(ThyBlackMan.com) Astigmatism is a fairly common eye condition that requires a specific type of lens, and while contact lenses are already a very personalized medical device, this condition takes it a step further. If your eye care professional has determined that you have astigmatism in either one or both of your eyes you will then require a toric lens over the typical contact lens. This particular type of contact lens are usually available with brands you trust. For example, Acuvue Oasys for Astigmatism toric lenses by Johnson & Johnson can be easily found online and are shaped to comfortably suit someone with this type of vision correction need.
What’s Astigmatism?
Before delving into the actual toric contact lens from www.contactlenses.co.uk, let’s briefly go over what astigmatism diagnosis means. This type of condition refers to how your eye is able to bring a single focus to light rays. Your retina is the area in your eye that receives and processes light, so if there are multiple points in your retina that are trying to process these rays then the end result will be a disruption in vision. Unlike nearsightedness or farsightedness, astigmatism will cause this issue in sight at any distance.
In addition to the retina’s ability to process light, astigmatism also result from the curvature of your cornea. If you have astigmatism then instead of your corneas being round, they will be more oval in shape like a football and will require the specially shaped toric lenses. Due to this shape of the cornea, your vision will seem distorted, objects seeming almost wavy in appearance, and will most likely be blurred.
Side Effects
Along with blurred or distorted vision, another tip off for astigmatism is headaches that are caused from putting too much strain or stress on your eye. If you notice that you are consistently experiencing headaches after visually taxing tasks like using a computer for a long time or reading, then you could potentially have astigmatisms in either one or both of your eyes. Another symptom of astigmatism that is due to vision impairment at all distances is squinting, so if you find yourself squinting a great deal then you may want to schedule an eye exam.
Typically toric lenses that are prescribed for astigmatism are a soft contact lens. Since astigmatism affect vision at all distances, toric lenses account for this by having different degrees of power in the different meridians of the lens unlike typical spherical lenses which have the same degree of power in all meridians. Toric lenses even have the unique ability to adjust itself on the cornea so that the correct power adjustment corresponds with the meridian in the eye where the vision correction is needed. This is a highly personalized contact lens, so it may take some trial and error in order to find the best brand and fit that works for you. Toric lenses are widely available from many different manufacturers and brands such as Johnson & Johnson’s Acuvue Oasys for Astigmatism or CooperVision’s Biofinity Toric.
