I went for my first eye test today for about 8 years. My eye sight as been terrible lately so I bit the bullet and made an appointment. To my surprise, the optician said I have perfect eye sight and all the lenses she tried made my sight worse. She suggested that maybe I'm spending too much time in front of a computer screen without breaks and getting too tired. With a 5 week old baby and a job which involves sitting in front of a computer all day there's a good chance she's right.
