Choose coloured contact lenses in two stages: first choose a lens that is professionally fitted to your eyes and prescription, then choose the colour and visual effect you want.

1. Start with fit and prescription

  • Use a current contact-lens prescription. A glasses prescription does not include all the information needed to fit contact lenses.
  • Match the prescribed power, base curve and other specifications. Do not assume a popular base curve or diameter will fit everyone.
  • Plano (0.00) means no vision correction; it does not remove the need for a safe fitting. In the United States, decorative plano lenses also require a prescription.
  • If you have astigmatism, dry eye, recent eye surgery or another eye condition, ask your eye-care professional which lens design is appropriate before ordering.
Do not self-prescribe. Contact-lens power can differ from glasses power, especially at stronger prescriptions.

2. Understand the product specifications

Specification What it tells you
Power Vision correction. Select only the power prescribed for that eye; left and right eyes may differ.
Base curve The curvature of the lens. It affects fit and movement and should match professional fitting advice.
Diameter The overall lens width. It is a fit measurementโ€”not a reliable measure of how large the printed colour will look.
Graphic diameter The printed colour area. A larger graphic diameter or stronger limbal ring can create a more enlarging effect.
Replacement schedule The maximum time after opening before replacement. For GEO lenses sold here, replace no later than three months (90 days), or sooner when the packaging or your eye-care professional says so.

3. Choose the effect

Natural enhancement

Look for a softly blended, multi-tone pattern and a subtle limbal ring. Start with natural coloured contact lenses or GEO Eyevelyn.

Dolly-eye definition

A stronger limbal ring and larger graphic area create more visible definition. Compare dolly-eye circle lenses, GEO Princess Mimi and GEO Cafรฉ Mimi.

Bold colour change

More opaque patterns generally create stronger contrast, particularly on dark irises. Browse blue, green, grey and purple coloured lenses.

4. Consider your natural eye colour

  • Dark brown eyes: more opaque patterns and defined limbal rings usually create the most visible change. Brown and grey can look softer; blue, green and violet create more contrast.
  • Light brown or hazel eyes: multi-tone brown, green and grey patterns can blend naturally, while cooler colours create stronger contrast.
  • Blue, grey or green eyes: lower-opacity patterns may blend with the iris; warmer brown or hazel shades can create a noticeable change.

The final appearance varies with iris colour, lighting, pupil size and the exact print pattern. Product photography is a guide, not a guarantee of an identical result.

5. Check care and replacement before buying

Only choose a reusable lens if you can follow its cleaning, disinfection and storage routine. Never sleep, shower or swim in these lenses, never share them, and never use water or saliva. Read the full Contact Lens Safety and Care Guide.
