What You Need to Know Before Buying a PD Ruler Online
When it comes to measuring pupillary distance (PD), having the right tools is essential. Many optometrists and eye care professionals use PD rulers to measure the distance between a patient’s pupils. If you’re looking to buy a PD ruler online, there are some important things you should know before making your purchase.
Accuracy and Durability
The most important thing to consider when buying a PD ruler online is accuracy and durability. Make sure the ruler you are purchasing is made of high-quality materials that will last for years. Also, make sure the measurements on the ruler are accurate and easy to read. The last thing you want is an inaccurate measurement that could lead to incorrect prescriptions or eyewear fitting issues.
Size and Design
The size and design of the PD ruler should also be taken into consideration when shopping online. Most PD rulers come in two sizes: standard (2 inches) and large (3 inches). Depending on your needs, you may want to opt for a larger size if you plan on measuring larger pupils or if you need more accuracy in your measurements. Additionally, make sure the design of the ruler is ergonomic and comfortable to use. This will ensure that you get accurate measurements every time.
Price Point
Finally, consider your budget when shopping for a PD ruler online. Prices can range from as low as $5 up to $50 or more depending on quality and features. Make sure you compare prices from different retailers before making your purchase so that you can get the best deal possible.
Overall, buying a PD ruler online can be an easy process as long as you know what to look for in terms of accuracy, durability, size, design, and price point. With these tips in mind, you can be sure that your purchase will be worth it in the long run.
