The importance of good lighting

Small changes to lighting can make big differences to people's lives but lack of information, and caution about electrical works, can mean that practical lighting guidance is rarely provided.

Compared to other people, people with visual impairments often need more light to see clearly. People aged over 60 need three times more light than people under 20. Lighting needs are affected by eye condition, ageing of the eye, lifestyles and preferences. For most people, more light and less glare make the most of sight and lighting.
  • 1 in 8 people aged over 75 have serious sight loss; more have failing sight
  • 2 million people in the UK have low vision affecting their performance of everyday tasks
  • 65,000 people in the UK are diagnosed with low vision each year
  • eye conditions that limit sight include macular degeneration, retinitis pigmentosa, glaucoma, diabetic retinopathy and cataracts
  • with age, changes to the eye increase sensitivity to glare, difficulty of adapting to changing light levels, and make contrast and colour harder to discern.
In the "7 Easy Ways to Take Care of Your Eye's Health" one of them is about lighting, "Lighting is really important to maintain your eyes health. Working with low lighting may cause your eyes easily tired. Too much light is not also good." That's why we need to love our eye by design a good lighting.

Good lighting generally involves:
  • more light (except for people with photophobia)
  • less glare
  • independent switches and dimmer switches that can adjust light levels for individual needs
  • more and better colour contrasts
  • consistent light levels across and between rooms.
Good lighting is simple to arrange, generally low cost and always cost effective in reducing risks and increasing independence.

However, we mustn’t forget that aesthetic elements in our room are also important when we’re designing a good lighting system in a room. There are various alternatives we can try to use is by using good lamps, like ones such as Carmen Collections, "forecast lighting" for wall lamps positioned near a reading desk. It can be combined with "fine art lamp" from Fontana Bella Collection. With these lamps we can have a good lighting system.
