- high index lenses
I got some new glasses about a year ago and had high index lenses put in as my prescription is minus 6.5.Posted 4 years ago
Anyway, they made me feel really dizzy and after a few days it was no better. The optician told me that some people don’t tolerate high index lenses, so they made me some new ones with a lower index, which were fine.the hustlerMember
you ‘might’ be noticing an effect called ‘power rings’ hopefully it will settle although some people cant tolerate it. This could be compounded if the lenses have been bevelled (basically has the edge of lens been ground off), if its a machine bevel sometimes they can be a bit big on your power of lens, a well done ‘hand’ bevel can look much neater and be less noticablePosted 4 years agoT666DOMSubscriber
The 1.67 may be aspheric, which would alter your peripheral vision slightly. Higher index lenses generally disperse the light more as the index increases, causing more chromatic abberation, especially a problem with high minus lenses.
PD’s might be out so you’re not looking through the centre of the lens, or the centres may be correct, but the old 1.6 might have been wrong which your eyes have adapted to. This would make the new spex hard to get used to.
Prescription may be wrong or glazed incorrectly.
Go back to the optom who supplied them and explain what’s going on.Posted 4 years ago
