VZUM™ AF-Lens
DELTA uses VZUM™ AF-LENS, a photochromatic lens that adapts itself to the intensity of the light present in the environment and automatically changes colour, shielding off harmful UV rays of any sort.
Their temporary transformation takes place in a short period of time but it is, nevertheless, gradual and independent of any atmospheric factors. The optical strain is therefore reduced to a minimum and the lenses remain active even on a cloudy day.
VZUM™ AF 鏡頭
DELTA 使用 VZUM™ AF-LENS，這是一種光致變色鏡片，可根據環境中的光線強度自行調整併自動改變顏色，從而屏蔽任何類型的有害紫外線。
它們的臨時轉變發生在很短的時間內，但它是漸進的，不受任何大氣因素的影響。因此，光學應變降至最低，即使在陰天，鏡片也能保持活性。
