You'd be surprised just how many kids can't focus properly when the focal length is relatively short. Generally one eye focus and the other one "Wanders".

Your eyes don't focus well at a particular focal distance (x). 2. Your screen is at distance x, so it is hard to read because it is not very clear due to 1. 3a. You get reading glasses so your eyes can focus at that distance or 3b. You increase the font so the reduced focus is "non-breaking" - your brain doesn't care that the edges of the letters are not in focus because there is enough for it to interpret. Both 3a and 3b produce the desired result - you can read the page. My preference would be for the glasses - reduces the need for the brain to interpret and ignore, treats the problem not the symptom. The key take-away from this discussion is that you should let your children sit as close to the TV as possible to reduce their eye strain and potential need to wear glasses in the future. -- David Connors (da...@codify.com) Software Engineer Codify Pty Ltd - www.codify.com Phone: +61 (7) 3210 6268 | Facsimile: +61 (7) 3210 6269 | Mobile: +61 417 189 363 V-Card: https://www.codify.com/cards/davidconnors Address Info: https://www.codify.com/contact ************************************************************************************************************************ This email (including all attachments) is confidential, may contain personal or legally privileged information and is intended solely for the named addressee.
