A good example as to why Specs2U insists on in-depth 30 minute eye tests for all our customers. A lady came in for a routine eye test today. Her pressures were fine. The fields test for periphery vision was passed with flying colours. But our optom thought there was something else not quite right (following a prolonged session with slit-lamp and Volk lens to check all around the inside of the eye). The digital photograph confirmed it. The very early signs of glaucoma were identified with the blood vessels around the optic nerve. As a result the lady has a much earlier notice of this serious condition and by catching it so early it will hopefully mean faster treatment. We do 30 minute tests as standard for just this reason.
