9 Contact Lens
Tuesday, July 28th, 2009 |
You may have thought about switching from your eyeglasses to contacts in the past, but were unable to for some reason. There have been many developments in contact lenses in the past several years. You might be pleasantly surprised if you ask your optometrist about switching to contacts.
You may be sure that you will never be able to insert and remove contact lenses. You may be convinced that you cannot keep a contact lens in your eyes. You may have been told in the past that you could not wear contacts because of astigmatism, you needed bifocal or multifocal lenses, or you had presbyopia. Developments in the manufacture of contact lenses have enabled people with all these worries and conditions to be fit with contacts. Not all types of lenses are suitable for every condition, your vision may not have the quality you want, and it is possible that your problem is too severe to be corrected with contacts, but there may now be a contact lens for you.
With the development of soft lenses, it is easy to quickly get comfortable with wearing contacts. You are actually less likely to loose a soft contact than a RPG lens.
For those with astigmatism, a toric lens has been developed. You may require a toric lens in one eye and spherical contact lens in the other. Your ophthalmologist will help you determine the prescription and contact lens material best for you.
For presbyopia (the loss of ability to focus close up associated with aging) bifocal or multifocal lenses or a monovision arrangement may be used. The bifocal contact lens works like bifocal glasses with far focus on top and near focus on the bottom. A multifocal contact lens has several points of focus for a smoother transition from near to far. A monovision arrangement is when a lens for distance vision is used in one eye (usually the stronger eye) and a lens for reading is used in the other. The brain usually becomes used to sorting out the focuses in a few days.
Here are some conditions when contact lens wear may be impossible or difficult:
If your eyes are severely affected by allergies
You work in an area with lots of chemicals and/or chemical fumes, or in an area with lots of dust or small particles of material floating in the air
You should not wear contacts while swimming
You have uncontrolled diabetes, severe arthritis in your hands, or an overactive thyroid
Your eyes are overly dry
Nearsightedness often cannot be corrected with contacts
There is not a specific age for children to wear contact lenses, but they should have the dexterity to insert and remove the contact lenses and old enough to assume the responsibility of handling the lenses.
With the developments in contact lens manufacture over the past few years, more and more people are now able to wear contacts. If you were told in the past that you could not wear contacts, you might want to ask your eye care doctor about the possibility of wearing contacts.
