The enhanced tests we are now doing on everyone were chargeable even with the NHS contract. We used to offer an opt in or opt out of enhanced testing. However all of our enhanced tests limit close contact between the patient and optician therefore making it safer for everyone. Our top enhanced eye test is £90 to pay privately. Even if we were still an NHS practice, the NHS contribution to it would only be £21.31. On our eye care plan you can have as much care as you need for less than £60 per year and also get a discount on your glasses, which would be cheaper compared to having an NHS test and paying the upgrades.
