What do I need to order?

Before you order, you'll need to enter a valid eyeglasses prescription (make sure it's not for contacts!) and your pupillary distance (PD). to proceed. The PD is the distance in millimeters between your pupils, and helps us center your prescription correctly in your frames. Make sure this information is provided in your submitting prescription.

What if I need to change or cancel my order?

If there is any change you want to apply to your order or you want to cancel your order, please inform us at hello@tijneyewear.com within 2 hours after you placed the order. If the order is cancelled you will get a refund, but due to the specialized nature of prescription lenses and blue light filtering lenses, we may still charge the part of the lenses after 12 hours of payment. Kindly note that no changes can be made if the order has been shipped out and completed.

What's the status of my order?

To check on the status of an order, sign into your account on tijneyewear.com using the email address and password you used during checkout. You will find you order details after your purchase. You're always welcome to reach out via emailing hello@tijneyewear.com or find us by clicking the Service button.

How do I order multiple pairs of glasses with different prescriptions?

If you are interested in purchasing multiple pairs using different prescriptions (e.g., one for you and one for your spouse; one pair for distance and one for reading), please place a separate order for each prescription. Free shipping is applied to every order, so don't worry about getting charged extra for the separate orders!


How do I submit my prescription?

There are two types of prescription lenses we provide: Single Version (for seeing near or distance) lenses and Blue light filter. You can select either type at the product detail page. Before submitting the order, please kindly enter your OD (Latin terms for right eyes), OS (Latin terms for left eyes), PD(your pupillary distance) which are 3 important statistics.

How do I obtain a prescription?

The easiest and most trusted way to obtain your prescription is to see your local optometrist. Please be sure to ask your doctor to include your pupillary distance (PD) on your prescription! If you have any problems while entering the prescription, kindly contact us at hello@tijneyewear.com.


Regarding the function of the products, we now have 4 main types available: optical eyeglasses and sunglasses. Only optical glasses can be prescribed to single-vision or Blue light filtering glasses.

There is one special sunglasses lens that is truly unique and popular-Polarized polycarbonate lenses. They are:

• Thin and light plastic lenses

• Anti-scratch, anti-glare, and superhydrophobic coatings included

• Provide 100% UV protection

Our sunglasses' 100% UV protective function also render them perfect outdoor accessories.

Prescription sunglasses are available for nearsightedness only. Please check your prescription before submitting all information. All the lenses in the Prescription Sunnies page are customized. Due to the specialized nature of prescription lenses and all blue light filter lenses (with or without prescription), customized lenses are non-refundable, except the frame part. We may still charge you the lenses if you cancel the order after 12 hours of payment or return the prescription sunglasses.

Where can I find my frame's measurements?

On each product page, the frame measurements are listed as three numbers. Most glasses (including all TIJN frames) have these numbers printed on the inside of the temple arm. You can use these measurements to compare our frames to the size of your current glasses.

What's the best way to clean my lenses?

To clean your lenses, simply rinse them with a mild dish soap and lukewarm water, and dry them with a soft cloth. For day-to-day cleaning of light smudges, a few swipes of the pouch included in your case should do the trick. Please be careful to avoid using hot water on your lenses (especially if they are high-index lenses), as they can develop bubbles or cracks when exposed to high heat.
