Emmetropia is the ideal condition in which objects are focused sharply on the retina where one does not require any spectacle or contact lens correction.​

Photophobia is an intolerance or fear of light.​

Amblyopia is a reduced vision, generally in only one eye. The condition usually results from poor eye co-ordination, from having a turned eye, or after having one eye which requires a far greater lens power than the other eye.​

​Glaucoma is a disease where the pressure within the eye is typically increased (although not always). This can damage parts of the eye, and if left untreated may result in blindness.

​Cataract is an opacity or clouding of the lens inside the eye, thereby distorting the light as it enters the eye. Cataract is often confused with pterygium but cataract cannot be seen on the surface of the eye.

​Pterygium is a triangular growth of degenerative tissue on the white of the eye (sclera), usually on the nasal side, that may extend onto the clear window of the eye called the cornea.

Spots and floaters are semi-transparent specks of natural materials inside the eye, which sometimes can be seen floating in the field of vision that are caused by debris left over from before birth, injury or eye disease. A full eye examination will determine the cause and whether any follow-up is needed

A routine part of our eye examinations is an assessment of colour vision, especially for children. Colour blindness is almost always inherited, although it can be acquired condition as a result of some diseases or injuries.

​Aberration is the phenomenon that occurs when light traveling through the media i.e. the cornea or the lens of the eye , and it does not form a perfect image.​

Is it difficult to wear contact lenses?

Not at all. You will be pleasantly surprised to discover how comfortable it is to wear contact lenses. Initially, your eyes may react to the new sensation, but within minutes most people tend to get used to wearing contact lenses, that they even forget they are wearing them.

Why do people choose contact lenses instead of spectacles?

Because contact lens sit directly on your eye they move with your eyes as you change your view so you have a natural field of view, without a frame getting in your way.

  • * The lens is directly on your eye so does not magnify or minify your eyes or your view as spectacle lenses would.
  • * They do not steam up like spectacle lenses. You have more freedom to play sports if you don’t wear spectacles.
  • * Some people prefer their appearance without glasses on. Contact lenses tend to give better vision than spectacle lenses as they are directly on the surface of your eye.
  • * Contact lenses may give better vision than spectacles for some visual conditions such as severe short – sightedness, long – sightedness or corneal distortion, or after cataract removal.

Am I too old to wear contact lenses?

No! Wearing contact lenses depends on the health of your eyes and your prescription. Your eyes may be slightly drier if you are older, but this doesn’t mean you can’t wear contact lenses at all. Your Contact Lens Optician will decide on the contact lens most compatible for you.

What are the different types of contact lenses available?

There are various kinds of contact lenses available for different purposes. They are :

  • * Rigid Hard Lenses and Rigid gas Permeable Lenses (semi – soft lenses).
  • * Soft daily wear and Disposable Contact Lenses.
  • * Tinted & Coloured Contact Lenses.
  • * Toric soft contact lenses for astigmatism.

Are soft or gas permeable contact lenses best?

This really depends on how you look at it! Several factors are involved – prescription, comfort, cost, eye health, lifestyle. Soft contact lenses let less oxygen through to the eye than gas permeable contact lenses, so aren’t quite as healthy. This would make you think that everyone would wear rigid gas permeable contact lenses, wouldn’t it? Well, it’s the opposite – about 85% of contact lens wearers have soft contact lenses. The reasons for this are that rigid gas permeable lenses are more difficult to get used to as, initially, they are less comfortable. Gas permeable contact lenses are also not used for sport as they can be dislodged from the centre of the cornea. They should also be worn daily so the cornea can learn to tolerate the lens. This would now make you think, why does anyone wear gas permeable contact lenses! Well, they are much healthier for the eye, they are smaller, give excellent vision, the solutions to clean them are simpler and cheaper, they last longer and can correct astigmatism automatically. So, there is no “best” contact lens – it really depends on several individual factors which your Contact Lens Optician will discuss with you.

Can I swim with my contact’s on?

Your Optometrist will discuss this with you. Firstly, the contact lens could be washed out of your eye. Secondly, a swimming pool is full of bacteria and chemicals that will be absorbed by the contact lens. These will then remain in contact with your eyes until you remove the contact lenses, which can cause discomfort and possibly infection. It is much better to wear prescription swimming goggles.

Can my child wear contact lenses?

Very young children are usually only offered contact lenses in special circumstances. This is because they need a high level of care and maintenance to limit the risk of eye infection. They will also need frequent check-ups by a Contact Lens Optician to check that the health of their eye is not being affected. Older children, once they are responsible enough, should be able to wear contact lenses. Often, they are offered daily disposable lenses to wear occasionally for sport. This ensures that the child is always wearing a clean sterile lens, as they may not understand the importance of good lens hygiene.
