Our Lens fitting Service - How it works

Prescription lenses for glasses online

I've bought a frame on it's own without lenses. But now I'd like you to glaze it for me.

This isn't a problem for us at all, add a lens package to your basket and we'll send you a mailing bag, prescription form with all the necessary postage to send your frame off to our lens lab for glazing.

How do I know if I have the right SPH for High Index lenses?

Your SPH will be either or above + or - 4.00
Example of a Prescription that would fit under a "High Index" package:High index prescription lenses for glasses online If your SPH falls between the strengths shaded in blue above on our prescription strength chart you are covered by our "High Index" package. If your SPH is less than this we recommend our "Standard Lenses" package which can be ordered here. However, if you have a low SPH and a very high CYL you will still need High Index Lenses. 

I have a value under CYL in my prescription, does this affect my Lenses?

Not everyone will have a value under the CYL section of the prescription form. But if you do this means you have astigmatism, the value simply tells us the severity of that astigmatism. If your CYL is over + or - 2.25 we recommend that you purchase High Index lenses.High index lenses for prescription glasses online This is shown in blue on the prescription strength chart above, indicating the strength values which can be included under High Index. However, you may have a very low CYL but high SPH this still means you require High Index lenses.

What if only one of my lens values are classed as "High Index"?

We class them as a pair. So if you have a SPH for one eye over +/- 4.00 both lenses will be High index. The same for CYL, if you have a high CYL in one eye both lenses will be classed under "High Index".
