Which tint can change the present eye color?

• A. Opaque Tint
• B. Clear Tint
• C. Neutral Tint
• D. Gradient Tint

Answer: (C)

Tint choices in eyewear filter light in different ways, which affects how the iris is perceived. To change the eye color appearance, the tint must modify how light interacts with the iris rather than simply dimming or preserving it. A neutral tint is designed to adjust light transmission without imparting a strong color bias, so under typical lighting it can subtly shift the perceived hue of the iris. Clear tint changes nothing, gradient tint tends to preserve much of the natural iris look while altering brightness, and opaque tint would cover the iris more fully for a dramatic change. So, in this context, the neutral tint offers a controlled way to alter the appearance of the eye color.
