In the last 3 - 4 weeks my visual focus has changed somewhat. When I concentrate my vision on something, after a few seconds my focus will drop of a little and then clear up. Written text is not as sharp anymore and will alter from being sharp to very slightly blurry and back again. My eyes feel painful, tired and dry at times also.

Dryness can cause blurring of the vision along with discomfort. It would be sensible for you to make an appointment with your local Optician who will be able to check your vision and assess if any spectacles are required. The Optician will also assess the health of the eye and will be able to advise you if your eyes are dry and if so will advise you of any necessary treatments.
