Compare Las Vegas Ash Blue and Dark Night Black on fit, pupil clearance, and color effect to choose the right subtle prescription lens for your look.
Quick answer
Choose Las Vegas Ash Blue if you want a soft blue-gray tint and your pupils are small enough for its reduced pupil hole; choose Dark Night Black if you prefer a natural black finish with a standard pupil opening and a slightly larger diameter.
Why pupil hole size is the deciding factor
Las Vegas Ash Blue has a smaller pupil hole than normal color lenses, and the catalog warns it can obstruct vision when worn. That makes it a poor choice for anyone with larger pupils, especially in low light. Dark Night Black does not carry that warning, so it is the safer default for daily wear.
Diameter and water content: small differences that affect comfort
Las Vegas Ash Blue measures 14.2mm in diameter, while Dark Night Black is 14.3mm. Both share a base curve of 8.7mm and 40% water content in silicone hydrogel or MPC material, so the comfort profile is similar. The 0.1mm difference is minor, but a larger diameter can feel slightly more noticeable on smaller eyes.
Color effect: ash blue versus black
Ash Blue gives a cool, muted blue-gray tint that reads as subtle rather than bright. Dark Night Black deepens the iris edge for a natural, defined look. If your goal is a quiet color change, Ash Blue adds a visible tone; if you want definition without obvious color, Black is the more conservative pick.
