How the Blue Light Lenses Work
The lenses carry a subtle blue light filtering layer that trims the harsh blue light emitted by phones, tablets and computer screens. Softened screen light means less visual fatigue during long study or work sessions, while the clear base tint keeps colours looking natural indoors. Prescription strengths from -0.50 to -4.00 are built into every lens.

Frequently Asked Questions
Are these prescription glasses?
Yes — the lenses come ready with myopia (nearsighted) strengths from -0.50 to -4.00. Select your strength from the options above.
Do they block all blue light?
They filter a portion of the blue light from digital screens to reduce eye strain. They are not medical devices and do not treat any eye condition.
How do I choose my strength?
Use your current glasses prescription. If you are between strengths, the lower one is usually the more comfortable starting point for screen use.
Do they come with a case?
Yes, every pair ships with a protective case and cleaning cloth.
Common questions
What prescription range is available?
Lenses are offered in -0.50 to -6.00 diopters. Choose the value that matches your current distance prescription, and step up only if signs across the room still look soft.
Can I use these for driving?
They are distance lenses made for nearsighted wearers, so road signs and traffic lights read clearly at range. Always follow local licensing rules for vision and have your eyes checked regularly.
Which colours can I order?
3 colourways are available: Black, Rose Gold, Silver. All colourways share the same lens specification, so the choice is purely about how the frame looks on you.
Is the Metal frame comfortable for all-day wear?
The metal frame keeps total weight low, and the nose pads sit flat instead of pinching. Wearers who spend hours at a screen or in a book usually notice the difference on the bridge of the nose first.
Does Rongchy ship free, and what about returns?
Every order ships free worldwide with tracked delivery and no minimum spend. If the fit or the strength is not right, you can return the pair within 30 days of delivery for a refund or exchange.
