After a sight scare in June had an emergency eye test with long standing opticians Specsavers. Results fine with little change from previous year. Three months later had another test at Specsavers since long distance sight was blurry and night driving hazardous. Test told an apparently different story - signs of cataracts, mention of Glucoma monitoring and sight changed in both eyes by 1.00 point. This change was in just three months, which coincided with starting pred. Specsavers optician assumed changes were probably pred induced.
Since this change had apparently happened so quickly, didn't rush to order new glasses as I wanted to see if there was any further change over next couple of months before spending £350!
Last week decided impromptu to have another test, this time at Tesco. Once tested I showed the new optician at Tesco my new prescription from Specsavers. He asked to check the prescription from my current glasses as well.
When he came back he changed the testing lenses so that, in succession, I tried current lenses, newly prescribed lenses from Specsavers and lenses he prescribed. The difference was phenomenal! With the new prescription from Specsavers I could only see 50% of what I could see with the Tesco lenses. Why???????
Because both current glasses prescription and new Specsavers prescription were too strong. The new Tesco prescription is weaker than I have had for three years with Specsavers!
So I can only conclude that either my sight has improved whilst I have been on pred or Specsavers got it wrong - twice!
In respect of cataracts and worries over rising indicators towards Glucoma, which obviously concerned me and may have forced my hand to try to taper pred levels more quickly, the new optician compared the three year record I had obtained from Specsavers and the results from the tests he had done. He told me that over the three years there had not been any significant change and assured me I had nothing to worry about at present.
So........ It is definitely worth getting a second opinion.
