The Different Types Of Contact Lenses
If you are in the market for contact lenses, you have several choices available. Contact lenses come in several materials and styles for comfort and to fit your lifestyle. Knowing the common lens types can be helpful when you go in for your eye exam. Keep reading to learn more about different types of contact lenses and their benefits.
Standard Soft Lenses
Most people use standard soft lenses for their vision correction. These lenses are made of plastic or silicone hydrogels that allow maximum oxygen penetration. Most people find soft lenses comfortable and the vision correction they offer to be good. They are ideal for new contact lens wearers. You can get soft lenses for just about any prescription.
Hard (Gas Permeable) and Hybrid Lenses
Hard lenses offer many benefits, such as great vision and durability. Optometrists usually reserve them for people with severe astigmatism or who need a higher power lens. They are usually specially designed to fit your cornea's shape. Some people find them uncomfortable. However, you can sometimes find hybrid lenses with a hard center and a soft edge. Hard lenses require a more complicated cleaning regimen than soft lenses.
Toric or Multi-focal Lenses
Toric and multifocal lenses are soft lenses designed to correct mild vision irregularities. For example, those with mild or moderate astigmatism may do well with these lens types. Multi-focal lenses are similar to progressive lenses in glasses. They allow you to see both close up and at a distance, similar to bifocals.
Specific Duration Lenses
For soft lenses, you may have an additional choice in how long you can wear them before replacing them. In the past, you usually kept the same lens for up to a year. Over time, proteins and other buildup made these lenses uncomfortable and more difficult to see through. Modern lenses are usually disposable, and you can often choose the duration you want.
Daily disposable lenses are excellent for your eye health and comfort. They also offer easy care as you throw them away when you're done. You don't need to clean or store them. However, they can be pricey, so many choose weekly or monthly lenses. You must do daily cleaning and storage with those, but you still get a fresh lens before the old one has too much buildup.
You may need a more specialized lens if you have an unusual eye condition like a damaged cornea. While most people can wear contact lenses, some people cannot or should not do so. Your optometrist will let you know if you are unsuitable for contact lenses. Contact an eye doctor for an exam to see if you are a good candidate.
