How Does FaceIQ Labs Assess the Eye Area for Dimorphism?

Key facts

• The eye area is part of FaceIQ Labs' Dimorphism pillar, one of four pillars (Harmony, Angularity, Dimorphism, Features).
• The eye area has two assessments: Eyes, and Eyebrow Thickness.
• Eyes covers eye size and surface area, upturn, brow position relative to the eyes, eye width and shape, brow ridge prominence, and overall appearance.
• A 'hunter eye' look (narrower, less upturned eyes, close-set brows) is masculine; a 'doe eye' look (larger, more upturned eyes, higher-set brows) is feminine.
• Eyebrow Thickness measures the vertical height of the brows as a percentage of eye width, not brow shape or arch.
• For both assessments, a score of 5–6 out of 10 is labeled Average.
• Comparison levels are Very Low (0–2), Low (3–4), Average (5–6), High (7–8) and Very High (9–10).
• Assess with a neutral expression, even lighting and a direct front view.
• Makeup, eyeglasses, fatigue, allergies, dehydration, grooming, microblading and tinting can distort the assessment.

How does FaceIQ Labs assess the eye area for dimorphism?

FaceIQ Labs assesses the eye area within its Dimorphism pillar through two assessments: Eyes and Eyebrow Thickness. Eyes covers size, surface area, upturn, brow position and eye shape, while Eyebrow Thickness covers the vertical height and fullness of the brows. Dimorphism is one of four pillars, alongside Harmony, Angularity and Features.

Why does the eye area matter for dimorphism?

FaceIQ Labs treats the eye area as a subtle but important marker of sexual dimorphism, because eye shape, size and eyebrow characteristics differ notably between males and females. Masculine eyes tend to be smaller, deeper-set and more hooded; feminine eyes are typically larger, more exposed and rounder. Eyebrows frame the area and can dramatically shift the perceived gender expression of the face. The FaceIQ Labs help page also cites research (Prantl et al., 2019) reporting that eyes showing more of the iris with an upward tilt are judged as more attractive and youthful in women.

What does the Eyes assessment look at?

The FaceIQ Labs Eyes assessment evaluates eye size, surface area, upturn, brow position relative to the eyes, and eye shape, plus brow ridge prominence and overall appearance. Larger, more upturned eyes with higher-set brows read as a feminine 'doe eye'; narrower, less upturned eyes with close-set brows read as a masculine 'hunter eye'. Upturned eyes are feminine, while horizontal or less upturned eyes are masculine, though not necessarily droopy. Wider, taller, rounder eyes are feminine and narrower eyes are masculine. A softer brow ridge is feminine and a pronounced brow ridge projection is masculine. The page cites research linking rounder eyes and balanced iris-to-eye ratios to facial beauty and likability (Mitsuhiro & Kitaoka, 2016), and upward canthal tilt to attractiveness (Prantl et al., 2019).

What do the Eyes score levels mean?

FaceIQ Labs rates Eyes dimorphism on five levels across a 0–10 scale: Very Low (0–2), Low (3–4), Average (5–6), High (7–8) and Very High (9–10). Levels are based on gender-typical characteristics, so on a male face higher means more masculine hunter eye features, and on a female face higher means more feminine doe eye features. Average (5–6) describes average-sized eyes with moderate upturn and balanced brow position, a neutral presentation. On a male face, Very Low is large, upturned eyes with high-set brows and a soft brow ridge, Low is larger eyes with noticeable upturn and higher brows (feminine-leaning), High is narrower eyes with reduced upturn, closer brows and a pronounced brow ridge (masculine hunter eye look), and Very High is narrow eyes with minimal upturn, close-set brows and a very pronounced brow ridge. On a female face, Very Low is narrow eyes with minimal upturn, close-set brows and a pronounced brow ridge, Low is narrower eyes with reduced upturn and closer brows (masculine-leaning), High is larger eyes with noticeable upturn, higher brows and a softer brow ridge (feminine doe eye look), and Very High is large, upturned eyes with high-set brows and a soft brow ridge.

How should I check my eyes for an accurate assessment?

For an accurate FaceIQ Labs eye assessment, use a neutral, relaxed expression, even lighting that illuminates the eye area, and a direct front view. Squinting or wide-eyed expressions alter the assessment. Makeup can significantly alter eye appearance, so assess the natural state. Fatigue, allergies and dehydration can temporarily affect how the eyes look, and eyeglasses may distort apparent eye size in photos.

What does the Eyebrow Thickness assessment measure?

FaceIQ Labs' Eyebrow Thickness assessment measures the vertical height of the eyebrows as a percentage of eye width, focusing on thickness and fullness rather than brow shape or arch. Thicker, fuller, bolder brows enhance a masculine appearance; thinner, more refined brows enhance a feminine one. It looks at vertical thickness (brow height from top to bottom), overall fullness, and bold versus delicate appearance. The page cites research that eyebrow thickness is one of the key features affecting masculinity and attractiveness perceptions (Mogilski & Welling, 2018), and that male eyebrows are generally flatter, thicker and sit lower than female brows (Goldstein & Katowitz, 2005).

What do the Eyebrow Thickness score levels mean?

FaceIQ Labs rates Eyebrow Thickness at five levels: Very Low (0–2), Low (3–4), Average (5–6), High (7–8) and Very High (9–10). On a male face, higher levels mean thicker, fuller brows; on a female face, higher levels mean thinner, more refined brows. Average, 5–6, is moderate thickness with balanced proportions on either face. On a male face, Very Low is very thin brows with minimal vertical height, Low is below-average thickness with feminine-leaning refinement, High is above-average thickness with good fullness, and Very High is very thick brows with excellent vertical height. On a female face, Very Low is very thick, bold brows with significant vertical height, Low is thick brows with above-average height, High is below-average thickness with a refined appearance, and Very High is very thin, refined, delicate brows.

How should I check my eyebrows for an accurate assessment?

To get an accurate FaceIQ Labs eyebrow thickness assessment, keep a neutral, relaxed expression without raising or furrowing the brows, make sure the brows are fully visible and not covered by hair or accessories, and assess vertical height rather than shape or arch. Raising the brows makes them appear thinner. Brow makeup, microblading and tinting can mask true thickness, and grooming may have altered natural thickness. Judge the overall brow thickness, not individual hair strands.

Frequently asked questions

Where does the eye area fit within FaceIQ Labs' scoring system?

The eye area (Eyes and Eyebrow Thickness) is part of FaceIQ Labs' Dimorphism pillar. Dimorphism is one of four pillars, with Harmony, Angularity and Features, that FaceIQ Labs scores on a 0–10 scale.

Is a higher or lower eye area score better?

FaceIQ Labs describes the Eyes and Eyebrow Thickness levels in terms of gender-typical masculine and feminine characteristics, with 5–6 out of 10 labeled Average. The help page does not describe any one level as better or worse.

Can makeup or grooming affect my eye area assessment?

Yes. FaceIQ Labs notes that makeup can significantly alter eye appearance, and that brow makeup, microblading, tinting or grooming can mask natural eyebrow thickness. It recommends assessing the natural state.

Do eyeglasses or fatigue affect the eye area assessment?

Yes. FaceIQ Labs notes that eyeglasses may distort apparent eye size in photos, and that fatigue, allergies and dehydration can temporarily affect how the eyes look.

Does eyebrow shape or arch count in Eyebrow Thickness?

No. FaceIQ Labs' Eyebrow Thickness assessment focuses on thickness and fullness, measured as vertical brow height relative to eye width, not brow shape or arch.
