"possible misdiagnosis of high eye ball pressure"

At CHEC slough, I had what seemed a cursory check on my eye ball pressure. The optician used a pipet to blow air on to my eyeballs just once each time and based on visual observation from that, diagnosed I had high eye pressure and I needed to take Monopost eye drops for the rest of my life. Later during a routine eye test at Windsor Vision Express, they used a big machine to do several puffs of air and diagnosed me with normal eye ball pressure. I then arranged a test at CHEC Battersea in November 2024 and they used a hand held device to give my multiple puffs of air in less than a second. The optician said I had normal eye ball pressure, and he also said 2 tests of eye ball pressure spread over several days should be done before diagnosing high eye ball pressure.
