Reading Ability and Coloured filters

[Anna Mason]

I just wondered if anyone was aware of any research into coloured lenses for improving vision.
I suffer from a lot of ghosting and double vision so although generally my vision is good I have a devil of a time reading black on white writing and can never work out what my reading distance should be. As some of the problem is caused by glare I wondered if anyone has actually looked into this or am I completely off my trolley ?

Not off your trolley at all, Anna.

A lot of work has been done on the way in which coloured filters improves vision for reading: sometimes people have bespoke glasses made with different colours in each lens.

Much of the early work was done on children and adults with dyslexia, but the effect has been shown to have a more general application.

I think that if you look for Irien Syndrome on the www you will find a good starting place for your research.

With RGP lenses my dyslexia improved as the tint was slightly different in each lens. Now I'm on the K3 lenses, if I need to read an improtant document for work I put on my sunglasses which I had made with a tint specific to my needs. To most they looklike ordinary tinted prescription glasses but there is no power in the lens.

Prior to the KC when I was wearing normal glasses, rather than switch between different glasses all the time I made up my own A4 cover page from car windscreen tinted film. It gives everything a bluish tinge and makes reading far less stresful on they eye. For PC work I have adjusted the monitor colours to have a bias toward blue by turning down the red and green components. Most flat screen monitors alow you to do this without changing and of the computer settings.

Very useful thanks

I often use coloured polypockets(open sided ones) when I'm reading black print on white paper, to avoid the glare.
Thats is an inexpensive suggestion to try first. Pupils with dyslexia in my school also use coloured polypockets or special tinted film which just does the same job.

My real problem at work is a new laptop which has a mirror like screen. It is a nightmare for glare.Changing the tint or colours in the screen would make no difference.It is the screen surface. I'll need an anti glare cover to put over the laptop screen.Anybody buying a new laptop beware, and choose a matt type screen if you are sensitive to light/glare.
