I just got my new zenni order, and once again, they did great, for cheap. Threee pairs of glasses (two progressive and one single-vision) for $102.45 including shipping. Last time I bought locally, I paid close to $600 for one pair.
I KNOW that my vision changes during the day, and I'm sure that my prescription isn't as "perfect" as it could be. I'd also like to customize my prescription for my various workstations. I know that can be done with math and a ruler, but I'd really like to be able to zero it in as close as possible. There was someone who posted here a while back that they had purchased a set of trial lenses and made their own prescriptions. I'm thinking I could do the same. Trial lens sets are about $200 on ebay
There is this set for $225 with 158 pieces:
OR, there is this set with 232 pieces but in plastic rims for $225
Is there anything wrong with using the plastic rims (remember I'm only going to use these a few times a year), or are the metal rims way better (that's the metal content to keep on-topic) ?
Does it make sense to buy the larger set?
If I do this for myself and for my wife a couple of times, the cost of the lenses will be covered by what we would have paid at the eye doctor in insurance copays. I'm thinking that with our current prescriptions to get into the ball park, I ought to be able to dial it in better than the doctor did. Is this a truly goofy idea, or am I likely to be successful in getting a better prescription?
