Two 1-Month Looks, Two Different Vibes
If you're deciding between the It's Me Coco Gray and the Circlean Big Black, you're really choosing between two distinct styles. The Coco Gray offers a soft, calm gray with a subtle circle line for an urban, natural-looking enhancement. The Circlean Big Black is a bold black circle lens designed to make your eyes look larger and more striking, even without makeup. Both are 1-month (monthly) colored contacts sold in packs of 2 pieces, but their fit and effect differ in ways that matter for your daily wear.
Specs at a Glance
- It's Me Coco Gray: It's Me Coco Gray: Total Dia 14.2mm, Graphic Dia 13.4mm, Base Curve 8.6mm, Water Content 40%, Material HEMA The smaller graphic diameter and softer gray tint create a subtle, natural-looking enhancement rather than a dramatic color change.

It's Me Coco Gray - Circlean Big Black: Circlean Big Black: Total Dia 14.3mm, Graphic Dia 13.8mm, Base Curve 8.8mm, Water Content 43%, Material Silicone Hydrogel The larger graphic diameter and deep black color deliver a more noticeable circle-lens effect, while the silicone hydrogel material may offer different comfort characteristics.

Fit and Sizing: What to Check First
Both lenses come in a range of powers, from 0.00 (plano) to -3.25, so you can choose your prescription. But fit is about more than power. The It's Me Coco Gray has a base curve of 8.6mm, while the Circlean Big Black has a base curve of 8.8mm. A base curve that matches your eye's curvature is essential for comfort and proper movement. If you're new to colored contacts, it's wise to have an eye care professional confirm your fit, as the supplied information does not include detailed fitting instructions.
Key Differences: Coco Gray vs Big Black
- Color effect: Coco Gray provides a soft, muted gray with a circle line for a calm, urban charm. Big Black is a bold, solid black that creates a dramatic enlargement effect.
- Graphic diameter: Coco Gray's graphic diameter is 13.4mm, while Big Black's is 13.8mm. The larger graphic diameter of Big Black means more of the iris is covered, intensifying the circle-lens look.
- Material and water content: Coco Gray uses HEMA with 40% water content; Big Black uses silicone hydrogel with 43% water content. Silicone hydrogel is often associated with higher oxygen permeability, but individual comfort varies.
- Total diameter: Both are similar: Coco Gray is 14.2mm and Big Black is 14.3mm. The total diameter affects overall lens size on the eye, but the graphic diameter drives the visible color effect.
Which One Fits Your Style?
Choose the It's Me Coco Gray if you want a subtle, natural-looking gray that adds a calm, sophisticated touch without overwhelming your features. It's a great choice for everyday wear, especially if you prefer a softer look. Choose the Circlean Big Black if you want a more dramatic, eye-enlarging effect that stands out, even without makeup. Its larger graphic diameter and deep black color make a bolder statement, ideal for nights out or when you want your eyes to be the focal point.
Price and Value
- It's Me Coco Gray: It's Me Coco Gray is priced at USD 11.70 (catalog comparison price USD 18.00). A more budget-friendly option for a monthly pair, especially if you prefer a subtle gray look.
- Circlean Big Black: Circlean Big Black is priced at USD 13.68 (catalog comparison price USD 19.00). Slightly higher price reflects the silicone hydrogel material and the bolder design, which may be worth it for the dramatic effect.
Important Considerations Before Buying
Remember that these are 1-month lenses, meaning you should replace them monthly. Both come as 2 pieces per box, so you get a pair for one month. The supplied information does not include specific care or safety instructions, so always follow the guidance from your eye care professional and the manufacturer's packaging. If you have any doubts about fit or suitability, consult an optometrist before purchase.
