A contact lens or sometimes referred to as a corrective lens is a thin disk which floats on the surface of the eye, providing vision correction. With advances in optical technology, almost everyone now can wear contact lenses, regardless of the type or extent of their vision problems. This includes patients with astigmatism and those who need bifocal or multifocal lenses. Our practice offers a comprehensive array of contact lenses to suit our patients’ individual needs – from daily disposables or extended-wear soft contacts to rigid gas-permeable lenses. We can help you find out which contact lenses are best for you. There are two classifications of contact lenses – soft and rigid gas permeable lenses. All contact lenses require a prescription.
Soft Contact Lenses
Daily-wear Lenses Daily-wear soft contact lenses are by far the most popular type of contacts worn. Made of a flexible plastic polymer, daily-wear lenses are put in each morning and taken out each night. They are replaced according to an established schedule.
Extended-wear Lenses Extended-wear soft contact lenses can be worn all the time, including while you sleep. Depending on whether you have 7-day (standard) or 30-day lenses, you only need to take out and clean your contacts once a week to give the eyes a rest and reduce the risk of a corneal infection. Extended-wear lenses are made of soft silicone that retains moisture longer than daily-wear contacts, allows more oxygen to reach the eye, and prevents bacteria and protein buildup. Although many patients prefer the convenience of 30-day contacts, be aware that they tend to be stiffer than 7-day lenses, scratch more easily and may be blurrier.
Disposable-wear Lenses Disposable soft lenses are intended to be thrown out and replaced after you’ve worn them for a certain length of time. This makes them even easier to maintain than regular soft contacts. Many disposable lenses are designed for replacement each morning, every two weeks, or even every months. Daily-wear disposables are worn during waking hours only, while extended-wear disposables can be worn for longer periods.
Rigid, gas-permeable contacts offer several benefits over soft lenses.
- Can correct a wider range of vision problems, including a high degree of astigmatism
- Provide sharper vision than most soft lenses
- Allow more oxygen to pass through to the eye, reducing the risk of corneal irritation
- Are more durable than soft lenses and don’t need to be replaced as often, lasting as long as two or three years
- Less likely to tear like soft contact lenses
- Less prone to a buildup of deposit. Because they are much harder than flexible contacts, gas-permeable lenses may take some getting used to when you first start wearing them.
- They are also more likely than soft lenses to slip off the center of your eye and require adjustment, making them an inconvenient choice for patients who play sports or participate in other demanding activities. However, most patients soon grow accustomed to the feel of gas-permeable lenses and are satisfied with the improvement in vision they offer without the need for glasses.

Contact Lens FAQs
Exposing contact lenses to water may increase the risk of a severe eye infection that could lead to vision loss or blindness. If you do swim with your contacts, replace them immediately.
Even with contact lenses approved for continuous overnight use, sleeping in contacts increases the risk of eye infections. It is important to understand that an infected lesion on the cornea may result in extreme pain, and that permanent vision loss is greater for those who sleep in their contact lenses, than for those who do not wear them overnight.
Regardless of the number of days you wear your contact lenses, it should be replaced as recommended by an eye doctor. For example, if you are wearing monthly wear contacts, you should discard them after one month after removing it from the original package.
If you are only wearing contact lenses on occassion, you should discuss your options with your eye doctor. Daily wear contact lenses may be a safer and less expensive option.
No, this is impossible. The inner surface of your eyelids are continuous with the outer covering of the white part of the eye. So if a contact lens gets dislodged from the cornea, it may be difficult to locate the lens under your eyelid. However, the lens cannot get trapped behind, or within your eye.
At least once a year, because federal law states that a contact lens prescription expires after one year. More frequent visits may be recommended for some (e.g. patients who require a custom lens design)
Yes. Be sure to inspect your contact lens before insertion. When the contact lens is right side out, it will be bowl shaped with the edges facing upward. When the contact lens is inside out, the edges will face more out instead of up.
