Corrective tablet screens good news for some

By August 1, 2014No Comments

Another BBC article that caught my attention this week, this time about a VDU that can correct vision problems to negate the need for glasses or contact lenses. In short, because it is very technical, the technology is powered by software and algorithms that change the light that a screen emits to distort the image a user sees to their prescription.

When the article talks about one in three people suffering from some form of myopia (short-sightedness), the fact is the vast majority of these people need corrective lenses or glasses for more than just using a tablet. For these people this piece of technology is unlikely to be of any use.

However, there is a very small group who could find this technology hugely beneficial. Even with the most sophisticated contact lenses or glasses, some people with conditions such as keratoconus still see halos and ghosting when looking at VDUs. My hope is that it is that this group that may benefit from this specialist technology. Keratoconus can affect people from a relatively young age, people for whom computers an integral part of their lives both in the work place and at home, so hopefully for this group, this technology could make a real difference.
