Also known as digital lenses, refers to the advance manufacturing lenses for glasses that uses computer-managed technology and surfacing to create high-level, customized eyeglass lenses with your unique prescription.
What is the difference between conventional and digital lenses?
Conventional or traditional lenses were produced with a multi-step, labor-intensive process that required much more time and multiple pieces of equipment to produce a lens.
Visión with conventional lenses can be clearer in the center of the lens but as your eye looks away from the center or toward the periphery, your visión begins to get blurry.
Digital lenses are computer-controlled surfacing equipment that uses precise scanning technology. This technology is much more precise than conventional tools. Therefore, image quality is more superior.
Advantages of digital lenses
- Sharper image quality
- Improves intermediate and peripheral vision.
- Improves contrast sensitivity
- Reduce glare for night time driving
- Customized for specific prescription and frames

Do you wear glasses and are familiar with the struggle of dealing with the sun. You have to switch over from both your glasses and sunglasses wherever you go. Perhaps a manageable option is to wear glasses with photochromic or “transition” lenses. These special lenses darken in the sun, outdoors, then lighten up when you are indoors.
Photochromic lenses are optical lenses that darken on exposure to particular types of light of adequate strength, most commonly UV the radiation. Without light, the lenses return to their normal clear state. Photochromic lenses may be made of glass, polycarbonate, or another plastic.

Progressive lenses are multifocal lenses with progressive addition power that changes from top to bottom. Multifocal Lenses have three viewing areas, each one provides clear vision at distance, intermediate and near.
Many people confuse the terms “bifocal” or “trifocal” with “progressive,” but it is key to remember that bifocals and trifocals have a visible line in the lens, while progressives are line free.
Who needs progressives lenses?
Usually prescribed for people over the age of 40. As a normal part of aging our vision tends to progressively decline. Consequently, we develop presbyopia. Intermediate and near objects are difficult to see and we need different glasses to view at different distances. Progressive lenses provide visión at different distances all in one lens.
What are the advantages of progressive lenses ?
For most people, progressive lenses are more beneficial than traditional bifocals or trifocals lenses since they:
- Eliminate image jump caused by bifocals and trifocals
- They work in smaller frames, helping you keep up a youthful appearance.
- They provide a more natural view for people suffering from age-related vision loss.
- They provide clear vision on objects at any distance.
- They provide more comfort for active wear.
What are the disadvantages of progressive lenses?
- Takes some adjusting to, however it doesn’t take long.
- There may also be some distortion of your eyes on the edges of the lens.
- Progressive lenses cost more than traditional bifocals and trifocal lenses.
Tips on adjusting to progressive lenses.
- Point your nose at any object you’re trying to focus on, then tilt your chin until the object comes into focus.
- Use the top of the lens for distance and the bottom for reading.
- If you need to look at the floor, tilt your head and look through the top of the lens.
Don’t be worried. Adjusting to the lenses can take anywhere from a few days to several weeks to get used to, but once your eyes are adapted it to them, it will be worth it!

What is Blue light and why is it harmful to the eyes?
Blue light is a color in the visible light spectrum that cannot be seen by human eyes. Light travels in waves and is measured in wavelength. A short-wavelength produces higher amounts of energy. Blue light is a short wavelength, therefore blue light is harmful to the eyes.
Blue light sources:
- Natural blue light from the sun
- Artificial LED and fluorescent lighting
- Artificial digital blue lights from laptops, tablets and mobile devices
How does blue light affects the eyes?
- This high energy blue light penetrates the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular. Prologue exposure to blue light causes toxicity to the retinal cells. Causing irreversible damage and permanent vision loss.
- Blue light from electronic devices reduces your visual contrast, affecting clarity and sharpness to your vision. It can cause eye strain, physical, mental fatigue and headaches.
How does blue light affect our sleep patterns?
Not all blue light is bad. Proper and timely exposure to blue light during the day helps the body maintain wakefulness and also contributes to our sleep-wake cycle which plays a vital role in mood and overall general health.
Overexposure to natural or artificial blue light reduces the production of sleep-inducing melatonin hormone by the brain. Melatonin is a natural hormone made by a gland in the brain. During the day this gland is off but when the sun goes down the gland activates. In dark conditions, the gland starts releasing melatonin and you start feeling sleepy.
Electronic devices emit artificial blue light that interferes with the body’s natural internal clock (sleep.org) or a circadian rhythm that signals when it’s time to sleep and wake up. The more time we spend in front of an electronic device, especially in the evening, the greater the delay in the release of melatonin, making sleep more difficult at night.
How to protect the eyes from the harmful blue lights?
- Eat foods that are high in lutein and zeaxanthin : spinach, kale, leafy greens, Pee shots.
- Wear photochromic lenses, which provide protection from UV and blue light both indoors and outdoors.
- Position the computer screen to avoid glare. Try to keep window light off to the side, rather than in front or behind you.
- Follow the 20x20x20 rule : every 20 mins give your eyes a rest by looking at something 20 ft away for 20 seconds.
- Make an effort to blink frequently. Blinking keeps the front surface of your eye moist and prevents dry eyes.
- Turn Night Shift mode on or manually or create a custom schedule or your Iphone or Ipod to reduce the amount of blue light your device emits
- Try not to use your devices directly before bedtime.
Digital devices can be an entertaining and helpful tool but they don’t have to harm your eyes.
Proper viewing habits and protective lenses can reduce the exposure to blue lights. We offer a range of products design to filter blue light.
Ask our Dr. Dussan about our different options.
