Explore different types of contact lenses

Yes, your contact lens prescription is different from your eye glasses prescription because it includes base curve, diameter and material or brand, which are all specifications unique to contact lenses. These specifications ensure the lens is a good fit for your eye. They may vary based on the brand your eye doctor prescribes after assessing your eye health and lifestyle. Also, if you have astigmatism or presbyopia, your prescription may include measurements for those as well.

Silicone hydrogel is the newest generation of soft contact lens material. Silicone hydrogel contacts are breathable lenses that allow more oxygen to reach the cornea than hydrogel lenses, which may help reduce the risk of complications, such as corneal swelling. This material is typically combined with coatings or wetting agents to help with lubrication.

Contact lenses and glasses both have their benefits. For example, contacts offer an unobstructed view of the world and won't get in the way of wearing helmets or sunglasses. However, glasses require less care than reusable contacts and can add an extra element of style to an outfit. It’s up to the wearer and their optometrist to decide which is the best option for them.

When prescribed by a qualfied eye doctor and worn as directed, colored contact lenses can be as safe to wear as any other contact lens. Where problems usually arise is when people don't follow their eye doctor's instructions or wear colored contacts that are not prescribed for them. You should never wear colored contacts bought without a prescription from a costume store or online, or wear contacts prescribed for someone else. The only way to obtain safe colored contacts is to visit your eye doctor for a contact lens fitting.

Yes, most contact lens wearers can usually wear their contacts for 10+ hours per day, but you should always follow the wearing schedule recommended by your eye doctor. If you don't know, or you've forgotten your wearing schedule, be sure to ask at your next annual eye exam. Keep in mind, unless directed otherwise by your eye doctor, you shouldn't wear your lenses while you're sleeping because that can lead to eye infection or other serious eye health issues.
