My absolute favorite episode of The Twilight Zone is one in which a book loving nebuch finds that he may be the sole survivor of a powerful bombing and that he has all the time to read that he wants — but loses it all when his prescription glasses are shattered in an accident. I wondered how it was possible that he couldn’t find a suitable replacement but I imagine it might be difficult to find anything if your glasses are broken. An English company may have solved this issue with their innovative glasses which are adjustable by the wearer such that the prescription of the glasses match his or her eyes.
The idea, it seems, was for the benefit of people in remote areas who do not have the best access to eye doctors and don’t live within walking distance of dozens of eyeglass shops as those in major cities do. The person could get the glasses and put them on and adjust them until proper vision is found, so to speak.
I see this as beneficial for struggling families regardless of location. A family comprised of people who only need multiple pairs of glasses due to different prescriptions could get one or two of these instead and share them — it would work equally well for all. Even if they all had to get their own individual pairs of glasses, it would still be considerably cheaper in the long run for the family as there would not be a year to year consideration of changes to each family member’s prescription. Instead of having to get new glasses every year or two, the glasses can just be changed to the needs of the user.
Of course, there is one down side as I see it and that is that people’s perception of what is good for their eyes is not ever going to be as accurate as an eye doctor. When I took an eye exam the doctor had me judging if I saw better with one lens or another after another. While they all looked mostly the same to me, only my doctor had the understanding that one of the lenses was best for my vision and the rest were not as good. I suppose it would work well enough for people with little or no access to an eye doctor, however — close is better than nothing, right?
