Using a hand lens will not only make it easier to identify plants such as lichens, but you’ll also be able to see the beautiful, intricate structures on a plant which are not easily visible to the naked eye. 

A hand lens is a pocket-sized magnifier, which you can pick up from your favourite natural history or ecology suppliers to kick start your botanical explorations. When looking for your new hand lens, start with one with x10 magnification, and expect to spend £10-£20. 

How to use a hand lens 

Hand lenses are not used in the same way as a traditional magnifying glass but are held close to the eye. Here’s how to do it:

1. If you are right-handed, hold the lens in your right hand as close as you can to your right eye (and vice versa for left-handers). If you wear glasses, you can take them off or not – whatever is the most comfortable.

2. Hold the plant between the thumb and forefinger of your other hand and bring it very close to the lens until it comes into sharp focus. Don’t move the lens.

3. Always try to have contact between the hand holding the lens and your cheek, as well as between your left hand and your right hand. This gives you maximum control and allows you to keep the plant and lens steady. With practice this will become easier and easier, and you’ll find you can do it without shutting your other eye.

Now wonder at the marvels of even our smallest wild plants and fungi, and discover the hidden botanical world around you!
