Buying prescription glasses online has become an easy and convenient way to quickly get the eyewear you need. From selecting frames and lens coatings to entering glasses prescription details, the steps can also be overwhelming for a first-time buyer to navigate.

Lentiamo offers an easy-to-follow five-step process for ordering prescription glasses online. Learn how to order glasses online from Lentiamo below!

Step 1. Choose your frames

First, navigate to the prescription glasses category and choose your favorite frames from a wide selection of stylish options in the e-shop.

Unsure if your chosen frames will work out? Find your glasses size to ensure a proper fit.

Helpful hints: Knowing which glasses complement your face shape can help you pick styles that best suit your features. If you're still stuck, look for the Virtual Try-On symbol to virtually try hundreds of styles from home. And finally don't forget to check out the latest glasses trends to see what styles are popular.

Step 2. Select your lenses

After you've chosen your frames, select your glasses lenses. You'll choose between lenses for reading or distance and choose your lens coatings at this step.

Reading / Distance

  • Reading – If your vision problems came with age and you need glasses mainly for reading, this might be the option for you.
  • Distance β€“ If you need general-use lenses for any distance (near or far), this is likely the option you need.


  • Antireflection β€“ Anti-reflective coating that provides basic protection against water and dust
  • Superhydrophobic coating with antireflection – Hydrophobic coating to protect from water and dust
  • Sunglasses β€“ Customised sunglasses in the colour of your choice
  • Computer "Blue Cut" with anti-reflection and hydrophobic coating β€“ Specially developed filter with blue light protection

Step 3. Add prescription details

Then it's time to add your prescription details. You can add your prescription details in one of three ways:

  • Upload prescription 
  • Enter manually 
  • Convert contact lens prescription 

Accurate prescription details are essential for getting the right eyewear. Our platform makes it easy to input your prescription information. Additionally, measuring your pupillary distance (PD) is crucial for ensuring proper lens alignment. If you're unsure, learn how to measure your PD accurately.

Note: If you've chosen custom sunglasses, you'll need to select your lens type and tint before adding your prescription details. You'll choose between plain, gradient, mirrored, polarised, or self-tinting lenses.

Step 4. Choose index

Lentiamo provides a selection of lens indexes, enabling you to tailor your lenses to match your prescription and preferences. You'll be given the choice between four index options.

  • Standard – Standard hard material ideal for lower spheres
  • Slim – Recommended option with extra hardened glass and UV protection
  • Extra slim – Extremely durable aspherical lenses with a natural look, even for high dioptres
  • Ultra slim – Best choice for high spheres

Step 5. Finalise your order

In the final steps, review your selected frames, lenses, and prescription details to ensure everything is accurate. 

Add your payment and delivery details before clicking "Complete order and pay." After that, you'll receive an order number and confirmation email.
