  • Research carried out by Optometrist Geoff Shayler in 2002 at a school in Bournemouth, Dorset indicated a direct link between the range of clear, near focus and educational ability as defined by their SAT results, the smaller the range, the poorer the SAT score. In addition this study also showed a link between these ranges and their behaviour in school.

    This simple Vision test for parents requires just two basic measures

    Take a piece of small news print, start with print about 25 cm from your child’s face, can your child see it clearly?,[if not try moving in or out a bit to see if you can find a distance when it is clear. If blurred at all distances then child definitely has a viison problem], move the print slowly in until your child just starts to find the print blurred (gets difficult to read) measure distance from forehead to print (NP). Now move the print away from the face until it just starts to blur (gets difficult to read). measure this distance (FP). Divide FP by NP. i.e if. NP=10cm, FP=30cm, then the FP/NP ration is 30/10 =3. If FP/NP ratio is <3.5, your child has a visual processing problem, Between 3.5 and 4.5, may have a visual problem. >4.5 unlikely to have a “visual” problem but may still have a “sight” problem – i.e.  if short-sighted will need specs to see clearly in the distance

    In assocation with Optometrist  Smita Trivedi in London, we identified that around 80% of children achieving grades w – 1 in their Key stage 1 SATs had an FP/NP ratio <3.5 whereas only 10% of grade 3 children were within this range

    This test is NOT a test of sight, which is more dependent on the ability to read a distance letter chart

    A full eye examination is recommended for all children at a qualified optometrist and a basic NHS test is free for all children under 19 in full time education
