2. Quality Standards, Certifications & Fitting Parameters
Safety and regulatory compliance are fundamental to our manufacturing operations. Stephies Lens CO.,LTD operates sterile production facilities certified under ISO 13485 (Medical Devices Quality Management Systems).
All our contact lens products carry official CE certification, verifying adherence to European medical device standards. Technical dossiers, batch test reports, and compliance documentation are readily available upon request to assist with local market registration.
Excessive lens movement or instability on the eye typically stems from improper dimensional fit or inverted wear:
1. Base Curve & Diameter Mismatch: Human corneal curvature varies individually. If the base curve of a lens is too steep (tight), it restricts necessary movement and tear exchange; if it is too flat (loose), the lens slides off center when blinking. Customers should consult an optometrist to confirm their anatomical base curve requirement.
2. Inverted Lens Wear: If an end-user wearing a previously comfortable lens suddenly experiences excessive movement or irritation, the lens is likely inside out. Inverting the lens back to its natural cup shape resolves the issue immediately.
3. Lens Hygiene, Usage Precautions & Patient Safety
No. Under no circumstances should wearers sleep while wearing soft colored contact lenses unless the product is specifically clinical-grade extended-wear certified.
During sleep, closed eyelids drastically reduce atmospheric oxygen supply to the cornea. Wearing lenses overnight physically blocks oxygen transmission, creating corneal hypoxia. This can trigger corneal neovascularization (abnormal blood vessel growth), severe corneal edema, acute pain, and heightened susceptibility to vision-threatening bacterial infections.
No. Contact lenses must never come into direct contact with non-sterile water sources, including swimming pools, tap water, hot tubs, ocean water, or showers.
Water harbors harmful microorganisms such as Acanthamoeba protozoa and Pseudomonas aeruginosa bacteria. Soft hydrogel materials readily absorb water toxins, trapping pathogens against the corneal surface, which can cause devastating microbial keratitis or corneal ulcers. Lenses should be removed prior to any water exposure.
Contact lenses should always be inserted prior to applying cosmetic makeup. Inserting lenses into a clean eye prevents facial creams, foundation powder, or mascara residue on fingers from transferring onto the lens surface.
Additionally, when using hairsprays or setting mist, wearers must keep their eyes tightly shut during application until micro-droplets settle. Conversely, contact lenses should always be removed before cleansing facial makeup at the end of the day.
If a lens becomes dehydrated or folds and sticks to itself, users must never forcibly peel the edges apart with fingernails, as this will tear the delicate hydrogel matrix.
To safely separate a stuck lens, place it into a clean lens case or the palm of a hand, submerge it completely in fresh, sterile multi-purpose contact lens solution, and let it soak for several minutes. Gently massage the lens back and forth using the pad of a clean index finger until it absorbs solution and regains its natural dome geometry.
