Blue Light Blocking Glasses – 5 Alternatives to protect your eyes

Blue light is abundant in nature and more so in digital devices and LED lights. Blue light induces wakefulness to your mind and makes you alert and active. When you stay in a dark room all day, you feel sluggish.

However, blue light can cause harm to your eyes when you are exposed to it for long hours. These lights also known as high energy visible light can make your eyes strain, fatigue and dry. You might also start having headaches after working for long hours on computers. Another worse side effect of excess blue light exposure is insomnia. These lights disrupt the normal sleep cycle and keep your mind active for long hours. Even when your body and eyes are tired, you have a hard time falling asleep.

To avoid these side effects, blue light glasses help in blocking the harmful blue light and protect your eyes. Most blue light filter glasses with 60-90 per cent are not as effective as the blue light glasses that block all of the blue lights. Specscart’s X-Blue UV is one such blue light blocking lens that blocks 99.99 percent of blue light emission. These glasses are effective in regulating your sleep cycle.

Even if you are not a prescription glasses wearer, you can use fake glasses with blue light blocking lenses to protect your eyes from the computer’s blue light. If you work for long hours on computers, then you should get one for yourself.

What other alternatives can you use for blue light blocking glasses?

1. Blue light Filter Screen

If you are not comfortable using blue light blocking glasses, you can put up blue light filter screens on all your digital devices. These filter screens will block excess blue light from the screen and protect your eyes. Your eyes will not get tired or strained too soon.

However, these filter lenses have one shortcoming that is you can not block every blue light emission. LED lights also emit blue lights. You are exposed to it all day and night. By putting it on the screen will not totally solve your problem. If you have a problem sleeping, then these filter screens won’t be helpful at all. You will need to block every source of blue light to regulate your sleep cycle.

2. Adjust the resolution of the screen

The high-resolution screen emits a lot of blue light emission. You can adjust the screen to comfortable mode. This will help in not letting your eyes strain. Although you will not be able to enjoy the high-resolution screen with vibrant clear colours, you will have a comfortable viewing experience without hurting your eyes.

3. Digital Detox

Transition glasses adjust the shade of lenses according to the light. This can also help with reducing the effects of blue lights. When you are exposed to high resolution, your glasses adjust to give you a comfortable viewing experience. These glasses may be expensive but give you comfortable smooth vision both inside and outside.

5. Amber glasses

5 Easy tricks to measure your pupillary distance (PD)

Knowing the pupillary distance is important to find the right fit of glasses for your face. PD is mostly mentioned in your prescription slip. If you are not a prescription glasses user and you are looking to buy stylish fake glasses or blue light glasses for yourself, then you can only measure it by yourself.

Don’t worry, it’s not some rocket science. All you need to know is how to use a ruler correctly and you can accurately measure your PD.

Easy Trick Number 1

Stand (at least 30 cm away) in front of a mirror and place a ruler over your overhead
Now, close your right eye and place 0 mm on the ruler over the centre of the pupil of the left eye
Next, open both eyes and look straight
Now, close your left eye and trace the centre of the pupil of your right eye. The number above your right eye is your pupillary distance
Repeat these steps a few more time to get an accurate reading. For an adult, PD is generally between 54-74 mm
Those with hyperopia can minus 3 from the result to get the accurate PD

Easy Trick number 2

Ask your friend to take the readings for you. It’s difficult to focus on the small readings on the scale by yourself. Also, when you have a vision defect like hyperopia, then it will be difficult to get an accurate reading. Wearing faulty glasses with the wrong PD can cause you a headache, eye pain, blurry vision. You will also have difficulty in focusing.

Stand still, face straight and look at any object 20 feet away
Your friend will mark the centre of the left eye
Without getting into the frame of your view, your friend need to mark the centre of other eye
Now measure the distance between both the marks to get accurate PD

Easy Trick number 3

This trick is for a glasses wearer.

Stand 30 cm away from a mirror with your glasses on
Look straight
Close your right eye and mark the centre of the pupil of the left eye with a non-permanent marker on your glasses
Now open your right eye and look straight
Close your left eye and look straight
Mark the centre of the right eye with a non-permanent marker
Now remove your glasses and measure the distance

Easy Trick Number 4

Instead of measuring PD, find your dual PD. For most people, the distance between the centre of one eye to the nose bridge is not the same for both sides. For such asymmetrical faces, a single PD will not be an accurate reading. This will hinder their viewing. For such cases, a dual PD will be accurate.

