# **How to Choose 24 FLAT RED 5mm or 3/16″ Eyes for Fly Tying Lures**
When it comes to fly tying, the details matter—especially when selecting the right eyes for your lures. The **24 FLAT RED 5mm (or 3/16″) eyes** are a popular choice among anglers for their visibility and effectiveness in attracting fish. But how do you decide whether 5mm or 3/16″ is the best fit for your fly patterns? In this guide, we’ll break down the key factors to consider when choosing these eyes for your next fly tying project.
## **Understanding the Basics: 5mm vs. 3/16″ Eyes**
At first glance, **5mm and 3/16″ eyes** may seem interchangeable, but there are subtle differences that can impact your fly’s performance.
– **5mm Eyes**: These are slightly larger, offering better visibility in murky water or low-light conditions. They work well for larger fly patterns, such as streamers and saltwater flies, where extra flash and attraction are needed.
– **3/16″ Eyes (≈4.76mm)**: Slightly smaller than 5mm, these eyes are ideal for more delicate patterns, like nymphs and smaller baitfish imitations. They provide a balanced profile without overwhelming the fly.
The **FLAT RED** finish adds an extra layer of attraction, mimicking the natural eye color of many baitfish, which can trigger predatory strikes.
## **Key Factors to Consider When Choosing Eyes**
### **1. Fly Size and Weight**
The size of your fly will dictate which eyes are best. Larger flies (3” and above) benefit from **5mm eyes**, as they add weight for better casting and stability in the water. Smaller flies (1-2.5”) pair well with **3/16″ eyes**, maintaining a natural profile while still providing flash.
### **2. Water Conditions**
– **Clear Water**: Smaller eyes (3/16″) blend naturally, preventing spooking wary fish.
– **Stained/Murky Water**: Larger, brighter eyes (5mm FLAT RED) enhance visibility, helping fish locate your fly.
### **3. Target Species**
– **Trout & Panfish**: 3/16″ eyes work well for subtle presentations.
– **Bass & Pike**: 5mm eyes add bulk and flash, increasing strike triggers.
– **Saltwater Species**: Larger eyes (5mm) help flies stand out in deep or turbulent water.

## **Final Recommendation**
If you’re tying **larger, flashier patterns** (streamers, poppers, saltwater flies), go with **5mm eyes** for maximum visibility and weight. For **smaller, more natural imitations** (nymphs, emergers, small baitfish), **3/16″ eyes** provide a subtle yet effective profile.
No matter your choice, the **FLAT RED finish** enhances realism and attraction, making these eyes a must-have in any fly tyer’s toolkit.
