Written answer: Axis rotation in a toric contact lens

My left eye glasses prescription is SPH -3.75 CYL -1.00 AXIS 65.0. My left eye Contact lens prescription is SPH -3.50 CYL -0.75 AXIS 70.

My question is whether or not the AXIS is correct in the contact lens. My vision in it is nice and sharp and I can see the smallest of letters in the distance no problem but when I blink the vision goes slightly blurred for about 2 seconds then returns to normal. Also the vision will go slightly blurred just every now and again then returns to normal but my right toric lens doesn’t go blurred at all, even when I blink so I was wondering if it is normal for this to happen? It’s not too much of a problem but was wondering why the right lens remains perfect all the time and the left has this slight blurring issue. Would a 60 AXIS stop the blurring?

Written answer: Pin hole test?

I was at the eye specialist today and they asked me to read the Snellen chart with my glasses on, I could only read so far down. They placed a pin hole lens in front of me and it made things slightly sharper. What is the idea of pin hole lenses and how do they work? Why did the eye specialist not put stronger lenses for me to see better, after all I have not seen anyone walk around with pin hole glasses before. I have really bad eyesight any way.

My Specsavers prescription does not specify a Near Addition. It looks as if it has Sph/Cyl/Axis also on the Near line

e.g.

Right Sph Cyl Axis left Sph Cyl Axis

+2.00 -0.25 80.00 Near +0.75 -0.50 110.0

Written answer: Headaches and difficulty focusing on the computer screen

I’ve been having frequent headaches and occasional difficulty focusing on the computer screen recently, particularly when tired. I had an eye test today, which the optician said was all fine (R +0.25, L+0.00). She referred me to a second woman who ran a peripheral vision test, which I was again told was fine. However, the woman who ran the peripheral vision test said it would be worth getting a prescription free or very low prescription pair of glasses with anti-glare coating to reduce the headaches and eye strain.

I am 33 years old and have worn daily contact lenses since age 15 and also glasses.
