Toric lenses are soft contact lenses designed to help with astigmatism. They are light to help stay in the right position on the eye, provide crisp and clear vision. Because of the complex nature of this eye problem, not many companies are designing toric lenses. In fact, a majority of the companies have discontinued the production of the devices owing to this challenge.
Types of Tints to Expect
Typically, contact lenses come in different tints, but there are three standard options you can find out there.
Enhancement tint: They are designed to improve the overall look of the natural eye by enhancing the color.
Opaque tint: they are designed to give you a completely new eye look by changing the color of the eyes from blue to green or red.
Unlike other types of contacts, toric lenses have limited choice when it comes to color or tint, especially if you are suffering from near or shortsightedness.
A majority of the colored contact lens are designed from conventional materials, experts say. These materials are less permeable to oxygen even though they can offer you the best vision and healthy eyes. It is recommended that you work with your eye specialist or optometrist to fit your lenses in a fashion that allow your cornea to be exposed to as much oxygen as possible.
Below are some of the things that you must consider when buying contact lenses to help with treatment of astigmatism:
Sliding of the colored section of the lenses over the pupil can create that unnatural appearance, especially if you are wearing opaque types. Therefore, ensure you buy contacts that do not slide over your pupil to avoid such scenarios.
Usually, the pupil changes in size to accommodate the varying light intensity. This might affect your vision when you have your contacts on.
While lenses are designed to help with improving the vision ability of your eyes, they can also impact your vision negatively. They are definitely a good alternative to conventional glasses, but they have potential risks that could impact your eyes. Therefore, you need to ensure you get the right contacts to avoid some of the dangers that come with fitting wrong contact lenses.
Some of the Potential Risks of Wearing Colored Contact Lenses
Some of the risks include corneal infections, ulcerations, scratches affecting the cornea, conjunctivitis and impairment of the vision. In the worst case scenario, some of the risks may escalate into full or partial blindness. Wearing contacts with the right prescription and lens power, not sharing the devices and never sleeping with them will help minimize the risks of infection.
If you have been diagnose with astigmatism and are looking for contact lenses as a solution, you can ask your eye care specialist to advise you on the best options you can explore to resolve your problem.
