Frame Measurements

When selecting frames, there are five key measurements to consider:

Lens Width

This measures the horizontal width of one lens at its widest point. It’s often called the “eye size” by some doctors.

Nose Bridge Width

This measures the distance between the lenses, where the frame rests on your nose.

Lens Height

This measures the vertical height of a lens at its tallest point.

Frame Width

The width of the entire frame, measured horizontally from temple to temple, inside the frame.

Temple Length

This measures the length of the arms (temples) of the glasses, which rest on your ears to keep the glasses in place.

Reading Frame Measurements

Frame measurements are typically written in millimeters, and most glasses have these measurements listed on the inside of the temple arms. The numbers are usually in the format: lens width x nose bridge width x temple length.

For example, if you see 51-18-140 inside the temple, it means:

• Lens width: 51mm
• Nose bridge width: 18mm
• Temple length: 140mm

Important Notes for Bifocal and Progressive Lenses

• Bifocal glasses require a lens height of at least 27mm.
• Progressive glasses need a lens height of at least 29mm.

This ensures we create glasses with the proper segment height for clear vision at all distances.

Frame Types: Full Rim, Half Rim, or Rimless?

Full Rim

Full rim frames surround and protect the entire lens. They are sturdy, can handle thicker lenses, and provide a classic, bold look.

Half Rim

Half rim glasses only cover the top portion of the lens, leaving the bottom exposed. They are lighter than full rim frames but still provide a stylish design.

Rimless

Rimless frames don’t have any frame around the lens, creating a minimalist, delicate look. These frames are more fragile and require impact-resistant lenses (like polycarbonate) to help prevent breakage.

Frame Materials: What’s the Difference?

Acetate:
Acetate frames are strong, lightweight, and flexible. They are more durable than typical plastic frames and come in a variety of colors and patterns.

Aluminum:
Aluminum frames are lightweight, corrosion-resistant, and environmentally friendly (they’re recyclable!). They offer strength similar to steel without the bulk.

Metal:
Metal frames are sleek and minimalist, often thinner than plastic frames. They are perfect for those who prefer half rim or rimless options.

Plastic:
Plastic frames are affordable, versatile, and lightweight. They’re also highly customizable, with a wide range of colors and patterns, making them a great option for accessorizing your look.

Pure Titanium:
Titanium frames are incredibly strong, lightweight, and hypoallergenic. They are ideal for people with metal allergies and are resistant to corrosion.

Choosing the right frame involves understanding your personal preferences in terms of style, comfort, and durability.
