Frequently Asked Questions

It is usually recommended that most adults should have an eye exam every 2 years. Children under 16 can be 1-2 years. An annual test is advisable for anyone who has diabetes or a direct relative with glaucoma (over 40). Your optician may also advise annual eye exams for various other reasons.
Standard Sunglass lenses help to protect our eyes from harmful UV rays, however they do not block out sudden glare you can experience from water or when driving. This glare can often be blinding and hazardous. Polarised lenses act as a filter that blocks unwanted visible light reflected from horizontal surfaces such as water and the road, allowing the wearer to obtain more comfortable vision and better clarity. Polarised lenses are great for Drivers, Skiers and Fishermen.

Varifocal lenses are essentially a spectacle lens that contains three different prescriptions. This type of lens consists of distance vision at the top, intermediate vision in middle and near vision at the bottom. Unlike old fashioned bifocals the lenses are blended and the different segments are seamless, so cosmetically they look just like a single vision lens! As our eyes begin to age, focussing on near tasks and the computer can become a struggle and you may be finding that you need your current glasses more often or your arms are simply just not long enough, the technical term for this is Presbyopia. Carrying several pairs of spectacles around with you can be quite annoying and one pair can often get misplaced. Varifocals are a convenient and effective way of eliminating these problems by incorporating all you need in one pair of glasses.
If you are new to Varifocals it is perfectly normal for them to take a little time to get used to. Common Problems
  •  Unsteady feeling when walking
  • Distorted or blurry vision when reading
  • Blurred vision when you look to the side
  • Lifting your head a lot to get clear vision on the computer and reading
Each Varifocal lens contains a clear corridor of vision down the centre of the lens. This is where you will get optimum vision. The prescription in the lens changes from distance at the top to reading in the bottom. Your vision will become more blurred as you look towards the periphery of the lens, this is due to power changes that occur at the edge of the lenses. The most up to date lens designs practically eliminate this. Initially you will need to adapt to the difference in your peripheral vision and will probably require some slight changes in horizontal head and eye movements. Sensitivity to this area of the lens will diminish with time as you become more accustomed to your new lenses. Hints and Tips for easy Adaptation
  • Do not interchange between your old and new spectacles
  • Wear your new glasses non-stop throughout the day
  • Wear your new glasses where they were fitted by your Dispensing Optician
  • Point your nose to what you want to look at, turn your head (instead of just your eyes)
  • Lift you chin up and keep your eyes down for reading
  • Be careful when going up and coming down stairs and curbs for the first few weeks
For most people the adaptation period will only last a few hours. Some individuals may need several days or even weeks before they feel completely comfortable. It is important remember that everybody is different and will have different visual experiences especially with Varifocals. The fitting of your varifocal spectacles plays a vital role in how you are getting on with them and is key to ensuring you are getting optimum vision. So if they aren't fitting quite right and they keep slipping down your nose then please do come in and have them adjusted by one of our Dispensing Opticians. If you've been wearing Varifocals for several weeks or longer and your vision feels uncomfortable in any way, please call in and speak to one of our fully qualified Dispensing Opticians.
Myopia/Short-Sighted: This is an eye condition where the objects in the distance appear blurry and objects close up appear clear. However this does vary with its severity. People may also squint or have eye strain. It usually occurs when the eye is either too long, the lens inside the eye is too powerful or the cornea is too powerful. This causes the light in the eye to focus in front of rather than on the retina and is corrected with minus lenses. Hyperopia/Long-Sighted: This is en eye condition where objects close up appear blurred and clear in the distance but again this varies with how severe the prescription is. Other common symptoms are headaches, trouble focussing or eye strain and squinting. This normally occurs when the eye is too small or the lens/cornea is too weak and light focuses behind the retina. It is corrected with plus lenses.
Astigmatism is when the cornea/lens is irregular in shape. Instead of being spherical (like a football) they tend to be curved or ''rugby ball'' shaped. Symptoms include blurry vision, eye strain and headaches. Most people will have some level of astigmatism and it is usually present in conjunction with being long-sighted or short-sighted.
