I guess that means I not only have a hearing disability, I also have a vision disability.
My hearing on my left side is partially corrected with my Osia Bone Conduction Hearing Aid, but not 100%. We haven’t measured the percentage of correction, but I wool estimate it to be at 80%.
My vision is primarily defined by a disease called Keratoconus. I have it in both eyes, but to a greater extent in the left eye. It is barely measurable in my right eye. It’s odd that the left ear has an idiopathic loss of hearing, and the left eye is affected by the Keratoconus. It almost makes me think something happened to me somewhere along the way that primarily affected the left side of my head.
At any rate, the Keratoconus, which I will from here on refer to as KC, is characterizecd by the cornea of the eye developing a thin surface allowing the internal pressures of the eye to push outward in irregular patterns causing the surface of the cornea to take on the appearance of one or more cone shaped protrusions. This causes the cornea to refract light so that multiple images of the same thing show up in the subject’s.
KC cannot be corrected by glasses, nor can it be corrected by conventional contact lenses. KC can only be corrected by wearing large Rigid Gas Permeable lenses that are large enough to cover the entire cornea without resting on the cornea. No part of the lens can touch the cone formed by the KC because it will cause it would result in intense pain. These lenses are referred to as scleral contacts because the skirt of these lenses rest on the sclera of the eye, which is the white part of the eye. The sclera has very little feeling, which allows this lens to work.
Scleral lenses are not 100% effective in correcting KC in all patients. In my case they correct my vision to 20/25, which in effect is close enough to be considered perfect. However, I can’t wear them every day. My eyes are prone to dryness, which causes the lenses to become very uncomfortable. On those days my vision without corrective lenses is 20/100. It’s good enough to get around, I even drive in families areas during daylight, but not at night.
So with my hearing, and my vision, I guess I have two disabilities. It’s interesting that until I read this thread, I didn’t consider myself disabled.
