Temp change/lens fogging

Allmost embarrassed to ask but recently found condensation forming inside my lenses shortly after going out in the cold. I keep desicant pcks in my pelican case but moisture still formed inside the lens. Suggestions?

I always find it disperses on it's own, but my situation is somewhat different in that I take equipment from cold to warm.

I think there is nothing actually you can do to prevent it if there is an abrupt temperature change.
It also happens to camera mirror and sensor and not just the lens 'coz glass is affected by this temp change.
Even on the manual it just states that give it some time and it will dissipate on its own.

Let me assume that it happens when you bring the lens/camera back into the warm from the cold. The condensation happens because the lens is below the dew point on the air in the house and moisture begins to condense. The only way I know of to prevent it is to store the lens in air that is dryer than the air in the house. The way I sometimes do this is to put my camera and lens in a zip lock bag that I take with me outside. It will have the same dry air as from outside in it and will prevent the camera from being exposed to the moist air inside my house until it warms above the dew point. The bag doesn't completely eliminate the condensation every time but does help.

I agree with DonP. I usually use a ziplock bag, too.

When I lived in Hawai'i, our house had no heat, AC or insulation, and the windows were nearly always open. So the inside air was always pretty much the same temperature as the outside. I can report that completely eliminates lens fogging.

You are going from dry cool air conditioned to warm and humid.
Once the temps equalize, the problem goes away.
The way to keep it from happening is to acclimatize the equipment, which means putting it in a zilploc bag or wrapping it in a towel or leaving the case closed or whatever until the temps have had a chance to equalize.
You want to let the temperature of the equipment equalize in the dryer air.
If you can safely leave your camera gear in a non air conditioned garage, that is best.
