Following an assessment you should advise the patient, on: 

• their visual function relating to visual acuity and contrast sensitivity levels; you:
  • should explain this to the patient in relation to both threshold and sustained visual function
  • should differentiate between clinical measurements and practical ability
  • may need to demonstrate how to make adaptations to every day practical tasks such as reading door signs, mobile phone screens, newspapers, timetables and packets 
• illumination as well as the use of specific tints and glare shields and non-optical devices
• the effects of the condition affecting their vision
• the benefits and disadvantages of low vision devices.

You should know where to direct people for information on support services. You may wish to provide information on:

1. the most common eye conditions that cause low vision
2. accessing eye care liaison Officers (ECLO’s) or equivalents 
3. support services, such as talking books, holidays, safety at home, lighting and travel.

You should be aware of the impact sight loss may have on people who have other sensory, physical or intellectual impairment.
