We don't offer blue-light filter coatings at the moment. There is quite a lot of debate in the optical industry as to whether these actually do any medical good or not. They also have the added downside of not looking very attractive, often having a very bright blue reflection. Research is still ongoing however, so it is something we may consider in the future if we feel it would benefit our customers!
A fantastic alternative is downloading blue-filtering apps for your digital devices. These are free and this way you can enjoy the benefits of the coating but without any obvious blue reflections in your lenses or having to see everything in a yellow/sepia tone.
All of our glasses do come with a regular antireflective coating as standard which still does prevent eyestrain by allowing more light in to your eye than an uncoated lens. This makes computer use more comfortable and makes a huge difference when driving at night. This coating also has the added bonus of looking much more subtle!
