Before making a purchase, here are 10 important things you should know.

10 Things to Know Before Buying Optical Lenses

Understand the Different Types of Optical Lenses

Before buying, it is important to understand the main types of lenses available:

Single vision lenses
Bifocal lenses
Progressive lenses
Blue light blocking lenses
Photochromic lenses
Anti blue photochromic lenses
Polycarbonate lenses
High index lenses
Myopia control lenses
RX lenses

Choosing the right type depends on your target market and customer needs.

Know the Lens Materials

Lens material directly affects clarity, weight, and durability.

Common materials include:

CR-39
Polycarbonate
High-index lenses (1.61 / 1.67 / 1.74)
Glass

High-index lenses are thinner and lighter, making them ideal for customers with strong prescriptions.

Pay Attention to Lens Index

Lens index determines how thin and light the lens will be.

Common indexes include:

1.499
1.56
1.59
1.61
1.67
1.71
1.74

In the same measurement, the index is higher, the lens is thinner.

Check the Lens Coating Options

Lens coatings improve both performance and durability.

One of the most important coatings is:

Anti-scratch coating
Anti-reflective coating

Other useful coatings include:

Anti-glare coating
Super hydrophobic coating
Anti-fog coating
Blue light filtering coating
Spin photochromic coating

High-quality coatings can significantly enhance the user experience.

Understand Your Target Market

Different markets require different types of lenses.

For example:

South American Market → Blue cut lenses, photochromic lenses, anti blue photochromic lenses
African Market → Photochromic lenses, anti blue photochromic lenses
Southeast Asian Market → Single vision lenses, bifocal lenses

Understanding your customer base helps you choose the right products.

Check Certifications and Standards

If you are importing lenses, certifications are essential.

Common certifications include:

CE marking
FDA registration
ISO 9001/13485

These ensure that the lenses meet regulatory requirements in your market. We also can provide Certificate of Origin (CO) for you to pay less taxes when clear the customs.

Consider MOQ and Pricing

Minimum order quantity (MOQ) varies depending on the supplier and product type.

Typical situations:

Common lenses (single vision lenses, blue cut lenses etc.) → Low MOQ (300 pairs for each item)
High index lenses (1.67 / 1.74)→ Low MOQ (100 pairs for each item)
Customized RX lenses → No MOQ, we can customized according to your prescription

Bulk purchasing usually reduces unit cost, making wholesale sourcing more cost-effective.

Evaluate the Supplier’s Manufacturing Capability

Choosing the right supplier is critical.

A reliable manufacturer should have:

Production workshops
Coating machines
Quality control systems
Packing machines

Many buyers source from experienced manufacturers in Danyang, known for large-scale lens production.

Check Delivery Time and Logistics

Lead time is an important factor for inventory planning.

Typical production timelines:

Small batch in stocks: 7~10 days
Bulk production: 20–30 days
RX prescription lenses: 3–7 days

You should also consider shipping options such as express, air freight, or sea freight.

Look for OEM and Private Label Options

If you are building your own brand, OEM services are essential.

Most manufacturers offer:

Custom logo printing
Private label packaging
Product customization

This allows you to differentiate your products in the market.

Buying optical lenses involves more than just comparing prices. Buyers need to consider lens types, materials, coatings, quality, certifications, and supplier reliability.

By understanding these 10 key factors, distributors and optical shops can make better purchasing decisions and build long-term partnerships with reliable manufacturers.
