Frequently asked questions (FAQ)

WILL THESE GLASSES HELP ME TO PASS THE COLOUR BLIND TEST?

forward arrow
Over 85% of Pilestone customers have found our glasses helpful.

If the lens type is the right one for you, then an improvement in the score is expected. Lighting conditions and PC/phone screen colours may affect results.

A better way to evaluate the effectiveness of Pilestone glasses is to go outside and explore the world. Correctly naming the colours you see is the best indicator that the glasses are optimally performing.

Please do not wear our glasses to drive until you are sure the glasses are working well.

IS THE PILESTONE LENS POLARISED?

forward arrow
Pilestone lenses are not polarised but outdoor lenses are titanium coated to protect against glare and equipped with full UV protection, meaning your eyes will be safely protected from the harmful rays of the sun while being able to see the world in a whole new light. Colourblind glasses already have tints and Polarisation will make the glasses darker and harder to see through.

CAN YOUR GLASSES BE MADE WITH PRESCRIPTION LENSES?

forward arrow
Yes, you can add a single vision prescription or progressive lens prescription to your new colour blind glasses! After completing your purchase, please email to katie@pilestone.africa with your order number and prescription details.

Prescription colour blind glasses are non-refundable. If you have not yet tried Pilestone colour blind glasses we recommend to order a pair without prescription first to test and make sure they are right for you. Please allow 2-4 weeks for delivery of prescription colour blind glasses.
