Anti-Fog and Lens Cleaning
Anti-fog and lens cleaning products keep your view clear when cold air, breath and wet brush fog up an eyepiece at the worst moment. This category has three simple tools that fit in a jacket pocket.
What we carry
- Breakthrough Long Lasting Anti-Fog Gel. A gel you apply to the lens to resist condensation for longer than a quick wipe.
- Zeiss Anti-Fog Wipes and Lens Cleaning Pen. Pre-moistened wipes for quick fog protection in the field, plus a pen for spot cleaning.
- Optical Lens Cleaning 3 in 1 Pen. A compact pen for lifting dust and smudges off lenses.
Where fog comes from
Fog forms when a cold lens meets warm, moist air, like your breath on a cold eyepiece or a scope carried from a heated truck into the night. An eyecup that seals well helps, and so does letting your optics cool to the outside temperature before the hunt starts.
A word on thermal objective lenses: they are coated germanium, not regular glass, so follow your optic maker's cleaning guidance before using any product on the front lens. Use these on eyepieces and glass optics unless your manufacturer approves them for the objective. When in doubt, a soft brush and a dry lens cloth are the gentlest start.
Pair them with a fresh eyecup from our eye cups and lens caps category, where you'll find shutter eyecups that keep the screen's light in.
Frequently Asked Questions
Do anti-fog lens wipes actually work?
They do, for a while. An anti-fog wipe leaves a thin film on the lens that stops moisture from beading into fog, and it lasts until it wears off or gets wiped away. The Zeiss wipes here ride easily in a pocket for a quick reapply. For longer protection between coats, a gel like Breakthrough's holds up better.
What is the best anti-fog lens cleaner?
Pick by how you hunt. If you want something quick, pre-moistened wipes like the Zeiss Anti-Fog Wipes clean and treat in one step. If you sit for hours in damp cold, Breakthrough Long Lasting Anti-Fog Gel is made to last longer. Keep a lens pen handy for dust and smudges.
How do you stop scope lenses from fogging up?
Let your optics adjust to the outside temperature before you need them, rather than carrying them straight from a warm truck to the stand. Keep your breath away from the eyepiece, use a sealing eyecup, and treat the eyepiece glass with an anti-fog product ahead of time. Store gear somewhere cool overnight.
Does Dawn dish soap prevent fogging?
A thin film of dish soap can reduce fog on eyeglasses, but it streaks easily and isn't made for coated optical lenses. On a scope or thermal optic, use a product made for optics and check your manufacturer's guidance first. The coatings on good lenses are worth protecting from household cleaners.
