Having spectral sensitivity, I constantly feel that my vision is compromised. I have tried working with coloured tints but find that a pair of tints only works for a short time. When the light changes, they no longer work. This year I had not tints that worked from July to September so I decided to return to considering my prescription glasses.
Over the years I have been to the optician’s and have received a number of different prescriptions. I decided to scrutinise these. One said I have astigmatism in my left eye, another in my right, another in both eyes. Opticians have disagreed over the severity of my astigmatism and then one optician identified a squint. I looked at my prescriptions and wondered what I should do.
I had noticed previously that when when I wore glasses, the shape the frames made always felt like a rectangle going smaller over my right eye. I wondered why this was but guessed it was just the best I could do with glasses. However now since reconsidering, I feel pretty sure this happens when my squint comes into operation. Next I thought about my astigmatism. I like working with charts on my computer which are always in grids, and it is obvious when my astigmatism is a problem. I can no longer manage the grids.
My astigmatism and squint symptoms are definitely seasonal. They change with the changing light. So I decided to observe my symptoms as the year progresses, create my own prescriptions and buy cheap experimental glasses online.
So far I bought some glasses for my astigmatism in September (0.25 strength in both eyes) and they worked! Then they stopped working at the end of September and I had no glasses again. I happened to have another pair with a 0.25 in one lens so I played around with 0.5 strength by covering my eye with 2 lenses at the same time. I could see this was good so I bought a pair of 0.5’s. They are working into October in the mornings. Once the light gets brighter around lunch time, I need something else. I dared to buy some low strength astigmatism glasses with a prism (as prescribed by one of my opticians). These work great when the light is bright. In fact, I am wearing them now and my binocular vision is so good that I am able to write a blog post in October. Previously I haven’t been able to do this.
As the year develops, I will continue to observe my vision and prescribe myself any other glasses I think I need.
When my vision is compromised, I struggle with focus, tracking and scanning between distances. I have very good visual acuity and these symptoms are all very subtle. However, due to my sensitivity, these symptoms are enough to stop me in my tracks! I struggle to focus on daily activities, I struggle to read comfortably and to plan ahead, and I struggle to think outside of the box, analyse, assess and see things from another’s perspective. I feel like I am stuck, living only in one dimension and unable to move.
Have seasonal eye-checks, even just one in the summer and one in the winter, and you might be surprised by what you find. Alternatively, monitor your symptoms and prescribe your own glasses!
