How can I make sure my BigEye Lens doesn't fog during the dive?
Although Fantasea BigEye Lenses are assembled in a special lab, in which temperature, humidity and other relevant parameters are very carefully controlled, they can still fog up when submerged in water due to temperature differences.
Please note that it makes a very significant difference if the BigEye Lens is stored in a dry and cool place prior to the dive. For as long as you can prior to entering the water, you should keep the BigEye Lens (even with the housing it is installed on) in a dry, cool and shaded area. A padded bag with some Silica Gel Packs inside can serve as a perfect solution in this case. If this bag can be stored inside an air conditioned room prior to the dive, even better.
However, even if you don’t have a completely dry and cool place to store the lens in prior to entering the water and you BigEye Lens starts fogging up at the beginning of the dive due to temperature differences, please note that if you keep diving with it for about 10 minutes, the fog will completely disappear.
