Factors maintaining Transparency of Lens

Lens is transparent structure. disturbance in transparency of lens leads to disease known as cataract, which will be discussed in another posts.

Here , we ought to discuss the factors which are responsible for maintenance of transparency of of lens briefly ..

Factors which contribute to its transparency are as follows

# Avascularity

#Tightly packed nature of lens cells

# Narrow membranes of lens fibres

#Loss of organelles of cells

#Arrangement of lens proteins

#Semi-permeable character of lens capsule

#pump mechanism of lens fibre membranes

this mechanism maintains the electrolyte balance and thus maintains a relative state of dehydration inside the lens.

# Auto oxidation and high concentration of reduced glutathione in lens —-> leads to lens proteins in reduced state. which maintains its transparency.
