A good magnifying glass fire starter is a huge upgrade for a variety of survival kits. Sure, being able to start a fire with nothing but a lens is pretty darn cool, but there are also several advantages to having a magnifying glass handy. For starters, they are not consumable (meaning they don’t get used up, like matches, lighters, or ferro rods) and they are extremely versatile.
There are several options to consider when it comes to magnifying glass fire starters: lens material, focal length, durability, etc. This is where we come in. We’ve researched the best magnifying glasses, tested each of them, and now the results are in: the overall best, a lightweight budget option, and an upgrade option. If you need a magnifying glass that will add tons of versatility in a survival situation, one of our picks will keep your survival in focus.

What is a Magnifying Glass Fire Starter?
A magnifying glass is a unique way to be able to start a fire. It is just one of many methods that we touch on in our article:
16 Ways to Start a Fire Without Matches
A magnifying glass is a convex lens made from a transparent material. Usually, magnifying glasses are used to magnify images although they can magnify other things as well: namely, energy.
A magnifying glass fire starter is a magnifying glass that harnesses solar energy to light a fire. Both the diameter and the focal length are important since they must be close in order to effectively pinpoint this energy in a way that is useful for fire starting.
The type of magnifying glass is important since it rules out what can and can’t start a fire. For instance, if you are nearsighted, your glasses cannot help you start a fire since they will disperse the energy. If you are farsighted, however, then you are in luck. You could use your glasses in a pinch to focus the sun’s energy to a point and start a fire. If you have a low prescription, it may be more difficult though since your focal length will be pretty far away from the glasses, and hard to hold steady.
The most common materials that are used to start a fire optically are:
- Glass
- Plastics
- Water (and Ice!)
Many magnifying ‘glasses’ are actually made out of plastic. Plastic is usually cheaper to manufacture, but it is usually also harder to break. There are many different types of plastics, however, so plastic magnifying glasses can have a few drawbacks including:
- optical impurities (distortion and filtering)
- easy to scratch
- lower melting point than glass
Despite these drawbacks, a plastic lens is superior in a survival setting simply because it is less likely to break. A scratched lens is much easier to work with than a broken one. Plastic magnifying glasses are usually lighter weight, which can help when packing a bug out bag since every ounce can matter. The durability of a well-made polymer magnifying glass pushes it ahead of glass almost every time.
All that said, if you are exceedingly careful with your lens, a glass lens may produce better results with its clarity.
How to Use a Magnifying Glass Fire Starter
A magnifying glass is a versatile survival tool and makes for an excellent backup fire-starting solution. Using a magnifying glass as a fire starter can be more difficult than it seems. Several factors come into play that could derail your attempt:
- Weather – In order to start a fire with the sun, you need to harness solar energy with the sun in the sky. Cloud cover or rain will prevent this.
- Tinder – Bad tinder can ruin your chances of starting a fire before you even start. Make sure you have good, feathered, dry tinder.
- Magnifying Glass – We talked about how you can start a fire with many different things that magnify, but some materials are easier than others. Using ice to start a fire may be possible, but it is extremely difficult to do.
- Training – Learning the focal distance of your magnifying glass and how to focus the energy into a point may seem like common sense, but without practice, you may find it harder to accomplish in a survival scenario.
This video demonstrates very well how to use a magnifying glass fire starter:
You’ll notice in the video that she goes for the char-cloth for tinder, which is very forgiving and takes much less time to ignite. Even with the perfect conditions that we laid out above, one of the most important things you need to keep in mind is patience. A magnifying glass fire requires a steady hand, attention to detail, and plenty of time.
Who Needs a Magnifying Glass Fire Starter?
A magnifying glass can be a cheap, lightweight tool that boosts the functionality, versatility, and redundancy of a survival kit. The gear you carry is one of the most important factors in your preparedness. A magnifying glass is a smart tool to include in your:
- In-Place Survival Kit
- Bug Out Bag
- Get Home Bag
We even suggest considering it for:
Everyone should be familiar with these kits and have a disaster survival kit at the very least.
Why a Magnifying Glass?
Solar power, while not always reliable, is incredibly powerful. If the sun is out and you need to get a fire going- you can easily harness the energy to do so with just a small tool. A magnifying glass is an elegant solution. There are no moving parts to break. It doesn’t need electricity. Best of all: magnifying glasses are not consumable.
Using a magnifying glass to start a fire doesn’t leave you with any less potential to start a fire the next time. Matches, lighters, and even ferro rods eventually run out of strikes.
Magnifying glasses are versatile. You can use a magnifying glass to signal with pinpointed light. You can use it to see smaller objects and far away objects better. Magnifying glasses are often used with detailed maps. Some people even need them to see clearly, since they are the lenses in glasses.
Lastly, magnifying glasses are found everywhere. Even if you don’t follow our suggestion and add a magnifying glass to your survival kit, chances are that you have one around the house. If you bug out, there are magnifying glasses found everywhere. Some TVs are basically one giant fresnel lens. Take a look at this ingenuity by harnessing the power of the sun:
If that doesn’t get you excited about the potential of starting fires with a magnifying glass, I don’t know what will. As he demonstrates, your imagination is the limit when it comes to harnessing solar energy with lenses.
