Step-by-Step Guide to Buying Online

Step 1: Get a Current Prescription

You need a valid prescription from an eye doctor. In the US, prescriptions are typically valid for 1-2 years. Your prescription should include:

• OD (Right Eye) and OS (Left Eye) measurements
• Sphere (SPH) - Nearsighted (-) or farsighted (+)
• Cylinder (CYL) - Astigmatism correction (if applicable)
• Axis - Angle of astigmatism (if applicable)
• Add - Reading addition for bifocals/progressives (if needed)
• Pupillary Distance (PD) - Distance between pupils

Step 2: Measure Your Pupillary Distance (PD)

PD is crucial for proper lens alignment. If it's not on your prescription, you can measure it yourself:

DIY Method:

1. Stand 8 inches from a mirror
2. Hold a ruler against your eyebrows
3. Close your right eye
4. Align the ruler's 0mm with the center of your left pupil
5. Look straight ahead and measure to the center of your right pupil
6. Average PD for adults: 54-74mm

App Method:

Many online retailers offer free PD measurement apps. These use your phone's camera and are surprisingly accurate.

Step 3: Choose Your Frames

This is the fun part! Consider:

• Face shape - See our face shape guide
• Frame material - Acetate, plastic, metal, titanium
• Frame size - Check measurements (lens width, bridge, temple length)
• Style - Professional, casual, trendy, classic
• Color - Match your skin tone and wardrobe

Step 4: Select Your Lenses

Lens options can be confusing. Here's what you need to know:

Lens Materials:

• Standard plastic (CR-39) - Cheapest, thickest
• Polycarbonate - Impact-resistant, good for kids/sports
• High-index (1.67, 1.74) - Thinner, lighter for strong prescriptions
• Trivex - Lightweight, clear, impact-resistant

Lens Coatings:

• Anti-reflective (AR) - Reduces glare, highly recommended
• Scratch-resistant - Protects lenses, usually included
• UV protection - Blocks harmful UV rays
• Blue light blocking - Reduces digital eye strain
• Photochromic (Transitions) - Darken in sunlight

Lens Types:

• Single vision - One prescription throughout
• Bifocals - Two prescriptions (distance and reading)
• Progressives - Gradual transition, no visible line

Step 5: Enter Your Prescription

Carefully enter all prescription values. Double-check:

• Correct eye (OD vs OS)
• Positive (+) or negative (-) signs
• All decimal points
• PD measurement

Step 6: Review and Order

Before clicking "Buy":

• ✅ Verify prescription details
• ✅ Confirm frame size and color
• ✅ Check lens options and coatings
• ✅ Review return policy
• ✅ Look for discount codes
• ✅ Consider ordering a backup pair
