Annual eye tests!
I have my eyes checked every year without fail. Optometrists are very well trained to pick up all manner of health issues, that often show up in the eyes first, before the rest of the body protests.
So far, I have been referred to the hospital eye department on three separate occasions, each issue requiring between 1 and 2 years of monitoring before being discharged.
The same also applied to DB.
This time I mentioned that sometimes when watching tv, I feel as though I am blinking a lot to clear my vision. Tests appeared to show I may need glasses to watch tv (or buy a larger screen) as we sit nearly 15 feet away from it!
Anyhow, I chose cheap frames, dismissed all the extras (and their costs) as the glasses normally come free with any coatings I generally need. I will get one pair for reading and one for distance. Despite what I have said above, I am not sure the distance ones will help but we shall see.
All in all £52 due to special offers on at the time of my visit.
