FAQs

Yes, a valid prescription is required to order prescription glasses online.
We need your accurate prescription details like sphere (SPH), cylinder (CYL), axis, and pupillary distance (PD) to craft lenses that perfectly match your vision needs. Please upload your prescription to proceed with your order. This ensures your glasses provide clear vision and comply with optical standards.

Yes, but your prescription should be up to date.
We generally accept prescriptions issued within the last 2 years from the date of your eye examination. This is for your eye health and safety. If your prescription is older, we recommend getting a new eye exam before ordering.

The easiest way is to check the numbers printed inside the temple of your current glasses (e.g., 52-18-140). If you don’t have a current pair, you can measure your face width at home. Still not sure? Detailed instructions are available in our Size & Measurement Guide.

Yes. VionGlasses is an out-of-network provider.
We provide a detailed itemized receipt that clearly separates the frame cost and the lens cost for reimbursement. Coverage varies by plan, so please check with your provider before ordering. We do not bill insurance directly.

Yes, blue light blocking lenses can help reduce digital eye strain, headaches, and sleep disruption caused by prolonged screen time.
Our blue light filtering lenses are designed with advanced coatings that block a significant portion of harmful blue light while maintaining natural color perception. Many of our customers report noticeable comfort during long work or study sessions. Learn more about whether you need blue light filtering glasses.

Pure titanium is strong but can bend permanently when force is applied. Beta-titanium, on the other hand, is highly flexible and has excellent “memory” — it snaps back to its original shape after bending. This makes beta-titanium frames more durable and comfortable for everyday wear. Our premium titanium collecion frames use beta-titanium for superior performance. Discover the full comparison here.

Yes, Korean glasses have earned their global reputation by perfectly balancing cutting-edge technology and trend-setting aesthetics.
They offer excellent lightweight comfort, premium materials like Beta Titanium, modern minimalist designs, and great value for money. Many customers find them more comfortable and better quality than traditional luxury brands at a more reasonable price.

Every VionGlasses frame proudly displays “Made in Korea” on the inside of the temple arm. We are fully transparent about our origin — all frames and lenses are expertly crafted by experienced opticians in Korea using high-precision manufacturing.

If you have a strong prescription (-6.00+ and higher), 1.74 high index lenses are worth the upgrade. They’re significantly thinner, lighter, and more comfortable than standard lenses, while reducing the “thick lens” look and small-eye effect common with high prescription glasses.
For people with high myopia or strong prescriptions, our 1.74 aspheric lenses improve both appearance and comfort while giving you more flexibility to choose stylish frames. Best of all, with VionGlasses, the upgrade is only $40 extra.

Yes. With 1.74 high-index lenses, you’re no longer limited to small frames even with strong prescriptions. You can confidently wear slim, oversized, and fashion-forward styles.
We recommend pairing them with lightweight Titanium or TR90 frames for better balance. This combination keeps glasses thin, light, and comfortable for all-day wear. Explore our lightweight frames collection here.

VionGlasses ships from Korea, so any customs duties will be covered by us.
However, local VAT, GST, or other consumption taxes may still apply depending on your country’s rules. These local taxes, along with any carrier handling fees, are the recipient’s responsibility and are usually collected by your local delivery service upon arrival.
We always provide a clear commercial invoice with every shipment to help make the customs process as smooth as possible. For the most accurate information regarding your specific order, we recommend checking with your local customs office or tax authority.

We take full responsibility for any shipping damage. Please contact us within 7 days of delivery with photos of the damaged package and glasses.
We will either remake your glasses free of charge or issue a full refund, whichever you prefer. Our goal is to make sure you receive perfect glasses.

Occasional delays can happen due to customs processing, weather, or carrier issues. Most packages resume movement within 1–3 days. You can check the latest status on our Track My Order page using your tracking number. If there’s no update for more than 3 business days, please contact us — we’ll actively follow up with the carrier on your behalf.
