Are you thinking about starting to wear contact lenses or switching to a different type of contact?
Wearing contacts can make a big difference in the way you see things – such as sharper details and brighter colors. And technology has made contacts more comfortable than ever.
While we look forward to discussing contact lenses and working closely with you to find the right type of lens to meet your needs, here are some things for you to think about:
Reasons to consider contact lenses
- Contact lenses move with your eye, allow a natural field of view, have no frames to obstruct your vision and greatly reduce distortions.
- Unlike glasses, they do not fog up or get water spots.
- Contact lenses are excellent for sports and other physical activities.
- Many people feel they look better in contact lenses.
- Compared to eyeglasses, contacts may offer better, more natural sight.
Some things to remember about contact lenses
- Compared to glasses, contact lenses require a longer initial examination and more follow-up visits to maintain eye health. Lens care also requires more time.
- If you are going to wear your lenses successfully, you will have to clean and store them properly, adhere to lens-wearing schedules and make appointments for follow-up care.
- If you are wearing disposable or planned replacement lenses, you will have to carefully follow the schedule for disposing the used lenses and using new ones.
Contact lens types
There are two general types of contact lenses: hard and soft.
Rigid gas-permeable (RGP):
The hard lenses most commonly used today are rigid gas-permeable lenses (RGP). They are made of materials that are designed for their optical and comfort qualities. Hard lenses hold their shape, yet allow the free flow of oxygen through the lenses to the cornea of your eye.
RGPs provide excellent vision, have a short initial adaptation period, and are easy to care for. RGPs are comfortable to wear, have a relatively long life, and correct most vision problems.
The disadvantages are that RGPs require consistent wear to maintain how comfortable they feel, and can occasionally slip off-center of the eye.
Soft contact lenses:
Soft lenses are the choice of most contact wearers. These lenses are comfortable and come in many versions, depending on how you want to wear them.
Disposable-wear lenses are removed nightly and replaced on a daily, weekly, biweekly, or monthly basis and are easy to get used to wearing.
Daily-wear contacts do not need to be cleaned and are great for active lifestyles but don't correct all vision problems and vision may not be as sharp as with RGP lenses.
Extended-wear soft contacts can usually be worn up to seven days without removal. Be sure to ask us about extended-wear contacts and a possible greater risk of eye infections.
Colored soft contacts change your eye color, the appearance of your eye, or both. They are available by prescription and should only be worn after an eye exam and fitting by an eye-care professional. Over-the-counter colored contacts are illegal in some states and pose a serious danger to your eye health.
Bifocal or multifocal
Bifocal or multifocal contact lenses are available in both soft and RPG varieties. They can correct nearsightedness, farsightedness and astigmatism in combination with presbyopia. Visual quality is often not as good as with single vision lenses; however, for some people the ability to correct presbyopia is worth it.
Contacts are a great fit for many patients but don't forget to be prepared
Carry a backup pair of glasses with a current prescription—just in case you have to take out your contacts. Contacts can make your eyes more light-sensitive, so don't forget to wear sunglasses with UV protection and a wide-brim hat when you’re in the sun.
Hygiene is the most critical aspect to successfully wearing contacts
When cared for properly, contact lenses can provide a comfortable and convenient way to work, play, and live the millions of people who wear them. While contact lenses are usually a safe and effective form of vision correction, they are not entirely risk-free.
Contact lenses are medical devices, and failure to wear, clean, and store them as directed can increase the risk of eye infections. Not following your eye doctor’s directions raises the risk of developing serious infections. Your habits, supplies, and eye doctor are all essential to keeping your eyes healthy.

Mark your Calendars!!! On Monday, Aug. 21, 2017, a solar eclipse will be visible across the entire continental United States.
A solar eclipse occurs when the moon blocks any part of the sun, and with this one, all of North America will experience at least a partial eclipse lasting 2 to 3 hours.
A lucky few million people along a 70-mile-wide path from Oregon to South Carolina will experience a brief total eclipse when the moon completely blocks the sun for up to 2 minutes. For that 2 minutes or so it will look like nighttime along that path.
This total eclipse will make the solar corona visible, and stars and the planets may also be visible during this time.
But looking directly at the sun before it is covered is unsafe. Although there is a limited chance of eye damage if you are in the proper area during the total eclipse it is not worth the risk of retinal damage to even take a quick look at the eclipse if it is not “total”.
A large part of the country is not along the pathway where the eclipse will be total so you should not look at the sun without protection.
The only safe way to look directly at the eclipse is through special solar filters, such as “eclipse glasses” or hand-held solar viewers.
Ordinary sunglasses, even if they are very dark and polarized, are not safe for looking at the sun. To date, four manufacturers have certified that their eclipse glasses and handheld solar viewers meet the ISO 12312-2 international standard for such products: Rainbow Symphony, American Paper Optics, Thousand Oaks Optical, and TSE 17.
All the companies above have instructions printed on or packaged with their filters. You MUST follow the instructions to keep your eyes safe. Always supervise children using solar filters.
Specific instructions are found below, courtesy of NASA’s eclipse website https://eclipse2017.nasa.gov/safety:
1. Stand still and cover your eyes with your eclipse glasses or solar viewer before looking up at the bright sun. After glancing at the sun, turn away and remove your filter - do not remove it while looking at the sun.
2. Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical devices. Similarly, do not look at the sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses or hand-held solar viewer - the concentrated solar rays will damage the filter and enter your eye(s), causing serious injury. Seek expert advice from an astronomer before using a solar filter with a camera, a telescope, binoculars, or any other optical device.
3. A solar eclipse is one of nature’s grandest spectacles. By following these simple rules, you can safely enjoy the view and be rewarded with memories to last a lifetime. An eclipse is a rare and striking phenomenon you won't want to miss, but you must carefully follow safety procedures. Don't let the warnings scare you away from witnessing this singular spectacle! You can experience the eclipse safely, but it is vital that you protect your eyes at all times with the proper solar filters. No matter what recommended technique you use, do not stare continuously at the sun. Take breaks and give your eyes a rest! Do not use sunglasses: they don't offer your eyes sufficient protection.

The solar eclipse is a spectacular sight but please remember to watch it safely.
