I am a person with multiple disabilities: cerebral palsy and deaf/hard of hearing. Even though this is not considered as a disability, I am also nearsighted and always had to wear glasses. What I write here is not to be offensive, but to share what it feels like to be partly deaf blind in my own experience.
After four and a half years of having glasses, its life came to an end. The frame broke when I was cleaning lenses after swimming in the pool. Even with someone talking about me getting a consultation for LASIK (laser surgery for eyes) and a temporary fix not working out, I began to declare myself as partly deaf blind. I am 100% deaf, but without glasses, I feel like I am blind because everything is a complete blur. To have to deal with five days without glasses was extremely difficult to deal with as a deaf individual because of being so reliant on lip reading and reading off captions when watching TV and movies.
Here are some issues of being partly deaf blind.
Feeling incomplete.
With wearing glasses on an everyday basis, from the moment you wake up until you get ready for bed, having glasses on your face completes your everyday look. Despite all of the struggles that exists while wearing glasses, you don't feel complete without glasses. In the days of being partly deaf blind, it definitely did not feel complete without having any glasses.
Being completely unsure of what is going on.
With glasses, you can be so sure of what is going on. Everything would become a blur without glasses. If you are deaf, then it will be a tough couple of days being partly deaf blind. Even if you went to a store to buy glasses 24 hours after your glasses broke, you would still have to wait a certain amount of days. With the wait, it is extremely difficult to follow conversation and what is going on at any moment
Migraines.
Migraines are excruciating headaches from Satan. If you are going to have to deal without glasses prepare yourself for a lot of headaches/migraines (and get Excedrin). Pains will come if you are so used to wearing glasses every day, but not having any glasses can be extremely stressful. It's a disaster if you are deaf/hard of hearing since extra straining and trying even harder to understand what is going on will be extra stressful.
Accessibility.
There are technologies, nowadays, that can change settings to be more accessible. Without any glasses, settings can be changed for the text to look bigger and it would make it easier to see until getting new glasses. Unfortunately, TV does not have any setting to make captioning appear larger that you would practically have to be close to the TV screen.
Temporary fix.
When considering a temporary fix, it only works temporarily. With my glasses, they broke on a Sunday night and clear polish was applied. It broke, and then marine glue (strong glue ideal for repairs) was used twice; marine glue was used twice because my glasses broke the first time it was applied. I would not use marine glue for glasses because it smells, and it's not that strong to fix glasses.
