I'm also not sure about 'accomodating' lenses, and their legality.
I've tried multifocal specs before, and they were a PITA
. These specs had various zones with different correction. So, you could look straight ahead through the part of the glass which corrected for distance, or look down and find yourself looking through a bit of the same glass which had a correction for reading. Ive seen ones which blended the areas of diffeent correction, and others that had sharply defined boundaries. Anyway, no likey.
The 'multifocal' intraocular lenses that 'my chum' is looking at have only one area of correction. There is no 'zone for reading' and 'zone for distance'.
Instead the offer seems to be that the artificial lens actually refocuses as you change from looking at distance, to say, reading.
This seems implausible to me as the new artificial lens would need somehow to physically change shape in response to the direction of ones gaze.
Can this be true?
They promise correction for distance, and no need for reading glasses.
Sounds too good to be true! Anybody got these???