Face a mirror at least 30 cm away and look straight
Place a ruler above your forehead and mark the centre of your left eye
Now measure the distance between the centre and your nose bridge
Repeat this for your right eye

You will get a result like 32 for the right eye and 30 for the left eye. In prescription slips, it is written as 32/30. The first number is OD (Oculus dextrus meaning right eye) and the second number is OS (Oculus Sinister meaning left eye).

If both the numbers are the same, then a single PD would work. If both the numbers are not the same, it will hinder your vision. Hence it is necessary to take dual PD to make your glasses.

Easy Trick Number 5

Finding the centre of the eye or focusing on looking straight while marking is a bit difficult task to do. Also, if you cannot take help from any friend, then try out this trick.

Stand still in front of a mirror at least 30 cm away
Instead of locating the centre of the eye, place the 0mm mark at the left end of the left eye
Now measure to the left end of the right eye
To cross-check, place the 0-mark on the right end of the right eye and measure till the right end of the left eye.

A do-it-yourself method is affordable methods but not really reliable. There is room for a lot of errors if you are doing it by yourself. Also, taking the help of others who are not professional is also not a viable option. Your friend may have a vision defect or they did the task sloppily. Anyway, you will suffer from your faulty glasses.

Get an eye test to get an accurate reading. Nowadays, you can avail free eye test while buying glasses. With NHS you can get a free eye test in the UK.

You can even get an eye test at your home or your place of work. You don’t need to take out time to schedule an eye test. Just schedule a time to get an eye test wherever you are comfortable and available.

How does blue light blocking glasses help with eye fatigue?

Computer vision syndrome and blue light blocking glasses are known to work effectively with each other. But before we dive into the working of blue light glasses, let’s dig deep into computer vision syndrome caused by blue light. Computer vision syndrome (CVS) is an umbrella term for the combination of eye and vision problems often caused by blue light rays that are emitted from the digital screens of computers, smartphones, and so on.

Recent research on the study of blue light highlights that a normal individual is exposed to screen for more than 10 hours a day.

Have you experienced eye problems while staring at a screen? If yes, did the blue light exposure make you feel difficult to focus, causing dry or watery eyes, headaches, dizziness, neck pain and sore, tired and burning eyes?

What causes computer vision syndrome?

Computer vision syndrome or Digital Eye Strain is often due to poor lighting, improper sitting posture, uncorrected vision problems, and prolonged exposure to blue light. In a lot of situations, blue light exposure is one of the biggest reasons for computer vision syndrome. Medical News Today also claims that people who work on their computer have a low rate of blinking, resulting in dry eyes.

The main culprit to all these problems is blue light rays to which our eyes are constantly exposed daily.

How is blue light harmful?

Not all the blue light is bad, the natural blue light emitted from the sun is quite helpful. Blue light from the sun helps to enhance dopamine, serotonin, and cortisol that’s required for your healthy well-being. However, it’s not the same blue light that causes numerous eye problems, sleep issues, obesity and other physical changes. Blue light rays emitted from smartphones, laptops, office lights and TVs are artificial which when overexposed to you, result in severe vision changes and health issues.

Artificial blue light rays not only cause eye problems but also disrupt your healthy sleep routine. Blue light exposure into our body ceases the secretion of the sleep-inducing hormone, melatonin. Which tricks our brain to tell our body clock to think of the night as daylight, thereby depriving you of quality sleep at night. Blue light manipulates your brain into thinking of the night as daylight, and making you alert, active and awake.

It’s not at all healthy to use digital devices after sunset as it sends wrong messages to your brain, resulting in sleep deprivation, mood disorder, depression and high anxiety. You are exposed to blue light when you switch on your TVs at night, our check your last email on your smartphone.

What happens when you wear wrong prescription glasses

Wearing glasses has become normal. Where most people wear them to see clearly, there are people who like the fashion appeal that this accessory gives.

If you are from the latter category, you need to choose frames that suit your face shape, skin tone, hair colour and personal style. For example, cat eye women’s glasses for a round face. But, if you are someone who wears vision correction glasses, you need to make sure that you have the right prescription.

People with refractive errors are required to use glasses for vision clarity. Whether you are buying your first or fifth pair, make sure you buy glasses with the right prescription.

Your ophthalmologists or optometrists are only human. It is quite normal to make mistakes no matter how long you have been into your practice.

