diminished quality of vision straylight
Conditions
Interventions
Patients with dry eyes will undergo the following examinations:
1) documenting subjective complaints of reduced visual quality
2) measurement of best corrected visual acuity
3) straylight measurement
the visual effect will be measured with straylight measurements performed just
before the use of coffee creamer and during the 'wash out'-period
- with the use of an eyelid speculum the tear break-up
the
visual effect of this lengthened tear break-up time will be measured with
straylight measurements peformed at regular intervals during the time the
eyelid speculum is in situ.
