Also known simply as contacts, contact lenses are thin lenses that are positioned directly on the surface of your eye. As a medical device, they are often used to correct vision impairment, treat certain eye conditions, or temporarily change the appearance of the eye. If an eye exam indicates that corrective lenses are needed, then you may be offered contact lenses along with eye glasses.
Your Contact Lens Questions Answered
What Are the Benefits of Wearing Contact Lenses?
Contact lenses can improve your vision by compensating for near-sightedness, far-sightedness, or both, as determined by Dr. Weinberg. In addition, contact lens wearers enjoy several benefits that are not available to those who wear eyeglasses, such as:
- Increased peripheral vision
- Reduced vision impairment due to rain, snow, sweat, or condensation
- Ability to wear non-prescription sunglasses, goggles, or protective eyewear
In some cases, special contact lenses may be recommended to alleviate symptoms caused by medical conditions such as color deficiency (color blindness), night vision, or dyslexia.
Could a Contact Lens Get Lost behind My Eye?
No. If you rub your eye while wearing contact lenses, a lens could become dislodged and move under your upper eyelid, but it cannot move behind your eye.
Can I Sleep While Wearing Contacts?
We do not recommend doing so unless you have prescribed lenses that are designed for long-term use, including use during sleep.
How Often Should I Remove My Contact Lenses?
This depends on the type of lens you use. Daily wear contact lenses should be taken out and cleaned each night before you sleep. Extended wear contacts are designed for continuous wear, even during the night, for several consecutive nights before removal.
Can Children Wear Contact Lenses?
This depends on how responsible your child is. You, your eye doctor, and your child should make this decision together.
Is a Contact Lens Prescription Different from an Eyeglasses Prescription?
Yes, because a contact lens rests much closer to your eye than eyeglasses; this affects how well the lens works with your eye to create a clear image.
Can I Change My Eye Color with Contacts?
Yes, even if you don't need visual correction. Contact lenses are available with sheer tints and opaque tints. If you have a light eye color, then either type will work for you. If your eyes are dark, then you'll see more dramatic effects with the opaque lenses because they cover your natural eye color.
