Problems with new glasses

tpotx

Hi, I have been wearing contact lenses for around four years but I've been suffering particularly badly from hayfeaver this year so decided to purchase glasses to use over the summer.
I went to specsavers to order some, chose the frames and was advised to have the lenses thinned due to the high prescription as they would look better cosmetically. I received the glasses Sat but couldn't get used to them as unless I am looking directly through the middle everything has an orange or blue haze around it (think resady brek ad). I've been back today and been told that this can happen with thinned lenses (wasn't told this at the consulation) and that I need to see the dispensing optomotrist tomorrow to discuss different lenses.
Does anyone know where I stand if there is extra cost to this or to get a refund if there is no solution, as if I had known the risk of distorted vision I definatly would not of gone for the thin lenses.

It is called chromatic aberration and is caused because the lens is further away from the eye at the edges. It doesn't happen with contacts as they are on the eye. The higher the prescription, the more noticeable the effect.
It is also much more noticeable because you have been wearing contacts for ages.
It will happen with standard lenses too, just less noticeably than with thinned down lenses.

Basically it is down to how you prefer them to look - it is something you will need to accept if you want thinner lenses.

Specsavers are franchises so depends on each one as to whether you get a refund or not but in 99% of cases they offer and stand by a no-quibble guarantee so you should be ok if you change.

I have always had thinned down lenses, but never had this kind of problem, not noticeably.

This could be because you have a weaker prescription, because you have small frames (the larger the frame the more the aberration), or because you are more tolerant optically-speaking.

I have thinned lenses myself and you soon become adjusted to it - although harder to do so if you swap between contacts and specs.

The first time I had them it was awful but now it is barely noticeable.

OP, get Specsavers to check the optical centres of the lenses are positioned correctly then at least you will have no problem when looking straight ahead.

Also - are they coated with a mulitcoat/anti-reflective coating?

Hi, thanks for the replies, I don't think they have been coated as there is no mention of it on the receipt - my prescription is R -7.25, -1.00, 165.0 L -8.50, -0.50, 10.0.
I don't think they are centred correctly as they were slanted (also a reason I went back today) they had to adjust them twice and they still arn't right. They are rectangular half rimmed ones and it says on the receipt thinned to UCLR 1.67AS SV
Maybe I'd be better sticking with the contacts. I did tell them how long i'd worn contacts so if they had explained the posibility of this distortion I wouldn't of got them.
