The eye is a complex organ that works rather like a camera. Complaints affecting any part of the eye can affect vision and many eye problems that cannot be corrected with glasses or contact lenses (such as glaucoma, retinal, corneal or macular problems) can be treated with good results if early advice, by an ophthalmologist is taken.
To see well at all distances without glasses can be a problem, even in otherwise healthy eyes and this is usually due to myopia (short sight), hyperopia (long sight), astigmatism or simply due to age (presbyopia).
If wearing glasses can correct vision, then, in many cases the correction can be made permanent.
An initial consultation and examination will confirm whether you are suitable for long-term correction and which option might best suit your particular life style.