Signs that your prescription is wrong

Our vision changes throughout our lives. If you want to give up your old prescription glasses, make sure you visit your eye doctor to know if your optical power has changed. Although using wrong prescription glasses won’t cause any severe damage to your eyes, it can invite some visual and physical discomforts which are not worth suffering through.

Headache, nausea, dizziness or vertigo are some unpleasant side effects of using wrong glasses for your particular eye problem. Even when you order glasses online, be extra careful and enter the right prescription along with other useful information such as pupillary distance.

You don’t have to make a trip to your eye doctor to know if you are using the correct prescription, your eyes will let you know. However, if you are not accustomed to glasses or your prescription has recently changed, feeling dizzy is normal. Where some people take 2 to 3 days to adapt to their new spectacles, others might take up to two weeks.

Types of refractive errors

Different refractive errors target different parts of your eyes. Here are some vision problems that one can develop.

1. Myopia or Nearsightedness

In myopia, the length of the eyeball is longer than usual which causes the light to refract in front of the retina rather than focusing on the retina. People who are myopic are able to see close objects clearly but have a blurred vision when trying to spot distant objects.

If you have myopia, you can wear single vision lenses to get a clearer view at distance. Prescription eyeglasses are generally costly as they have specialised lenses with different focal powers. If money is a constraint for you, buy online glasses at affordable prices without going low on the quality.

2. Hyperopia or Farsightedness

Contrary to myopia, hyperopia occurs when the eyeball is too short that the light is focused behind the retina causing the eyes to lose their near focal ability. However, hyperopia is not the same for everyone. For example, sometimes the distant objects can be viewed clearly while other times people may have blurred distant vision.

Even if you have a 20/20 vision, you might want to consider wearing non-prescription glasses with protective coatings such as Anti-UV, Anti-Glare and Anti-Scratch. At Specscart, you will get these coatings for free on every pair of glasses that you buy.

3. Astigmatism

Astigmatism can be resulted from an oddly-shaped cornea. When your cornea is not round but rather shaped like a football, the light gets focused in front or behind the retina and thus your vision becomes blurry at any distance. People with astigmatism generally have distorted vision at every distance including near, intermediate and far. If you are a man with astigmatism and above 40, your eye doctor will most probably recommend men’s glasses with bifocal lenses to work on your vision difficulties.

4. Presbyopia

It is an age-related problem in which the crystalline lenses inside your eyes start to lose flexibility and become incapable of focusing on nearby objects properly.

People often confuse presbyopia with hyperopia but they are not the same. High hyperopia may even cause your eyes to have blurred vision when looking at far distances. In such a case, people with hyperopia will benefit from varifocal glasses that will give them vision clarity at all distances.

Side effects of wrong prescription

It becomes important to not only identify your particular eye problem but to also figure out the magnification strength or optical power you will need for your glasses.

When you have given an eye test, your optometrist will give you the latest prescription so you can get your lenses made or order glasses online using the right prescription. The correct optical power will work on your specific vision problem so the things around you are not a blurry mess.

However, if you act careless and buy glasses without consulting your eye doctor, these are the side effects that might come your way.

1. Headache

Have you ever worn somebody’s glasses and had a headache?

Excruciating pain in your head and eyes are the most common signs that must alarm you to check your prescription glasses. If you have frequent headaches for some days after you have started wearing your new eyeglasses, it is time to make a trip to your optometrist.

Your eyes work hard to adapt to a new prescription and when the prescription is wrong, they will work extra hard and wear themselves out in the process.

2. Vertigo

Vertigo is not just dizziness. It is the feeling of dizziness that does not go even when you lie down. Blurred vision is also a cause of vertigo but wearing glasses with the wrong prescription will make the situation only worse.

If you don’t have vertigo or if it has become worse with your new glasses, see your doctor and get your prescription fixed.

3. Blurred vision

When your optical power is off even a few degrees, you might have blurry vision. However, blurriness can also occur while adjusting to a new pair of frames. If the situation remains the same even after two weeks, it’s most likely that you are wearing wrong glasses.

The Final Word

We trust our optometrists but they can also make mistakes while taking your eye measurements leaving you with the wrong prescription. The next time you visit your eye doctor, make sure to notice how well you are able to see after your glasses fitting. If you like to buy online glasses, pay close attention to the prescription as well as the fitting.

Your eyes have a way of telling you that something is wrong with your optic health. If you have any questions about your vision difficulties, talk them out with your eye doctor or optometrist.
