats a lot of glaucoma patients. Since your dad has significant loss of peripheral vision, making things bigger might only make things worse for him because there would be less visual information in his remaining field of vision. It might actually help him if you were to increase the screen resolution, which would make things smaller. Providing he has good enough visual acuity (at or near 20/20), he might do better this way because there would be more information within his remaining field. I know this is counter-intuitive, but you might give it a try. I also really like the ripply cursor idea. If you have any other specific questions regarding glaucoma, feel free to PM me. Al |
