Can Wearing Glasses Improve Your Vision?

Yes, wearing glasses can improve your vision. Glasses clarify and enhance what you can see—but the better vision that comes from wearing glasses is thanks to a change in your perspective, and not the result of any actual changes to your eye or eyesight. Glasses can counteract and correct physical anomalies in the shape of your eye that impact your ability to process light properly, which in turn harms your vision. While glasses are a helpful tool to bridge that gap, they do not actually help your eyesight get better.

Why Do You Need Glasses?

Simply put, glasses help people see better, and they can be used to counteract eyesight problems with distance and/or clarity. You can improve many visual issues and conditions by wearing prescription glasses. For many eyeglass wearers, this leads a much higher quality of day-to-day life.

The physical nature of your eye is directly related to the type of vision problems you’ll face, and helps identify the proper type of glasses to improve your vision. Nearsightedness and farsightedness are the most common visual impairment issues people face. Nearsighted refers to someone who can see things close to them well, but who suffers from fuzzy vision at a distance. In this scenario, the physical length of the eye is too long, which causes the distortion. In contrast, far-sightedness results from an eyeball that is too short, making it difficult to read and see things close-up. Wearing prescription glasses significantly improves both of these conditions.

Furthermore, glasses can be useful during specific activities, like reading, writing, or driving.

Will Wearing Glasses Weaken Your Eyes?

Glasses can improve your vision—but, just like they can’t strengthen or improve your physical eye to fix your eyesight, they are also not going to weaken your eyes if you wear them. Prescription eyeglasses are optical aids that change the way your eye receives light rays to improve visual clarity. This results in a better overall visual experience. Wearing glass does not increase or decrease your actual eyesight and vision strength.

Can Wearing Glasses Improve Your Vision?

If you are having trouble seeing in different scenarios, your eyesight can get better if you wear glasses. Glasses are an excellent tool to help improve your vision, but you must use them consistently as an aid. They cannot “fix” any medical issues or make significant changes to the structure of your eye, so the result of wearing glasses is a temporary boost in your overall visual perception.

Photochromic lenses

Have you ever wondered how Transitions® lenses work? The magical mash-up of sunglasses and eyeglasses, when you see them change color, you feel like – the future is now. Transitions® are an example of photochromic lenses.

Some other names for photochromic lenses are Light Adaptive, Variable Tint, Photochromatic, but many people call just them by the popular name brand Transitions®; you could say they’re the the “Kleenex” of photochromic lenses.

If we start with the etymology of the word, photochromic comes from two Greek words; photo meaning light and chroma meaning color.

Photochromic lenses change color when exposed to light.

You can get clear photochromic eyeglasses that change all the way to dark sunglasses, or photochromic sunglasses which are just for outdoor wear (and do not get completely clear.)

So how do Transitions® lenses work? When exposed to light, the photochromic molecules in the lenses begin to change structure, like in the illustration below. This new arrangement allows the molecules to absorb more light which causes the lenses to darken. Most photochromic lenses to UV light; that’s why they change when you’re in the sun yet remain clear indoors.

how do photochromic lenses work

Temperature also has effect on the reaction time of the molecules in photochromic lenses. On a cold day, your lenses will react more slowly than on a warm day.

In this video, one of FramesDirect.com’s expert opticians, Travis, explains further:

 

Transitions® lenses continuously adapt to changing light conditions and block 100% percent of harmful UVA and UVB rays. Having your lenses give you the exact amount of protection you need to see clearly, means your eyes are doing less work. And there’s the added benefit of only having one pair of glasses for indoors and out!

safety glasses

Safety glasses: For Work, Hobbies, and with your Prescription

Safety glasses have come a long way. You used to have to buy big goggles to put over your prescription glasses, which were cumbersome and could get quite foggy – making your work even harder. Whether you need prescription lenses, or not, safety glasses are a lot less bulky these days.

Even with a streamlined look, safety glasses should (of course) protect your eyes from whatever hazards you may encounter.

The best way to ensure your safety glasses will give you reliable protection is to purchase frames and lenses that are ANSI rated.

ANSI stands for American National Standards Institute; they have minimum performance requirements for glasses and put frames and lenses through a series of tests – including a high velocity test conducted with a ¼ inch steel ball!

Whether you’re buying safety glasses (or prescription safety glasses) for work on a construction site, a laboratory, or for your kid to wear to play in a baseball game, the standards are the same. At FramesDirect.com we carry multiple brands of ANSI rated safety glasses and goggles, so you can find the the perfect pair for any activity. And if you buy prescription glasses in a safety frame, we will fit them with polycarbonate lenses that are ANSI rated. Polycarbonate is the most impact-resistant lens material. A full range of lens options are available including anti-fog and anti-scratch coatings and tinting.

You only get one pair of eyes per lifetime, so if you have a job that puts your eyes in harm’s way or just enjoy some of the more dangerous hobbies, its worthwhile to find a pair of glasses that fully protects them! All our operators at FramesDirect.com are trained opticians, so if you have any questions about getting the best safety glasses for your needs, just let us know.

high index lenses

#FDAnswers: I have a strong prescription. What lenses do I need?

Full disclosure, this post is personal. I have terrible vision. I started wearing glasses when I was about 8 years old. By the time I was 11, I was begging my Mom for contact lenses. This was in the 80’s when high school girls and secretaries in movies would take their glasses off and suddenly be transformed from invisible to gorgeous. Glasses were not pretty – that’s the message I received loud and clear. Thus began a lifelong struggle with glasses, I would only wear them at home, if at all, never in public, and half the time I fell asleep with my contact lenses on. Even as the decades passed and glasses became the fashion accessory du jour, I couldn’t enjoy them. Why? Because my vision is so bad my lenses looked like the proverbial coke bottles, and turned my eyes into blinking little beads.

So that brings us to today. My prescription is -8 in my right eye and -11 in my left. I can’t see ANYTHING without glasses or contacts, but I have found a way to wear my glasses without feeling completely self conscious – three words: High Index Lenses. If your prescription is crazy high like mine, you should get the thinnest possible lens, which is the High Index 1.74. Anything +/- 6 you definitively need them. Another trick I’ve learned is to ask for no edge polish. When your lenses are VERY thick, polished edges call even more attention to them.

Here’s one of our expert opticians, Amanda, talking about the benefits of High Index 1.74 lenses.

 

If your prescription is between +/- 2 and 6, you could get the High Index 1.67 lenses. The 1.74 are the thinnest, but they aren’t available with tinting or progressives, so you may need the 1.67 if you’re looking for those add-ons. The other varieties of lenses – plastic and polycarbonate – aren’t great if you have a prescription that’s +/- 3. High Index lenses are a bit more expensive but well worth avoiding the coke bottle look!

All our high index lenses come with scratch resistant and UV coatings for no additional cost. You can learn more about all the lens types we offer at FramesDirect.com here.

#FDAnswers “What does polarized mean?”

Polarized sunglasses are desirable (and slightly more expensive,) because most people know they can greatly improve your vision in bright sunlight. Polarization, when referring to optics, is more than a buzzword or a marketing term. There is science behind why your eyes feel more comfortable, and you see more clearly, when wearing polarized sunglasses. But what does polarized mean?

Glaucoma Awareness

January is Glaucoma Awareness Month

January has been declared National Glaucoma Awareness Month by Prevent Blindness and other leading eye health organizations, in an effort to help educate the public on the disease. Glaucoma is a group of conditions that damage the optic nerve, the bundle of nerve fibers connecting the eye to the brain, and is the leading cause of preventable blindness.
