# **How to Choose 24 FLAT GLOW IN THE DARK 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. **KyleBooker’s 24 FLAT GLOW IN THE DARK 5mm or 3/16″ Eyes** are a top choice for anglers looking to enhance their fly patterns with visibility and realism. But how do you decide between the two sizes? In this guide, we’ll break down the key factors to consider when choosing the perfect eyes for your next fly tying project.
## **Why Use Glow-in-the-Dark Eyes?**
Glow-in-the-dark eyes are a game-changer for fly fishing, especially in low-light conditions. These eyes absorb light during the day and emit a soft glow underwater, making your lures more visible to predatory fish like bass, trout, and pike. **KyleBooker’s glow-in-the-dark eyes** are designed to last, ensuring your flies stay effective even after multiple casts.
## **5mm vs. 3/16″ – Which Size Should You Choose?**
Both sizes—**5mm and 3/16″ (approximately 4.76mm)**—are popular in fly tying, but their best applications differ slightly.
### **1. 5mm Eyes – Best for Larger Flies**
– **Ideal for streamers, saltwater flies, and bass bugs**
– Provides a more pronounced profile, increasing visibility in murky water
– Works well on patterns like **Clouser Minnows, Woolly Buggers, and Deceivers**
– Better for targeting **larger fish species** that rely on visual cues
### **2. 3/16″ (4.76mm) Eyes – Best for Versatility**
– **Perfect for medium-sized nymphs, wet flies, and smaller streamers**
– Offers a subtle yet effective glow without overpowering the fly
– Great for **trout, panfish, and smaller bass patterns**
– Works well on **balanced leeches, sculpins, and crayfish imitations**
## **Key Factors to Consider When Choosing Eyes**
### **1. Fly Size & Target Species**
– **Bigger flies (3-5 inches+)** → **5mm eyes**
– **Small to medium flies (1-3 inches)** → **3/16″ eyes**
### **2. Water Conditions**
– **Murky or stained water** → Larger eyes (5mm) for better visibility
– **Clear water** → Smaller eyes (3/16″) for a more natural look
### **3. Depth & Light Penetration**
– **Deeper water or night fishing** → Glow-in-the-dark eyes perform best
– **Shallow or bright conditions** → Smaller eyes may be sufficient
## **How to Attach KyleBooker’s Glow-in-the-Dark Eyes**
1. **Clean the Fly Head** – Ensure the surface is free of excess thread or glue.
2. **Apply a Small Drop of Super Glue or UV Resin** – This secures the eyes in place.
3. **Press Firmly and Hold for a Few Seconds** – Prevents shifting while drying.
4. **Coat with a Thin Layer of Epoxy (Optional)** – Adds durability for long-lasting use.
## **Final Thoughts**
Choosing between **5mm and 3/16″ glow-in-the-dark eyes** depends on your fly pattern, target species, and fishing conditions. **KyleBooker’s high-quality eyes** ensure your lures stand out in any environment, increasing your chances of a successful catch.
For anglers who tie a variety of flies, keeping both sizes in your tying kit is a smart move. Experiment with different patterns and see which eyes produce the best results on the water!