Presbyopia is a normal ageing process where the lens inside the eye becomes harder and thicker. This causes difficulty with focusing up close/reading. Symptoms include difficulty with near tasks, holding objects further away to see them clearly, having headaches and eye strain. It usually starts age 40+ and can be corrected with prescription glasses.
Cataracts occur when the lens inside the eye becomes cloudy and opaque. This blocks the light falling on the retina and can make vision feel cloudy/misty or blurred. They also cause issues with glare and can make colours looked washed out or faded. Cataracts are mostly age related, however, they can also be caused by diabetes, trauma, some medications and UV light. To slow the progression of cataracts you should wear sunglasses when outdoors.
Glaucoma occurs when the optic nerve becomes damaged which causes a loss of vision. The damage is normally caused by a build up in pressure in the eye. Occasionally sudden/acute glaucoma can occur. This usually causes severe eye pain, red eye, headaches, blurred vision and haloes around lights. This needs urgent medical attention. Glaucoma can normally be easily treated with eye drops if caught in time. Unfortunately loss of vision normally occurs late in the disease and is irreversible at this point. Regular eye checks are very important to pick up glaucoma in time. There is no known cause of glaucoma. Risk factors include age, race and a family history of the disease.
AMD occurs when the macula which the 'fine point' on the retina becomes damaged. There are 2 forms of AMD: wet and dry. It usually affects the central vision and can cause difficulty reading, distorted vision and colours to appear washed out. Dry AMD: this happens when there are a build up of deposits on the macula called drussen. It is the most common form of AMD and is the less severe of the two. There is no know treatment at present, however there are some lifestyle changes which can help the progression of the disease. Wet AMD: this happens when abnormal blood vessels grow under the macula causing a build up of fluid. Wet AMD is usually treated with injections or laser treatment and it is vital that is is treated ASAP (usually within a few days) to prevent vision worsening. Symptoms include distorted vision, blind spots or a sudden drop in vision. If any of the above happen, attend your optometrist immediately. Risk Factors: age, smoking, UV light, diet. Lifestyle changes: to help prevent/slow down the progression of AMD ◦ stop smoking ◦ keep you eyes protected from UV e.g. sunglasses ◦ have a good varied diet with plenty of fruit and veg. There are also vitamins (lutein) which have been proven to help and should be taken in conjunction with a good diet cut down on alcohol and keep a healthy weight
Often the above symptoms are caused by 'dry eye'. Dry eye occurs when the eye doesn't produce enough tears or the tears that are produced are of poor quality. This causes the eyes to become irritated and can cause redness, itchiness, burning, grittiness, watering etc. If you think you have dry eye why not book in to our Dry Eye Clinic?
Daily disposable lenses are worn for 1 day only and then discarded. You should never wear a daily disposable lens for more then one day. Reusable lenses are worn every day and replaced as advised by your contact lens optician. We usually recommend you change your lenses every 2 weeks or monthly depending on the brand we prescribe. You will need to clean and disinfect your reusable lenses every day.
A contact lens prescription requires various measurements to be included, such as the curvature and size of contact lens needed to fit your eye. The power required is usually different to your glasses prescription too, as your lens fits directly on your eye.
Yes you can! Research and development is constantly ongoing in the contact lens world meaning more and more people than ever are now able to wear contact lenses. It is now possible to have contact lenses in daily disposable and reusables to correct your astigmatism. They are usually known as 'toric' contact lenses.
Absolutely! In fact you may find wearing lenses whilst partaking in your favourite sport is more convenient for you. Glasses can slip down your nose or break on impact, whereas your contact lenses should stay put. Your contact lens optician can advise you on the best type of lenses for your needs.
No. This is a very common myth! Contact lenses may occasionally get stuck under your eyelid, but that is easily dealt with. Your lens cannot get lost as the back of your eye! Your eyelids connect with your eye to form a barrier meaning that it is impossible for a lens to get through.
No, you must not wear your lenses whilst swimming, using a sauna or jacuzzi or even bathing. Water borne bacteria and other bugs such as acanthamoeba can attach to contact lenses and cause infection. This is particularly a problem in public pools where there can be traces of urine and and all things unpleasant. Why not buy some prescription goggles if you are serious about swimming? Goggles over your contact lenses is not ideal as water can seep in.
