Do I need to know my prescription when visiting?
If you're an existing patient, don't worry, as all prescription records are kept on file, so there is no need for you to have a copy of your latest prescription.
If you're a new patient, however, we will have to undertake an eye test to determine your prescription, unless you have an in-date, valid prescription from a qualified practitioner.
We receive many patients who are unsure about their eye health. If you feel like you need more information regarding your eye examination, glasses, contact lenses or prescription please don't hesitate to get in touch with our practice.
Our members of staff will be more than happy to discuss any issues you may have.
Have another query?
How often should I have my eyes examined?
If you are:
  • Aged 15 or below - once every year
  • Aged 16-69 years - once every 2 years
  • Aged 70 years and over - every year
  • Diabetic and glaucoma patients - every year
  • Aged 40 years and over with an immediate relative with glaucoma - every year
The above are general guidelines and more regular eye exams may be required in some cases. Your optician will always advise you of this. Please contact us if you are still unsure.
When should my child have their first eye exam?
Children can, in theory, be tested at any age, but our recommendation for a child's first eye examination is around 3-4 years old (i.e. pre-school). However, if you feel your child may be struggling with an eye problem, our advice is that it's better to be safe than sorry. We always strive to make our exams as fun as possible for the child's benefit. 
How long does an eye exam last?
The length of an eye examination varies depending on the patient being examined, but a typical test usually lasts  40 minutes for an adult. 
Do I receive NHS entitlements?
You may be entitled to a free eye examination for a number of reasons. Some of these include: if you are aged 60 or over, suffer from diabetes or glaucoma, you're aged 16 and under, or if you are aged 17 or 18 and in full-time education.
For more information on NHS entitlements please check their website here.
Will I be suitable for contact lenses?
Contact lenses can be a great choice for those who want to partake in sports and other activities and also for those want the practicality of seeing clearly without the need for glasses. Fortunately, contact lens technology has improved drastically over the past few years meaning we can fit them according to your requirements. 
Contact Us for more information.
Do I still need glasses if I wear contact lenses?
We always recommend our patients to keep a pair of up-to-date glasses in case you are temporarily unable to wear your contact lenses and also to help prevent over-wear of contact lenses.
I've lost my contact lenses - can you help?
Of course! We keep a range of contact lenses in stock, so if you've lost yours, give us a call or come into the practice and we'll hopefully be able to provide you with a replacement.
I'm very worried about an eye problem, can you see me urgently?
Unfortunately we are not an "emergency service" but we are very happy to see you if we have a full appointment slot free in our diary; these appointments are usually private rather than NHS appointments. Other options are for you to contact your GP or even the nearest A&E (Addenbrooke's in Cambridge) if you are very concerned about your vision or symptoms.
How do I book an appointment? 
We strive to make it as convenient as possible for you to arrange an appointment. If you want to book online follow through to our MySight portal here.
Alternatively, you can call or email the practice to book your eye exam, follow through to the Contact Us page to view contact information.
