Recent advancements in contact lens technology and manufacturing have made contact lens comfort and vision easier than ever. Depending on your prescription, eye health, and how often you want to wear contacts, there is likely a contact lens for you. Soft daily disposable contacts are gaining popularity because they are convenient and healthy for your eyes. These lenses are very thin, and therefore easy to adapt to. From an eye health perspective, these are the best lenses for you because there is no build-up on the lenses, which can lead to decreased wearing time and possible infections. In addition, these are very convenient because you don’t have to worry about cleaning and storing your lenses, or having to buy solution. The other advantage is you can wear these lenses as much or as little as you like. If you want to wear them just for sports, recreation, vacation, or just going out to dinner, these lenses are the choice for you. However, even if you want to wear them every day, dailies are still the most convenient and healthy lenses on the market.

If you need heavy contact lens wear including extended wear (sleeping in your lenses), you might want to try silicone hydrogel lenses. Some of these lenses are now FDA approved for up to 30 days of continuous wear. This new material makes the lenses firmer, and allows for an average of a 4 to 6 fold increase in oxygen flow to the eye. Obviously, there are some potential health issues with the eyes that come along with sleeping in your lenses, so it is not for everybody; that can be determined at your exam and at follow-up visits. Most people enjoy the freedom these lenses give you and the increased end of day comfort. If your eye receives more oxygen, it will be less fatigued and red at the end of the day.

Toric contact lenses are now better than ever. If you have astigmatism, that means the front part of your eye (the cornea) is more oblong-shaped, similar to an egg. Because the eye is not equally curved, a toric lens is needed to help you see well. These lenses are still soft and you care for them the same as any other lens. Toric contacts are now available in daily disposable and in the silicone hydrogel material.

For those of you who love your contacts but need some reading help, multi-focal contacts and monovision are your options. Multifocal lenses allow you to see both distance and near out of each eye, while maintaining binocular vision. Being able to see the same out of each eye enables the brain to use your eyes as a team, as compared to monovision, which corrects one eye for distance and the other for near. With monovision, you wear a single vision distance contact on one eye and a near lens on the other eye. Both modes of correction are popular and both have their attributes and drawbacks. Whether multi-focals or monovision would work best for you would depend on prescription and what your visual demands are at work and for leisure.

Lastly, color contacts are available in daily disposable, toric, and regular 2 or 4-week disposable lenses. The colors vary across the spectrum and will give you either a subtle change in color or a profound one. Some patients use these lenses full-time, and some wear clear contacts, but have a small supply of color lenses for special occasions. The nice thing is you can try on some of the colors in the office to see if they are a good fit for the change you are looking for.
Finally, it is important to remember that contact lenses are medical devices, and can cause eye health consequences if not worn and cared for properly. That is why annual exams are mandatory to ensure good vision and eye health. We will patiently work with you to determine which prescription and type of lenses would be best for you. Our goal is that your vision and comfort with your lenses is the best that it can be.
