The eye is the most important sensory organ, but even today medicine has not found a way to prevent the natural deterioration of vision.
While the battle between contact lenses v/s glasses continues to pique interest and gain a following on either side, simply put, some people prefer glasses and don’t see the benefits in contacts. While others discover great convenience from contact lenses and like to believe that they make them look more attractive!
How about we demystify this for you? (Pun intended)
Contact lenses are thin, finely crafted plastic discs designed to fit over the cornea of the eye, usually to correct vision problems caused by refractive errors. They are held in place by adhering to the tear film that covers the front of the eye. While their cosmetic advantages are obvious, contact lenses provide better peripheral vision and virtually eliminate the image distortion sometimes caused by spectacles.
Your eyes speak volumes
Have you ever wondered how you would feel if your eyes were gifted with colour? A light green or a deep blue perhaps? Contacts are given an enhanced tint, which can alter your eye colours for a beautiful natural look. The most commonly adorned contacts are the ones with colour tints, and they are all the rage.
With the advent of colour lens, youngsters are also given an option of wearing theatrical contact lens to make the eye appear unnatural. Whether it was Linda Blair (Regan) in the Exorcist or one of those ghastly things on horror shows, add some shock and thrill to your life with just a pair of costume or theatrical lenses!
However, you must invest time in determining the purpose of wearing lenses and the duration you plan to keep them on. So, pick a lens of quality, for it involves the health of your eyes.
At Your Disposable
Disposable contacts are a breakthrough in the field of eye care products and are recommended by most practitioners. Your tears contain substances such as proteins, calcium, and lipids and these are deposited on your lenses, leaving your eyes prone to infection. Hence, frequent disposing and regular cleaning reduces the risk of infection and/or swelling.
Tech behind your lens
Technology has made production of high-quality lenses cheaper and more scalable.
AI Optics Ltd., Chennai manufactures intraocular lenses (IOLs). IOL is a medical device with optic and haptic components, used in the visual correction of cataract. The lenses are cut on lathes from PMMA (Polymethyl methacrylate) or HEMA (hydroxyethyl methacrylate) blanks with UV absorbing properties.
The manufacturing of IOLs involves a 25-stage process, which includes the preparation, characterisation and fabrication of intraocular lenses.
Compressed air is used as an air bearing system, where the spindle is suspended in the air and a natural diamond tool is used for cutting the lens. The air-bearing system needs a clean, dry air supply, free from solid, liquid, and gaseous impurities. AI Optics utilises both refrigerated and heatless dryers for condensing the moisture. Compressed air is vital to the production process, and the portable air compressors run round the clock, seven days a week at AI Optics.
