Blue Light can be seen almost everywhere. Exposure to blue light from ambient sunlight, computer screens, tablets, and mobile phones is constantly received. The brain links blue light as daytime, so when exposed to this kind of radiation at night, it makes it difficult to sleep.

This lens from Majestic helps to filter blue light and reducing the occurrence of eye strain. For someone who spends a lot of time on screens at night, blue light filtering lenses, IS the recommended option. Ask you optometrist.

Majestic Blue Light Cut filters up to 420nm of the visible spectrum without altering the perception of color. For this reason, we assure this is also one of the best lens options when it comes to prevent the damaging effects of UV rays.

Did you know the harmful effects of Blue Light?

These include short term effects such as fatigue, visual stress, blurred vision, insomnia, and dry eye, among others. Blue light reaches all the way to the retina which and damages light sensitive cells found in this part of the eye.

This puts your patient/customer at risk for long term effects such as (AMD) Age-related macular degeneration, a common symptom among older adults, which is accumulative and irreversible. The use of digital devices accelerates and magnifies this damaging effect.

 What are the benefits of Blue-Turquoise Light?

Blue Light Cut permits the passage of Blue-Turquoise light rays that are beneficial for overall health, regulate healthy sleep patterns, improve cognitive performance, and control our pupillary reflex.

How does Blue Light Cut work?

Majestic Blue Light Cut lenses are composed of a monomer that blocks Blue light and Ultraviolet light (HEV). Since the particles that block these damaging rays are contained within the mass of the monomer, the lens never loses these beneficial filtering properties. This is, in contrast to a superficial coating treatment applied to the lens which could suffer from scratching of peeling of the coating
