Explanation: 

Detailed explanation-1: -The stratum lucidum (Latin, ‘clear layer’) is a thin, clear layer of dead skin cells in the epidermis named for its translucent appearance under a microscope. It is readily visible by light microscopy only in areas of thick skin, which are found on the palms of the hands and the soles of the feet.

Detailed explanation-2: -Stratum lucidum is a thin, clear layer of dead skin cells in the epidermis of the skin. It is composed of five layers of dead flattened keratinocytes. These cells do not feature distinct boundaries and are filled with eleidin, an intermediate form of keratin.

Detailed explanation-3: -Its presence indicates the importance of having thicker skin to protect against frequent exposure to mechanical stress. The stratum lucidum is found in in between the stratum corneum and the stratum granulosum. The keratinocytes are filled with eleidin (a protein that may be later converted to keratin).

Detailed explanation-4: -The stratum lucidum is a thin, transparent layer of keratinocytes that are becoming less round and have a flatter shape. The top layer of the epidermis. This is the layer of the epidermis that you see.
