About Us

Where are you based?
We are based in Watford in Hertfordshire in the UK.
Are you qualified Opticians?
Of our three directors, one is a qualified optometrist; one is a qualified dispensing optician and the other is a qualified ophthalmic optical technician and all our staff are optically trained and experienced. Using all this knowledge we are able to provide a professional, well advised service to our customers whilst still keeping our prices as cheap as possible. However, we do not do eyetests. If you require an eye test you should visit your local optician.


Our Products

How do you provide prescription glasses at such low cost?
Our glasses may seem cheap compared to the high street but this is not because our quality is poor. In fact quite the opposite. You will find exactly the same frames stocked in 1000's of opticians across the country. It is because we do not have the expensive overheads that high street opticians have in order to run their business. Expensive premises and customer facing staff all add to the cost of the product. All of the cost savings that we make are passed on to our customers.
Do you sell sunglasses?
Yes. We have a range of sunglass options including Polarised, Light Sensitive and Sunglass tints. All our Sunglasses have the tint and full UV protection included in the price. If you order a sunglass tint on any clear lens frame we strongly recommend a UV400 (Ultra Violet Ray Blocker) for an extra £19. This is recommended since with a standard tint alone there is no protection from the sun’s rays.
Are your lenses made of glass or plastic?
Our lenses are all made of plastic. We do not manufacture glass lenses. Plastic lenses have the benefit of being light weight and safer since they do not shatter on impact.
Do you sell brand names/designer labels?
Yes – and at a fraction of the high street prices.
Do you offer trial frames?
Yes - we are happy to organise a trial of any frame you would like to try on (terms and conditions apply).
Are your frames CE Marked?
All of our frames are CE Marked and quality checked by our frames suppliers.

About Prescriptions

I can't read my prescription. What do I do?
If you cannot read your prescription you should verify it with your optician. If you wish our customer services team to look at it you can email a scanned copy to If we cannot read or understand it you may need to ask your optician for a duplicate copy.
There is no 'Sphere' value on my prescription
If you have an Astigmatism (this means your eye is not a perfect sphere and is very common) but otherwise normal vision, there may be no value under the sphere column. Similarly you may only require spectacles for reading - in cases like this there may also be no sphere value.
I have no Cyl or Axis Value on my prescription
If you have a 'Cyl' value on either eye, you will always have an axis value. If you do not have this then please call your optician to verify your prescription or fax your prescription to us on 01923 710175 - 01923 710175 or email
There is no PD value on my prescription
This is very common and you have a number of options:
  • Go to your optician and ask him / her to measure your PD value for your prescription
  • Ask someone else (friend / family) to measure it for you, following these instructions
  • Accept the standard average for both male (63) and female (60) that we have indicated on our order form. These have been agreed with our dispensing opticians as being average numbers to choose, however you will receive more effective glasses if you measure this accurately for yourself.
What is my Pupillary Distance?
Your Pupillary Distance is the distance in millimetres from the centre of the pupil in your left eye to the centre of your pupil in your right eye. An average man is 63mm and ladies 60mm.
Why do you need a 'Pupillary Distance' measurement?
We need this measurement in order manufacture the lenses so that the centre of each lens sits exactly over the centre of your pupil. This allows for maximum effectiveness when wearing your prescription glasses.
How do I measure my Pupillary Distance?
See our detailed section on measuring your Pupillary Distance.
What about my Bifocal measurements?
Our bifocal lenses are manufactured with 'Dseg' (D28) bifocal lenses rather than round lenses. The bifocal lens sits 3mm below the optical centre of the base lens. It is assumed that you wear your glasses approximately 13 - 14mm from the eye.
Can you help me with the prescription details?
The prescription page of our website contains very clear information on how to enter prescription information. However if you do need help please call our customer services team on 08000 289 550 - 08000 289 550. If we are busy please leave a message and someone will return your call.
Where can I get a prescription?
You can get your prescription from your optician. If you have had an eye test within the last 2 years you need to go to the optician who carried out the test. Ask them for a copy of your prescription. Opticians are legally obliged to provide you with this. If you are going along for an eye test always ask to be provided with the prescription before you leave. Do not feel pressured to buy your glasses from the optician who conducted your eye test. Alternatively phone your optician and request a copy of it to be sent to you.
What if I enter my details incorrectly?
If you enter you details incorrectly then you need to call us immediately in order that we can change the prescription before we go to assembly, it is important that you do this since lenses in the manufacturing process cannot be refunded or changed.
Can I change my prescription details after I have ordered?
Once we begin manufacturing the lenses we cannot accept a change of prescription. If you realise that your prescription information was entered incorrectly, you need to call us immediately on 08000 289 550 - 08000 289 550. We will inform you if you have the possibility to make a change at that time.
