Cataracts are characterised by blurry spots that develop in the lens of the eye that prevent parts of the light from reaching the back of the eye, therefore causing unclear or foggy vision.

Unfortunately, the condition, although not associated with pain, is the main cause of impaired vision worldwide.

Cataracts mainly affect people older than 50 years old. Indeed, you can still drive your car if you have cataracts, provided your vision meets the legal requirements for driving.

If you want to reduce the risk of developing cataracts, we recommend that you take care of your eyes by, for instance, wearing sunglasses with UV protection (especially here in Spain!)


If you have cataracts, you will most likely experience unclear, blurred, or foggy eyesight, or you may see a few blemishes on the eyes, which will make the vision less clear.

Cataracts are, however, not painful and do not cause red or irritated eyes.

Furthermore, cataracts develop over many years and occur mostly in both eyes. However, the condition may affect each eye differently.

Other symptoms include:

  • Double vision

  • Impaired vision in dim or very bright lighting

  • Clear light sources dazzle or are unpleasant to look at

  • Colors seem faded with a yellow or brownish tinge

  • Circles of light are seen around sharp light sources, for example, car headlights

Here at Heiko by Heiko, we provide our customers with a free extended eye test, which includes tests for cataracts and glaucoma.

We highly recommed getting your eyes tested annually in order to identify cataracts, among other things because, if left untreated, the condition can lead to visual impairment.
