Pigments present in cones of retina are connected with

Options

A. Night blindness
B. Accommodation of eye
C. Colour discrimination
D. Imeage formation.

Answer

To answer the question regarding the pigments present in the cones of the retina, we can follow these steps:

### Step 1: Understand the Types of Photoreceptor Cells
The retina contains two main types of photoreceptor cells: rods and cones. Rods are responsible for vision in low light conditions (scotopic vision), while cones are responsible for color vision and function best in bright light.

**Hint:** Remember the two types of photoreceptors: rods for low light and cones for color.

### Step 2: Identify the Pigments in Cones
Cones contain specific pigments known as iodopsin (or photopsin). These pigments are crucial for the perception of color.

**Hint:** Focus on the name of the pigment associated with cones.

### Step 3: Connect Pigments to Their Function
The primary function of the pigments in cones is to facilitate color discrimination. This means that cones allow us to see and differentiate between various colors.

**Hint:** Think about what cones enable us to do in terms of vision.

### Step 4: Eliminate Other Options
The question provides multiple choices: night blindness, accommodation of the eye, color discrimination, or image formation. Since rods are associated with night vision (night blindness) and the overall function of the eye involves more than just cones, the most accurate connection for the pigments in cones is color discrimination.

**Hint:** Consider what each option specifically relates to in terms of vision.

### Conclusion
Based on the above steps, the pigments present in the cones of the retina are connected with color discrimination.

**Final Answer:** Color discrimination (Option C).
