Mineral Lenses: The Benchmark for Optical Clarity
Visionet, your online optician, is one of the few specialists to offer a complete range of high-quality mineral lenses: single vision, progressive, and sun lenses. Renowned for their optical purity, dimensional stability, and resistance to micro-scratches, they provide clear and lasting vision. At Visionet, you can order mineral lenses with prescription (single vision and progressive), but also without correction to transform sunglasses with premium lenses or to get durable clear work glasses.
1Why choose mineral lenses?
Derived from a silica base, mineral glass ensures high light transmission and stability of refractive indices over time. Its naturally hard surface limits everyday micro-scratches. The result: a very pure image, sharp contours, and exemplary color fidelity.
- High optical quality: uniform sharpness and contrast.
- Durability: naturally more resistant surface to micro-scratches.
- Stability: regular optical properties, less sensitive to temperature variations.
2Our Mineral Ranges: Single Vision, Progressive & Sun Lenses
We order your lenses from our partner lens manufacturers, then assemble them in our workshop according to your prescription and measurements (PD, heights, wearing parameters).
Mineral Single Vision Lenses
Single vision (distance, rest) or reading, for maximum clarity and excellent stability.
Mineral Progressive Lenses (HD Free-Form)
Point-by-point calculation to widen the useful field, soften near-intermediate-distance transitions, and reduce peripheral distortions for more natural vision.
Mineral Sun Lenses
With or without prescription, in grey (neutral), brown (contrast), and G15 green (anti-glare balance / color fidelity) tints.
Compatibility (mandatory): full-rim frames only and lens width ≤ 56 mm depending on the frame geometry. Our opticians verify feasibility before assembly.
3Comfort & Frame Choice
Mineral lenses are heavier and less shock-tolerant than organic lenses. For optimal comfort, choose a frame adapted to your morphology (stability on the nose, hold at the temples). Trying on frames in person helps validate size, bridge, and support points.
4Ordering Mineral Lenses with Visionet
Ordering Steps (frames & mineral lenses)
1) Choose a compatible full-rim frame (lenses ≤ 56 mm).
2) On the product page, click on "Add lenses" (or "Change lenses" for sunglasses).
3) Select the type of lenses (single vision, progressive, sun).
4) At step 2 or 3, the mineral lenses option will be offered if your configuration is compatible.
5) Enter your measurements (prescription, PD) then validate your online quote.
Treatment & Thinning Options (mineral specificities)
Regarding treatments, the choice is more limited than for organic lenses: blue light filter not available, Transitions GEN S not available (only a standard photochromic).
However, thinning options are more extensive for very strong prescriptions: more indices available to obtain thinner and more aesthetic lenses.
5Buying Guide: Are mineral lenses right for you?
Mineral lenses excel when seeking maximum optical purity, dimensional stability over time, and a highly scratch-resistant surface. They are suitable for demanding wearers working in bright environments, intensive readers, lovers of contrasted images, or anyone sensitive to neutral color reproduction.
When to choose mineral lenses?
- You prioritize image quality and stability.
- You want natural resistance to micro-scratches.
- You have a strong prescription: thinning options in mineral lenses optimize aesthetics.
- Your frame is full-rim and compatible with a lens width ≤ 56 mm.
When to prefer another material?
- You are looking for minimal weight (organic is lighter).
- You need advanced treatments not available in mineral lenses (e.g., blue light filter, recent photochromic lenses).
- Your frame is rimless or semi-rimless (not recommended for mineral lenses).
Mineral Thinning Indices: The Impact
Mineral lenses often offer more index steps for very strong prescriptions: the higher the index, the thinner the lens can be (thinner edges, more aesthetic appearance), while retaining the optical signature of mineral glass. The choice depends on the power, the caliber size, and the frame geometry.
Care & Durability
Even if mineral lenses are highly resistant to micro-scratches, use an appropriate spray and a clean microfiber cloth. Avoid solvents and dry wiping. Store your glasses in a case to preserve transparency and treatments.
Tip: validate size, bridge, and fit by trying on several frames in person. A frame well-adapted to your morphology is essential to fully enjoy mineral lenses.
FAQ – Mineral Lenses
Are mineral lenses "better" than organic lenses?
Not necessarily. Approximately 90% of lenses sold worldwide are organic lenses, as they are lighter and offer many treatment options. Mineral lenses meet specific needs (optical purity, dimensional stability, naturally harder surface). It's not a question of "better or worse," but of use, priorities, and compatible frame.
Are mineral lenses sharper than organic lenses?
Generally, mineral lenses offer optical purity and good stability, with a naturally harder surface. Modern organic lenses remain excellent and lighter; the choice depends on your priorities.
Can mineral progressive lenses be made?
Yes. We offer HD Free-Form mineral progressive lenses with widened useful fields and softened transitions, customized to your frame and measurements.
Which frames are best suited?
Quality full-rim frames are mandatory for mineral lenses (lens width ≤ 56 mm). Rimless or semi-rimless frames are not recommended due to fragility to impacts.
What about mineral sun lenses?
We produce mineral sun lenses (with or without prescription) in grey, brown, and G15 green tints for good glare control and faithful color reproduction.
Weight and comfort: what should be considered?
Mineral lenses are heavier. Choose a frame adapted to your morphology and validate size, bridge, and fit before ordering.
