1. If you've started having trouble with your vision, contact your eye care professional immediately. The earlier vision problems or eye diseases are diagnosed, the better your doctor will be able to help you. Typical symptoms include difficulty reading small print, reduced visual acuity, defective colour vision, sensitivity to glare, blurred vision or, more generally, severely limited vision.

2. The right visual device for you depends on the severity of the visual impairment. These can be prescribed by your ophthalmologist or fitted by your eye care professional. No matter your needs, the important thing is that the visual aid is individually fitted to the particular wearer. This is the only way to achieve optimum visual performance and good image quality with a maximum visual field.

3. Our eyes are typically used to always focusing on the same point in the distance. The result: it's as if you were continuously tensing a particular muscle for a long period of time. Following the '20-20-20 rule' can help give your eyes a break: look at an object 20 metres away for 20 seconds every 20 minutes to relax your eyes.

4. Remember: severe visual impairments can have very different symptoms, and it's not always easy to recognise them immediately or gauge them properly.

5. Make sure you also take care of your magnifying visual device. Only use suitable cleaning agents – rather than your sleeve or a tissue – to clean your magnifying visual device. And don't forget: proper lens care increases the longevity and performance of your magnifying visual devices, ensuring better vision.
