In the past few years, eyeglasses have redefined their stature as a fashion accessory. It’s now more than just a corrective instrument for your vision. While you’re probably meticulous in choosing the design and the brand of your frame, you must leave the choice of lenses to chance. These are, after all, the most essential part of eyeglasses.
The retailers from For Eyes Only mirrored this notion, saying ‘The quality of lenses, are as, or if not more important than the quality of the frame you put them in. There is a solution for every correction.’
Over time, the lenses also underwent a series of technological advances. They were only made of glass before, but now optometrists present lenses made of high-tech plastic material. It weighs much lighter than real glass and doesn’t break as easily. Plastic lenses usually come with filters that block off UV radiation.
Types of Lenses
The size and shape of lenses depend on your visual problem. For instance, the lens is curved outward to correct farsightedness, while it’s curved inward for nearsightedness. If you have astigmatism, which is caused by warps in the cornea’s shape, your optometrist may suggest cylinder-shaped lenses.
If you have more than one vision problem, you can use multifocal lenses. This can be a combination of at least two lenses to correct your eyesight simultaneously. These lenses are those which have separation lines on the side. But with recent developments, optometrists now make multifocal lenses that look unified.
There are numerous types of lenses, such as bifocal and trifocal, photochromic, aspheric, polycarbonate, polarised, hi-index, and progressive. Each of these types features different advantages that are suitable for specific cases. You can also add coatings such as anti-reflective and scratch resistant.
In spite of the remarkable durability of glass materials used for making lenses, there are still some issues that almost always seem to come about. Optometrists developed eyeglass coatings as a solution to these problems. Your lenses can be coated with anti-reflection, scratch-resistance, mirror lens, and tint or transitional.
Eyeglasses function as your second pair of eyes. Take good care of them just as much as you would your eyes. Clean them with a lint-free cloth and store them in a clean place.
