Step 1: Determine the Lens Type

The first step in ordering edging of lenses for your 3D printed glasses frame is to determine the type of lens you need. There are several different types of lenses, including single vision, bifocal, and progressive lenses. Single vision lenses are the most common type of lens and are used for correcting one type of vision problem. Bifocal lenses are used for people who need both distance and close-up correction, while progressive lenses are used for people who need multiple vision corrections in one lens. Once you determine the type of lens you need, you can move on to the next step.

Step 2: Determine the Lens Material

The next step in ordering edging of lenses is to determine the lens material. There are several different materials to choose from, including plastic, polycarbonate, and high-index lenses. Plastic lenses are the most affordable option and are suitable for people with low to moderate prescriptions. Polycarbonate lenses are more durable and impact-resistant, making them a good choice for people with active lifestyles. High-index lenses are the thinnest and lightest option, making them a good choice for people with higher prescriptions.

Step 3: Measure the Pupillary Distance (PD)

The pupillary distance (PD) is the distance between the center of each pupil. It is an important measurement when ordering lenses because it helps ensure that the optical center of the lens is aligned with the center of the eye. To measure your PD, you can use a ruler or a PD measuring tool. If you're not sure how to do this, you can ask your optometrist or optician to measure your PD for you.

Step 4: Choose the Lens Coating

The next step in ordering edging of lenses is to choose the lens coating. There are several different coatings to choose from, including anti-glare, scratch-resistant, and UV protection. Anti-glare coating can help reduce glare and improve the clarity of your vision, while scratch-resistant coating can help protect your lenses from scratches. UV protection is important for protecting your eyes from harmful UV rays.

Step 5: Place Your Order

Once you have all the information you need, you can place your order for edging of lenses. You can order your lenses from a variety of sources, including your optometrist, optician, or online eyewear retailers. When placing your order, be sure to provide all the necessary information, including the type of lens, lens material, PD, and lens coating.

Step 6: Wait for Delivery and Installation

After you place your order, you will need to wait for your lenses to be delivered. Once you receive your lenses, you can take them to your optometrist or optician to have them installed in your 3D printed glasses frame. Your optometrist or optician can ensure that your lenses are properly aligned and fitted to your frame.

How can an optometrist measure the shape of a lens if there's no existing lens?

Optometrists can use different methods to measure the shape of a lens without an existing one. One way is to use a special machine called the Briot Scan 8 tracer. This machine can easily trace the shape of a glasses frame and provide accurate measurements, even for difficult frames with curves. Another way is to use a 3D scanner or manual measuring tools to get the shape of the glasses frame. Overall, the specific method used will depend on the optometrist's preference and the equipment available in their office.
