The system aligns with benefits centred on screen protection, visual comfort, and everyday usability in modern, screen-heavy settings.

Why Ra Optics is Healf
Tempest Daylight - Mountain Forest uses daylight lenses that selectively filter harmful blue light while preserving beneficial wavelengths, addressing the strain caused by modern LED and screen exposure. This approach helps reduce digital eye strain, headaches, and fatigue without blocking light your body still needs during the day. By supporting healthier light input, the lenses help stabilise stress hormones and protect cells from ongoing light-related stress. The result feels more balanced and natural than simply dimming or darkening your view. Energy levels and mental performance stay steadier across long screen sessions.

Ra Optics was founded by Matt Maruca after his own health journey led him to uncover the effects of artificial light on circadian biology. His mission became clear: to create the world’s highest-quality blue-light-blocking eyewear, backed by peer-reviewed science and guided by ancestral principles. Crafted with proprietary lens technology, Ra Optics glasses are engineered to protect mitochondrial function, regulate melatonin production, and reduce the impact of screen-induced fatigue. It’s a deceptively simple tool, designed to restore one of the body’s most critical rhythms—light and darkness.

With our Healf Curation Process, we do the work for you. Shop with confidence knowing that every item has been tried, tested, and curated for you.

The best wellbeing website…

The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Alex

Amazing!

Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Janet

Great products, service, and customer support

Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf

It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
