Both offer eye tests, so the choice is up to you. However, there are reasons to choose one over the other. Here are a few things to bear in mind.
If you have specific and acute complaints or pain such as a foreign object in the eye, itching, burning or redness, then you should head directly to an ophthalmologist or eye specialist. However, your eyes can also be in trouble without you picking up on any symptoms. So if you want to make sure that everything is okay with not just your vision but also the health of your eyes then an eye specialist is your best bet.
If you think your vision has changed but you have no other complaints, you can visit an optician. As a rule, it is possible to get an appointment quickly and without hassle. Depending on the test results you might be able to choose new glasses there and then, thus saving yourself a journey.
Important: Whatever else, make sure to notify the eye specialist or optician about any chronic illnesses or medication you are taking. These can have an effect on your vision and thus have to be taken into account. Obviously, an eye test cannot be carried out under the influence of alcohol or drugs.
