Eye health warning as exam season starts

As Exeter students pore over textbooks and stare at computer screens in preparations for exams, a leading eye expert has warned young people about the risks of eye strain.

Intensive revision may help boost grades but according to Mesha Tanna, Senior Optometrist with Optical Express, it can also trigger a range of health problems including headaches, blurred vision and pain in the neck, shoulders and back.

Mesha said: “While it is admirable that so many young people study hard to get good results in their exams it is crucial that they do not overlook the importance of caring for their eyes.

“According to research, almost a third* of university students suffer from eye strain. Symptoms of eye strain include headaches, blurred vision, difficulty focusing, gritty eyes and increased sensitivity to light.”

Mesha recommends that students sit at a comfortable workstation, take plenty of breaks and blink frequently to keep their eyes lubricated.

She said: “Students who focus intensely on screens and text books for a significant period of time are at risk of pseudomyopia – a temporary form of short-sightedness which causes blurry distance vision and can last for several days.

“The best form of prevention is looking into the distance regularly to give eyes a rest. However, it can become a chronic problem so students should consult an optician if symptoms persist for more than a day.”

With increasing evidence about the dangers of over exposure to the blue light emitted by computer screens, tablets and smart phones Mesha advises that students consider wearing corrective lenses.  Optical Express stocks Neva Max Blue UV glasses which filter out the harmful component in blue light and also provide UV protection.

“Exposure to digital devices can damage retinal cells and is linked to age related macular degeneration (AMD) – a leading cause of blindness,” Mesha said. “If viewed before bedtime the glow from these devices can also upset your sleeping pattern as the hormone responsible for prompting tiredness, melatonin, is reduced.”

Mesha also recommends that students who already require vision correction ensure their glasses or contact lenses are the correct prescription and are suitable for extended periods of near work.

She concluded: “If you experience headaches, discomfort or are in any way worried about your eyesight consult an optician.”

It is recommended that most people have an eye test every two years.
