Thin & Light Lenses
A cleaner, lighter finish for stronger prescriptions. Choose from standard, thin, extra thin and ultra thin lenses — fitted and checked by a UK Registered Dispensing Optician.
Designed for a neater finish
Lens thickness can make a noticeable difference to the overall look and feel of your glasses, especially with stronger prescriptions.
A thinner lens can reduce edge thickness, improve comfort and help the frame sit more elegantly on the face.
Choose your lens thickness
Your lens index is selected based on your prescription, frame choice and the finish you prefer.
1.5

Thin & Light lenses. A neater option for moderate prescriptions.

Extra Thin lenses. Recommended for stronger prescriptions where appearance matters.

Which index do I need?
You do not need to guess. Once your prescription is received, your lenses are checked against your frame choice to make sure the most suitable option is selected.
