Hopefully one of our answers below will have you covered. If we’re missing an answer, please contact us using the contact form.

What are your lenses like?

All lenses are custom made by our glazing house in Cardiff (UK). We offer a range of different indexes (thicknesses) to suit your needs. From 1.5 (standard) to 1.67 (super thin), all of which are included as standard in our prices.

Our glazing technicians are experts at choosing the best lens type for your prescription and chosen frame.

All lenses come with anti-reflection (MAR), anti-scratch coatings and UV protection at no additional cost to you.

Sun lenses have a sunlight filter of 3, offering excellent protection from the sun and perfectly suited for general purpose.

What if I have a high prescription?

No problem. In most cases, we’ll be able to help you out.
We can produce prescription lenses with a sphere (SPH) up to -10.00 or +10.00 and a cylinder up to -6.00 or +6.00. Please submit your details and we will contact you with options. On occasions there might be a small extra charge for more complex prescriptions.

Prescriptions with powers higher than -4.00 or  +4.00 can only be ordered if your PD is given (pupillary distance).

What if I don’t know my PD?

Your PD (pupilary distance), is simply the distance between your pupils. This measurement is always taken by your optician and helps place the focal point correctly in front of your eyes in custom lenses.

Before submitting your prescription details, you can ask your opticians to provide you with this measurement.

In general the PD for most adults is betwen 54mm-74mm. For standard prescriptions under +4.00 and -4.00 we can glaze an average of 62mm if the PD is unknown.

The PD number must be know for more complex prescriptions and for prescriptions over +4.00 and -4.00.

Can I get a rush service?

Yes of course. We can provide a 1 week rush service for an extra fee of £20 (may exclude very high or complex prescriptions).

My new glasses don’t seem right. What should I do?

If you’ve worn glasses before, you’ll know it can take up to two weeks for your eyes to adjust to your new lenses, this could be because your prescription has changed a little, the new frame sits in a different position to your last, or you’ve been looking through scratched lenses for too long. This is fairly normal. However if you think you are experiencing more than regular issues, please contact us straight away.

Do not continue to wear glasses that cause severe blurriness or discomfort.

How do I find the right frame for me?

What matters most is how you feel in your glasses. Read our face shape guide to help match the right shape with your face. Or, you can use our virtual try-on tool or our postal try-on service.

The basic rules to follow:

• Your glasses should sit comfortably on your nose
• Your pupils should look through the middle of the lens
• The lenses shouldn’t be much wider than your face

Need more help? We’re always here to support and can offer recommendations on frames and lenses. Just send us a photo and we’ll help match you with the right Birds.

Can I have polarised prescription sunglasses?

In most cases, sunglasses without polarised lenses are perfect for everyday life. However, if needed we can add an a polarising layer for an extra £30 – please add a note with your submission and we’ll send you a payment link.
