I have just ordered some Glasses from Goggles4u as they are £4.99 for a complete pair.
I found that if I added a photocromatic lens they offered glass photocromatic lens for only £14 more and I only need buy this one pair to get free delivery.
This includes all the coatings that other sites charge for such as UV, anti refective and scratch resistant.
Being glass they will be about twice the weight of plastic but glass does react quicker and for the price you can't do better. (If you want plastic lens they are £33)
There seems to be some issues on delivery time as it can take up to 3 weeks to arrive. This is aproblem with some people but overall the feedback is good & I feel it is worth the wait.
The total is £18.99 but if you use the code GlassyEyes they come down by 10% to only £17.10 including delivery.
Glasses ordered on 26th April arrived today 6th May (10 days). They are brilliant and the photcromatic lens are great. The prescription is perfect.
I made a mistake when ordering so I used their web chat and and they upgraded my frames from a £4.99 pair to a £15.99 pair for free so a thumbs up for customer service. In addition the pair I recieved have been upgraded to a plastic photochromatic lens with out my asking so I'm doubly happy.
Having read some Hot Deal members reports, it seems there are some who have had a problem with this company but my experience has been 100% recommendable.
For £17.10 for prescription photochromatics you really can't go wrong.
