A common refractive problem called astigmatism results in distorted or blurry vision because the cornea or lens has an uneven shape. There are a lot of possibilities now that contact lens technology has advanced. This tutorial will teach you how to select the astigmatism contact lens that best suits your needs by explaining the various types available.
Understanding Astigmatism and Contact Lenses
When the cornea or lens is not exactly spherical, astigmatism results. Vision becomes distorted or hazy as a result of the irregular form, which allows light to focus on several spots instead of just one. Toric lenses—a type of contact lens used to treat astigmatism—are made to address this problem by having distinct powers in each of the lens’s meridians. Choosing the appropriate contact lenses from the best contact lens clinic Chennai is essential for astigmatics to achieve comfortable and clear vision.
Types of Contact Lenses for Astigmatism
For astigmatism, a variety of contact lens options are available, each with unique advantages and considerations. Among the primary kinds are:
1. Contact lenses with soft toric
A flexible plastic substance used to make soft toric lenses permits oxygen to reach the cornea. Because they are comfortable and simple to adjust, these lenses are well-liked. There are several varieties available, including as daily, bi-weekly, and monthly disposables.
Pros: Suitable for the majority of prescriptions, comfortable, and generally accessible.
Cons: May rotate on the eye, which could lead to variations in vision.
2. Gas Permeable Rigid Lenses (RGP)
Compared to soft lenses, RGP lenses are composed of a more rigid substance, which improves durability and vision correction. Many people with astigmatism benefit from having sharper vision thanks to them.
Pros: Superior clarity of eyesight, long-lasting, and less prone to retain deposits.
Cons: It takes longer to adapt and may be less
3. Cross-Lens Contacts
Hybrid lenses provide a soft outer ring for comfort and a stiff center for sharp vision. They provide the advantages of soft lenses and RGP together, making them a good choice for anyone who need comfort and good vision.
Pros: Comfortable wear and clear vision.
Cons: More costly and possibly requiring more handling and attention.
4. Extended Wear Lenses
For a maximum of 30 days, extended wear lenses can be worn constantly, including overnight. Both soft toric and RGP versions are offered. For people who have hectic lives or find it difficult to wear contacts on a regular basis, these lenses are great.
Pros: The ease of not having to take out your lenses every day.
Cons: If not properly maintained, there is a higher chance of eye infections and problems.
Tips for Successful Contact Lens Wear
Adhere to the recommended wearing schedule: Maintaining the health and comfort of your eyes depends on you following the prescribed wearing and replacement schedule.
Maintain good hygiene: To prevent infections, wash your hands before handling lenses and make sure you follow the cleaning and storing guidelines.
Keep up with routine check-ups: Frequent ocular examinations from Sankara Eye Hospital guarantee that your prescription stays accurate and your lenses fit properly.
Speak with your eye care specialist: Talk to your eye care professional about any pain, changes in your vision, or problems so that your lenses or treatment can be adjusted.
Factors to Consider When Choosing Contact Lenses
Selecting the appropriate contact lenses for astigmatism requires taking into account a number of factors:
1. Prescription Drugs and Eye Health
Your eye doctor will assess your eyes to make sure they are healthy enough to wear contact lenses and will determine the proper prescription. A thorough examination of the eyes will determine the level of astigmatism and other refractive problems.
2. Convenience and Lifestyle
When choosing contact lenses, take your lifestyle and everyday activities into account. Daily disposables or extended wear lenses can be the convenience you require if you lead an active lifestyle. Daily disposables are an excellent choice if you would rather have less upkeep for your lenses.
3. Comfort
For contact lens usage to be successful, comfort is crucial. Particularly for people who are new to wearing contact lenses, soft lenses typically offer greater comfort than RGP lenses. RGP lenses, however, might become more comfortable for certain people after the initial period of adaption.
4. Cost
The price of contact lenses might differ greatly depending on the type and brand. When compared to monthly disposables, daily disposables are typically more costly over time, but they also remove the need for cleaning agents and lower the risk of infection. Although RGP lenses are more expensive initially, they may save money over time because of their longer lifespan.
5. Vision Quality
Clarity of vision is an important component. While most people can get by with soft toric lenses, RGP or hybrid lenses, which provide better vision correction, may be more advantageous for those with higher astigmatism levels or uneven corneas.
Conclusion
Understanding the various lens types, taking into account your lifestyle, comfort level, budget, and visual requirements, as well as maintaining correct lens care, are all important factors to consider when selecting the best contact lenses for astigmatism. You can improve your entire quality of life by collaborating with your eye care specialist to select the best contact lenses that provide comfortable and clear vision.
