Contact lenses are not an easy solution for every person suffering with vision problems. Some eye conditions make wearing contacts a difficult proposition. However, it does not rule out wearing contact lenses altogether. It just means patients need to discuss options with their eye care provider and obtain specialized hard to fit contacts for their specific vision problems.
Livermore Optometry is well known for our doctors' abiltiy to fit specialty contact lenses including toric, multifocal, gas permeable and scleral lenses.
Reasons for Specialty 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
Astigmatism: Astigmatism develops when the front of the eye curves into a bulge or oval shape. It causes blurred vision and 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 stuck in your eye.
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.
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.
Specialty Contact Lenses
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 many patients who suffer from Keratoconus as it is effective in containing corneal bulging and relieving pressure on the tissue for a Keratoconus sufferer. GP lenses often times allow for superior vision over soft contact lenses for patients who suffer from astigmatism.
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 on the eye. They are typically custom made to correct for a specific power at a particular orientation. For that reason, this type of lens takes longer to fit and manufacture.
Bifocal and multifocal lenses can help remedy presbyopia as each lens has both a distance and a near prescription. Monovision lenses are another option for presbyopia. This type of modality can have one eye fitted for distance vision and the other for seeing close objects such as the computer.
