Answer 2

Answer:  

Cockroaches do possess blurred vision.   Cockroaches have compound eyes along with simple ones, that enable them a complete 360 degrees vision. However, due to their compound anatomy, they have limited sight and the vision is blurry. They have a near-perfect vision in low light but cannot see optimally in red light. The vision gets blurred as the image is formed consisting of more than thousands of individual images.
