Contact lenses are not always an easy solution for every individual suffering with vision problems. Some eye conditions make wearing contacts a difficult proposition. However, this does not rule out wearing contact lenses altogether. It just means that patients will have to discuss the many options with their eye care provider and obtain specialized hard to fit contacts for their specific vision problems.
Reasons for Hard to Fit Contacts
Finding contact lenses that fit and wearing contact lenses, in general, can be made more challenging when these conditions affect your eyes:
- Dry eyes
- Giant Papillary Conjunctivitis (GPC)
- Irregular Cornea
Astigmatism: Astigmatism develops when the front of the eye curves into a bulge or oval shape. It causes blurred vision. This can be difficult to correct because regular contacts cannot account for the bulging.
Dry Eyes: When eyes become excessively dry, it leads to irritation, burning, redness and blurred vision. Contact lenses can exacerbate these conditions by making it feel like a foreign object is in the eye.
GPC: This form of conjunctivitis is caused by inflammation on the inner surface of the eyelid. Protein buildup on contact lenses can make this condition worse.
Keratoconus: This is an uncommon condition that causes major discomfort when wearing contacts. Keratoconus happens when the cornea becomes thinner and allows the eye to bulge forward. The bulge forms into a cone shape.
Presbyopia: Eyes tend to have a tougher time focusing on close objects as they age. This condition is known as presbyopia. It typically affects people aged 40 or older.
Solutions for Hard to Fit Contacts
Wearing contacts is not impossible if you suffer from one of the above conditions. You do need to meet with an eye care professional, however, and get prescribed contact lenses that are tailored to deal with your specific vision condition.
Gas permeable lenses are a good solution for patients who suffer from GPC or Keratoconus. A gas permeable lens will limit protein deposits from accumulating, which will reduce GPC symptoms. It is also effective in containing corneal bulging and relieving pressure on the tissue for a Keratoconus sufferer.
Toric lenses are useful for correcting astigmatism. Since the lens needs to align with the bulge it is correcting, toric lenses must not rotate in order to fit properly on the eye. They are typically custom made to correct a specific astigmatism. For that reason, this type of lens takes longer to make and costs more than a traditional contact lens.
Bifocal and multifocal lenses can help remedy presbyopia. Monovision lenses are another option for presbyopia. This type of lens fitting can have one lens fit for correcting distance vision while the other lens is fit to correct near vision.
Medicated eye drops can be an effective solution for dealing with dry eyes. They will lubricate the eyes enough to make wearing contact lenses more bearable, although a punctal occlusion also must be done to plug the ducts in some extreme cases. GPC symptoms can also be lessened by using medicated eye drops. They flush out protein deposits and reduce inflammation.
