Lenses for sunglasses and plano
Your favourite sunglasses have the perfect frame. The problem is the lenses: scratched, with the mirror flaking off, or you simply want a fresh finish. There's no need to buy new glasses.
We replace the lenses in your sunglasses and return them like new. We work with high-quality CR39 organic lenses, Elite polarised, photochromic and plain (non-prescription) ones, compatible with the market's leading brands. If you wish, add your prescription and turn them into prescription sunglasses.
Available lens types
From standard organic to HD polarised, choose the finish that best fits your use.
| Type | Description | For whom |
|---|---|---|
| Standard organic CR39 | High-quality plastic lens with UV400 Cat. 3 | Daily use, beach, city. The most economical option. |
| Elite Polarised | HD polarised filter that eliminates glare on asphalt and water | Drivers, anglers, cyclists. Maximum visual comfort. |
| Mirror | Outer reflective coating in available colours | Trend, mountain sports, snow. |
| Plano photochromic | Darkens in the sun and clears indoors | Mixed indoor/outdoor use without correction. |
| Plano with blue-light filter | Clear plano lens + screen protection | Relaxation glasses, fashion, digital work without correction. |
How do I identify my glasses' size?
The size (lens width in mm) is engraved inside the left temple. Look for a code like 52-18-140: the first number (52) is the lens width, the second (18) the bridge and the third (140) the temple length. If the engraving has worn off, measure the maximum lens width with a ruler.
Are your frame's factory plastics any good? No. Demo plastics are not optical lenses: they have no UV protection, create reflections and distort light. Replacing them with real plano lenses with certified treatments is an investment in your visual health.
Can't find the size?
Send us a photo of your glasses and the temple and we'll confirm the correct replacement lens before you order.
Ask on WhatsAppAny questions about your sun lenses?
Send us your prescription, a photo of your frame or any question. We'll help you choose the best option.
Write via WhatsAppYes. We offer neutral lenses (flat, with no prescription) with a blue-light filter treatment integrated into the material. These are the so-called «rest glasses» or «non-prescription computer glasses»: perfect if your sight is fine but you want to protect yourself from the eye strain of LED screens without altering your natural vision.
No. Certified neutral lenses have a completely flat surface (0 dioptres) that does not alter natural vision or cause eye damage. What can harm your sight is using the factory demo plastics, which are not optical lenses and can produce distortions and fatigue.
The mirror coating is a layer of metal oxides on the outer surface. It degrades through exposure to sea salt, contact with sunscreens and colognes, dry cleaning with abrasive materials and storage on hot surfaces. Once the peeling has started it cannot be repaired: the only solution is to replace the lens.
It depends on the frame. On acetate or carbon-fibre frames they fit without tools with gentle pressure in under 2 minutes. On metal frames with a closed rim you need a precision screwdriver. On rimless (nylor) frames the process is delicate and we recommend an optical workshop to avoid damaging the holding nylon.
