Today's demand is that I phone the 'so called' optician to see if he can go back to wearing contact lenses. This is the 4th optician in 4 years. They have all explained, as has the ophthalmologist, that the problem is the signal between his eyes and his brain is not working. He told me that he had contact lenses up to lockdown - it was about 25 years since. Plus he can't even put his own hearing aids in. Do I waste the opticians time? Do I waste money on something he won't be able to use? The trouble is that although his memory is terrible, once he fixates on something like this, he won't forget. So far we have a stack of glasses that 'don't work', dentures that 'don't fit' and hearing aids that 'must have been mixed up with someone else's'.
