Park Ophthalmology Clarifies the Differences in Contact Lenses

Park 05-11-15 ID100111139 marin fdpSelecting eyeglasses is simple. Pick out a frame that looks good and the doctor will make sure the lenses provide vision correction. But as ophthalmology and technology continue to make advances, patients of ophthalmologist Dr. Beth R. Friedland find they have more and more choices. Park Ophthalmology offers Triangle area patients the latest innovations and the helpful staff is always available to answer questions about new products.

Park Ophthalmology shares five aspects of vision correction from the U.S. Food and Drug Administration about contact lenses:

  • Prescriptions required: Contact lenses are classified as medical devices. As such, they cannot be dispensed without a valid prescription. Clients need to have their vision checked annually to make sure they have the correct prescription.
  • Soft lenses: Soft contact lenses are flexible plastic and allow oxygen to pass through to the cornea. They may be easier to adjust to and more comfortable than rigid lenses.
  • Rigid lenses: Sometimes called “hard” contact lenses, rigid gas permeable contact lenses may provide clearer vision than soft contacts and they last longer. Although they are easier to handle, some patients find them less comfortable to wear than soft lenses.
  • Extended wear: Some soft lenses and a few rigid gas permeable lenses can be worn for up to 30 days, including overnight. Dr. Friedland will consult with clients to determine whether continuous wear lenses are an option and the length of extended wear that is appropriate.
  • Disposable lenses: According to the FDA, most people who use soft lenses choose disposable contacts. While some people replace lenses daily, a common practice is to take them out before bed, place them in a disinfecting solution overnight and use them again the next day. Dr. Friedland will advise clients of the best cleaning solution to use for specific lenses.

Contact lenses continue to grow in popularity and ease of use. Unlike glasses, contacts provide a full field of vision, a benefit to those who enjoy playing sports. Making a choice doesn’t have to be overwhelming. Park Ophthalmology welcomes all questions about the latest developments in contact lenses.
