Everyday life and glasses

Technology - Using computers, mobile phones or watching TV

The use of computers, mobile phones and tablets is increasing, as well as the amount of time we spend staring at screens or watching television, sometimes we are even exposed to different screens at the same time. In 2005, 72 point carried out a report called ‘Square Eyed Britain’ on 2,750 office workers. This report found that 90% of workers regularly suffer from ‘screen fatigue’ (headaches, sore or tired eyes, trouble seeing colours and blurred vision).

Remember that if you work with display screen equipment (DSE), your employer may have to help towards the cost of your eye care.

Sun - Exposure to UV light

It is important to protect your eyes from the sun. If your eyes have been exposed to too much UV light, as a consequence you may suffer from photokeratitis. Your eyes will look red and will water, and it might also feel like you have dust in them. Photokeratitis usually gets better by itself within a few days, but it could cause some long-term problems. This eye condition is sometimes referred to as 'snow blindness'.

When being exposed to UV light it is always recommended to wear sunglasses, especially around midday when levels of UV light are higher. Be careful when choosing sunglasses. If you don’t get 100% UV protection, harmful rays from the sun will still reach your eyes through the sunglasses, increasing the risk of damage. Sunglasses that wrap around your eyes will give the best protection as they cover more of your eyes, so there is less chance of sunlight, wind and pollen getting into them.

Driving - Dangers of driving

Drivers must wear glasses or contact lenses when driving if it's necessary to meet the standards of vision for driving. The Driver and Vehicle Licensing Agency (DVLA) has set rules for driving: the driver must be able to read a number plate made after the 1st September 2001 from 20 metres away, must also meet the minimum eyesight standard requirements for driving and have an adequate field of vision. Find out more about driving eyesight rules . It is illegal to drive if the standards of vision for driving are not met.

Another thing to keep in mind is to never replace your prescription glasses with a pair of normal sunglasses if it's sunny and you are driving. You can opt for a pair of prescription sunglasses instead; it's also advisable to always keep a spare pair of prescription glasses in the car.

You must also be aware of the dangers of tinted glasses. Under the Highway Code, you are not allowed to wear tinted glasses, lenses and visors at night, in poor light or poor visibility, as they can affect or restrict your vision.
