Hi Barry. Thanks for reminding me, I have been wearing them now for a few days and these are my impressions. I’ve already commented on their construction and durability, so lets move on to practicality. I have the tinted lenses model which is quite effective at stopping bright sunlight from hurting my eyes, though not entirely as they aren’t wrap around. The sensitivity I feel is a little over sensitive particularly in busy environments such as shopping centres and markets etc. because there are plenty of moving obstacles IE people which makes gaging distances very difficult. This isn’t the glasses fault as its the way they’re designed, but its more of a hindrance than a help and I find myself turning them off when in such places as their effectiveness is pretty much useless in that sort of situation. Having said that, when walking along a busy street or even a quiet one, I’ve found them to be particularly good especially with overhanging trees, bushes and the like. I use a guide dog so he does work around these obstacles quite well unless he’s inclined to go and have a sniff, but as a rule the performance is very reasonable and you get plenty of notification via the vibration’s increasing frequency of an upcoming obstacle. All I would ask is that in a future model of these, you could have optionally audible feedback rather than vibratory and that the sensitivity of the sonar could be adjustable. However, having said that, for 80 quid they’re not at all a bad investment. I hope this helps you barry and any one else considering these, they do come highly recommended by me.

I’ve just taken delivery of my RNIB sonic eye glasses, and first impressions are good. They feel sleek and are solidly built, and although they’re made of plastic, they’re rugged and durable not to mention quite comfortable. They have both audio and vibratory feedback and are charged via USB either via plugging the supplied cable in to a USB port on your PC or in to the supplied travel adaptor. If anyone wants to know more about them, I’d be happy to answer any specific questions, but my general impression and probably a lasting one is that RNIB have yet again come up with a very useful product at a fare price, certainly within the affordability range of most if not all persons who feel they could use a sonic aid but who might be put off by the pricier alternatives. All the best, Ibrahim. __________ Information from ESET Smart Security, version of virus signature database 5999 (20110330) __________ The message was checked by ESET Smart Security. http://www.eset.com
