Final answer:
Seeking assistance and support to cope with vision loss is important for clients with glaucoma and significant eye damage.
Step-by-step explanation:
The client with glaucoma who has suffered significant eye damage would benefit from seeking assistance and support to cope with the vision loss. Option 4: "I will seek assistance and support to cope with the vision loss" is the correct choice. While relying on peripheral vision (option 1) and using a white cane for mobility (option 2) can be helpful, seeking assistance and support will provide the client with the necessary tools and resources to adapt and manage their impaired vision.
