入排标准
- 性别
- All
入选标准
- •1. Registered, returning customers attending the optometry practice for a routine, full NHS or private eye examination, during the trial period
- •2. Aged betwen 13 and 45 years
- •3. Visual acuity (VA) in each eye better than 0.1 logarithm of the minimum angle of resolution (6/7.5) as determined from their previous records or during the eye examination
排除标准
- •1. New customers attending the optometry practice for the first time
- •2. Patients attending for any other kind of optometric appointment other than a full eye examination
- •3. Those requiring significant adaptions to the standard subjective refraction process used in the eye examination, due to mental capacity/language. This includes the need to measure vision with picture or symbol charts rather than a letter chart
- •4. Individuals who do not exhibit normal binocular vision (ability for the two eyes to work together), including:
- •4.1. Subjects who report double vision as a symptom during the eye examination
- •4.2. Subjects who are found to have unstable binocular vision during the eye examination requiring the prescribing of exercises or prisms
- •4.3. Individuals with a history of lazy eye (amblyopia), suppression of vision in one eye and/or squint (turn in the eye) as recorded in their previous clinical records, or identified during the eye examination
- •5. Individuals with any ocular pathology or history of ocular surgery, including conditions known to affect the accuracy refraction measurements (media opacities)
- •6. Vulnerable subjects – will not be recruited on the basis that they would normally undergo a modified rather than the eye examination, adapted to meet their needs
