Unfortunately, wearing glasses comes with a slight adjustment period. Most people will experience headaches and sore or tired eyes during the first few days. However, as your eye muscles get used to relaxing instead of working so hard to make sense of what you are seeing, the headaches and soreness will disappear.

In the majority of cases wearing your glasses in an increasing amount will not harm your eyes. Whether it's prescription glasses, or a specific set of lenses for corrective vision, wearing your glasses for more extended periods won't hurt your vision.

If you're experiencing eye strain, that can also cause headaches and nausea. Taking breaks from your glasses as your eyes adjust can be helpful. In most cases, headaches go away naturally in just a few days. Start by wearing your glasses for an hour or two at a time and work up to wearing them all day.

It can take a few days to a few weeks for your eyes and brain to fully adjust to your new eyewear, whether you are increasing your prescription or wearing eyeglasses for the first time.

You could experience worsening myopia symptoms or more trouble seeing up close. That means your prescription may change over time. Glasses help correct your vision. If your prescription changes, your glasses will no longer correct your vision and can cause more vision and health problems.

When your prescription is too high, you will notice that you begin to feel dizzy and nauseous within some time of wearing your prescription glasses or lenses. This is a sure indication of a wrong prescription.

There's no hard and fast rule of how often you need to replace your prescription glasses, although most optometrists recommend you do so every one to three years. If your vision hasn't changed and your glasses are in good condition, you may be able to keep the same pair for a long time.

your exact prescription proportions. Throw in extra lens coatings like UV-protective, anti-reflective, photochromic and scratch-resistant coatings — plus the time it takes to be delivered — and you've got a roughly 2-week process.

Wearing your glasses will encourage your eyes to get used to the changes and adapt to the vision correction. Put your glasses on and wear them as soon as you wake up in the morning—that's when your eyes are fresh. Continue wearing them as much as possible during the day.

If you are feeling mildly off-balance or dizzy when you first wear your new prescription, don't panic it's normal and pretty much everyone goes through it. We recommend not to plan long-distance driving or strenuous activity during your first few days with your new prescription.

You should get the written prescription, following the eye examination, from your optician. After that, you are free to take the prescription to any other practice.

Prescription glasses can improve vision in all lighting conditions. On their own, they may improve night driving. Adding an anti-glare, or anti-reflective (AR), coating to your eyeglasses can allow more light in and also cut down on glare.

Checking whether your glasses have an anti-reflective coating on them or not is relatively simple. When you hold your glasses, tilt them this way and that and look for glare. What you will see if you have an anti-reflective coating is a bit of glare, but mostly a greenish and pinkish color.

Anti-glare (AG) or anti-reflective (AR) lens coatings are specific coatings designed to decrease the amount of reflective light in your lenses. These coatings can be applied to the back, front, or both sides of your lenses to control the amount of light that enters your eyes.

The best tints for driving are grey, amber, and copper-tinted lenses because they maintain color distinction. Light green, blue, red, and pink can distort important colors, which are crucial for seeing traffic lights.

In short: anti glare coatings will protect against external light sources entering the glasses, while anti-reflective coatings will protect against both internal and external light.

Wearing eye protection glasses while you are working is ideal to protect your eyes from blue light exposure and to prevent the associated symptoms.

Wearing the wrong prescription for a prolonged period of time can cause eye strain, resulting in pain around and behind the eye. People often compare this pain to a headache.

Most eyeglasses are designed to optimize distance vision — usually defined as 20 feet away and beyond. Most bifocals and reading glasses are designed to give focused vision — about 14 inches from the eye.

You'll know if you need distance glasses by looking at the Sphere boxes on your prescription paper for each of your eyes. If they contain negative numbers (-) this means you are myopic and require optical correction for distance vision.
