Believe it or not, but today, almost everyone is a victim of Computer Vision Syndrome (CVS), a condition which results from focusing the eyes on a computer or any gadget for prolonged hours. Continuous working on digital screens means focusing and refocusing your eyes back and forth. This leads to eyestrain, dry and sticky eyes. Also, the impact of blue light emitted from digital devices is such that your eyes may have serious and long-term effects on your eyes. But, no matter how much you are used to a modern lifestyle and how much you enjoy working on laptops, tablets, mobiles and computers, it poses a threat to your eyes. Hence, it is recommended to use lenses with blue cut filter coating for a comfortable vision.
Blue Lenses are made with a revolutionary material which by virtue of its material property absorbs harmful UV rays and high energy Blue Light. It is a neutral color-balanced substrate, blended in the lens material while the lens is casted. It is completely normal for lenses to develop a slight tint of yellow over time. It doesn’t alter the inherent properties of the lens material, but ensures a comfortable vision and enhanced protection to the eyes by absorbing UV and high energy Blue light entering the lens.
The blue cut filter coating in Pellucid Blue Lenses cut down the harmful UV rays completely along with a major portion of HEV blue light, protecting our eyes and the body from potential danger. These lenses offer sharper vision and reduce the symptoms of eyestrain that are caused by a prolonged computer exposure. Also, the contrast is improved when this special blue coating reduces screen brightness so that our eyes face minimum stress when exposed to blue light.
Anti-glare blue cut lenses protect your eyes from the harmful effects of blue light caused by prolonged working hours on a computer, laptop or mobile.
Blue light coating is a special coating which works by reflecting high energy blue light and restricting it from entering into the eyes. This coating or blue light filter blocks the harmful portion of blue light and allows the healthy portion of blue light to pass through your eyeglasses lenses.
Blue light filter is ideal for people who work on digital devices for prolonged hours. By restricting the blue light from entering into the eyes, it helps reduce the symptoms of eyestrain (dry and sticky eyes) resulting from screens of digital devices. Also, lenses with blue cut coating offer a comfortable vision and may improve visual performance in low color contrast.

Since blue-cut lenses absorb harmful UV rays and high energy Blue Light, a slight yellow tint may develop over time. This is completely normal and does not affect the efficiency of the lenses at all.
“Regular plastic” eyeglass lenses refers to what is known in the industry as “CR-39 plastic” lenses. Regular plastic lenses have better visual clarity than the thinner polycarbonate or high index lenses, and they are less expensive. For low prescriptions, regular plastic lenses are usually the best choice for prescription lens material. However, regular plastic prescription lenses also have some drawbacks and limitations in certain situations. For example, if your prescription is higher than +/-3.00, the regular plastic lens will become thicker and heavier, and you could benefit from moving to a polycarbonate or high index lens. Also, if you have a three piece rimless eyeglass frame, you should not use a regular plastic lens because it is likely to crack under the strain. Finally, children and sporting adults are recommended for polycarbonate or high index lenses because they offer better eye protection than regular plastic lenses.
If your prescription is higher than the +/-3.00, you may want to look at a higher index (and more expensive), thinner and lighter lens. CR-39 is the standard type of plastic used for everyday use, around the office, or for shopping. These lenses have the least distortion of any non-glass lens. For children or active adults engaged in sporting activities, we strongly recommend polycarbonate (impact resistant) lenses. If the sphere on your prescription is +/-2.00 or lower, you will not benefit from the more expensive thin high index lens types. If the sphere on your prescription is higher than +/-2.00, you will benefit from the selection of a “thin” lens type. If the sphere on your prescription is higher than +/-3.00, we recommend a ‘thin’ lens type. Thinner lenses have three advantages: they do not look ‘thick’, they do not magnify or minify your eyes when seen by others, and they are lighter.
Progressive lenses, have no lines separating the different lens strengths, yet they provide the user with clear vision at all distances, allowing both head and eyes to stay in a natural and comfortable position when looking at objects in the distance, the intermediate zone and close up. This means no abrupt changes in lens strength, and no need to compensate with unhealthy body movement patterns.
The results are, rather, simple and seamless. Eliminating the visible line in the middle of the lens also hides the fact that the user is in need of reading glasses, something many is self-conscious about.
Progressive lenses are designed so that a smooth and seamless progression of lens power runs vertically down each lens, providing clear vision at all distances and a more natural depth focus than bifocals.
Choosing lenses with anti-reflective coating will eliminate reflection on both sides of the glass, making activities like driving in the dark a more pleasant experience. This will also help others see your eyes clearly.
Although this is currently the peak of eyewear technology, it is impossible to create seamless multifocal lenses without the occurrence of unwanted aberrations, or irregularities creating distorted vision somewhere in the lens. These aberrations might cause the peripheral vision to appear slightly blurry, especially when looking down, or create a “swim effect” (the sensation of being out of balance) during rapid movements of the head. For most people, these are minor issues that disappear as they get used to their new lenses, and technological advances in the development of progressive lenses have eliminated or minimised most of these negative side effects.
To make sure that the lenses are tailored to your specific needs, your eye-care specialist will measure your eyes and eyeglass frame in order to carefully adjust the lenses to suit your eyes. Today we have a wide range of progressive lens designs to fit almost any need and lifestyle.
There are many conditions that can affect our eyes, including overlapping conditions that can cause discomfort and poor vision. Progressive lenses help correct many of these problems, as well as remove discomfort.
Here are some of the reasons why progressive lenses are required:
The development of presbyopia often occurs around the age of 40 and causes blurred near vision. Progressive lenses are the most widely purchased lenses for correcting this condition.
Progressive lenses can also reduce the progression of myopia, and can correct astigmatism.
Progressive lenses are recommended for people in need of correction of near- and distance sight.
Adaption time for progressive lenses can range from minutes to days, depending on your specific vision problem. Consult an eye doctor or optician for tests and personalization of your lenses.
Getting your eyes checked regularly is an important investment, both in your current and future health. Visit your eye care specialist today to determine if you have any undiagnosed eye conditions or if you need glasses, and which lenses are most suitable for you.
Regular sunglasses block out particular wavelengths of light with either coloured filters or polarisation. As photochromic lenses are carbon-based, the molecules react to UV; they change shape and absorb the light, meaning the lenses start to look darker. The more UV rays there are, the darker the lenses will become. They adapt accordingly from clear through to different darker shades, depending on the levels of UV. The darkening can take up to 30 seconds for the tint to take effect on the glasses, and it can take between two to five minutes to return to normal when going back indoors.
They protect from UV rays, which helps your general eye health. Made from either plastic, glass or polycarbonate, photochromic lenses are available as different prescription glasses for people who have eyesight difficulties. Plastic photochromic lenses are often favoured over glass due to their molecular make-up; users often find the tint on plastic lenses to be more evenly distributed than on photochromic glass lenses.
Photochromic lenses can be worn all day every day, just like normal glasses. Anybody can benefit from them, but especially those who regularly interchange from indoors to outdoors.
Photochromic glasses can be particularly good for children who are unlikely to be able to juggle two separate pairs of gasses – regular and sunglasses. It also helps their eye health from an early age by protecting them from the sun and UV rays.
