About This Quiz

Eyesight is a funny thing. While most of us were lucky enough to be born with the ability to see, some were not. As we age, our eyesight, along with some other senses, also decline and it's just not as easy to get things done as it used to be. No matter what stage of your life you're at, it's essential to find out whether you've still got it (sight-wise) or whether you'll be in need of some assistance now or in the near future. 

So today, we want to test how great your eyesight is. We've hidden some animals, foods and even people in some backgrounds and it's your job to tell us whether they're there on not and who and what they are. Now while some of them may be easy to spot, others are ridiculously difficult. That's why not many people can get through this eye test. 

Do you think you'll make the cut? Or will you need to start eating a pack of carrots every day for the rest of your life? Go ahead and get started on this quiz to see if you can spot the items that we've sneakily hidden inside them!
