Contact lenses are contact lenses, right? There’s not a big difference between them except the strength of the prescription. Isn’t that true? There are many different types of contact lenses, materials, and styles. Once upon a time, contact lenses were made of glass and very thick and uncomfortable to wear. However, contact lenses have dramatically improved over time in material, thickness, and styles.
Contact lenses use two main materials: plastic (hard) and silicone hydrogels (soft). Plastic (hard) lenses correct a variety of vision problems, more than soft lenses, are smaller, and last a long time. Silicone hydrogel (soft) lenses are more common for most people because they correct most common vision problems, are more comfortable, and stay in place easily. Your eye care needs will determine your prescription. Whether you have astigmatism, your prescription strength, and how long you keep your lenses determines as well.
Short vs. Long Term Wear
Most contact lens wearers use silicone hydrogels and they last about two weeks to a month. Your physician recommends the timing. Bacteria and damage will build up the longer you wear them. This is especially true when contact lenses and cases are not cared for properly. Some users opt for “dailies.” Dailies are replaced, well, daily, and ensure that your contacts are always clean, ready to use and give you clear and bright vision. On the other end of the spectrum, plastic, gas permeable lenses can be kept for a much longer period. Your ophthalmologist will discuss with you what the best option for your situation is. If you wear contacts for long periods, it’s very important to visit your ophthalmologist frequently to make sure that your contacts are holding up and that you have no infections beginning.
One contact is slightly tinted blue in most silicone hydrogels so that you always know which eye it’s supposed to go in. However, they don’t change the color of your eye. Some people use prescription lenses to alter the color of their eyes. They work with their doctor to find the right option that is safe and suitable. Never buy colored contacts online or from corner stores. These are not safe to put in your eyes and could cause infection or worse.
