The clear picture on glass

What makes it appealing

A hard, scratch-resistant surface and excellent optical performance. Scratch-resistant does not mean scratch-proof.

What to consider

Glass is generally heavier and less impact-resistant than plastic. It can chip or break and is generally unsuitable for sports, children’s eyewear or situations needing impact protection.

Will these lenses suit my frames?

Frame condition, construction, size and prescription affect suitability. Please ask our team if you are unsure. Do not assume that rimless or semi-rimless frames are suitable for glass lenses.

Your prescription and measurements

Follow your order instructions to provide your eyeglass prescription and any required measurements. If you need to send them separately, email contact@drlenschange.com with your order number. Production requires complete information.

Coatings and lens specifications

These bifocal and trifocal options are uncoated. Do not assume that other coatings or UV-protection specifications apply to every option.
