Eyes are sensitive and sophisticated organs that highlight the ingenuity of human anatomy and how it is designed to work as a small world within itself. It can transmit and process multitudes of visual data into impulses that drive action and reaction. Treating eye diseases, therefore, is an elaborate and careful process that requires focused examination and tailored treatments for the one afflicted. With the kind of lifestyles that most people are adopting, exposing their eyes to harmful digital light waves which are beyond the scale of a human eye is designed for, it is imperative that eye care providers and makers design products that can adapt to these changes.
An eyesight condition like Astigmatism can be troublesome for the average person as it can interfere in daily activities such as driving, working, and focussing on objects. It is treatable as it arises from a curvature deformity in the eye, therefore one can invest in corrective lenses or invasive refractive surgery to treat it. A favoured solution for the same is the use of Toric contact lenses which define the blurred planes on the wearer’s vision and can be a great alternative to surgery. Let us understand how toric contact lenses can be made useful.
Astigmatism
To understand the benefits of toric contact lenses for corrective eye care, one must understand how they benefit patients with Astigmatism. The condition of Astigmatism can be defined as a refractive fault or lapse caused by problems in the shape of a person’s cornea.
The cornea of a person without Astigmatism is shaped like a symmetrical round shape, but for those with the condition, the cornea is more egg-shaped. If the cornea were divided by two meridians across each other, a way to understand Astigmatism would be to note that one meridian is more curved than the other. Astigmatism can also occur due to a deformity in the shape of the lens inside the eye, but it is rarer than its more common corneal condition.
The result of this corneal deformity leads to the patient being unable to accurately focus on lights, as the retina fails to equally focus leading to a blurred or linear appearance of the light. One may develop this condition along with Myopia (near-sightedness) or Hyperopia (far-sightedness) and it can be easily diagnosed with the help of a standard eye examination. It is important to note that Astigmatism is a refractive problem and not an eye disease.
Toric Contact Lenses for Astigmatism
Since contact lenses have become highly equipped to correct all kinds of eyesight problems today, an example of the same can be found in toric contact lenses. As aforementioned, toric contact lenses are designed keeping in mind the deformed cornea so it can correct the refractive error caused by the same. Toric contact lenses are usually soft contact lenses and are made of either Hydrogel or Silicone hydrogel. Often just called torics, these lenses are also available in gas permeable, or hybrid makes which offer a sharper field of vision but are less breathable than the soft toric contact lenses.
Toric Contact lenses are designed to holistically correct all parts of the lens, effectively correcting the near-sightedness or far-sightedness caused by Astigmatism. They are also specially equipped to be able to rotate to the ideal angle for correction when placed on the eye. Since these toric contact lenses are more sophisticated than regular contact lenses, it requires a few tries to find the ideal fit as every eye and corneal deformity can differ from person to person.
One should duly set up a fitting for toric contact lenses and experiment with assorted brands and choose the one that offers the best fit. Owing to the complexity of their design, the maintenance and replacement costs for toric contact lenses are higher than regular contact lenses. Therefore, while browsing for options, one should seek out reputed brands like Titan Eyeplus and their range of corrective contact lenses as they are accessible, affordable, and tailored to your needs.
