Are you confused about what to wear with eyeglasses or contact lenses?
It is not as big a matter as you think.
You can wear both of them whenever you want.
If you think glasses don’t suit you, you can get lenses. On the other hand, if you find difficulty while wearing lenses, get eyeglasses.
But, actually, the main query are contact prescriptions the same as glasses?
Let me tell you!
Precisely speaking No, they are not the same. No doubt both have some similar factors but they are different from other aspects. You can’t use one for the other. They are different because lenses fit your eyes and glasses are placed at a distance from your eyes. That’s why lenses require more information about the width and curve of lens.
You can get many options while selecting glasses and lenses. There are many stylish frames you can buy according to your face. If you want to hide the secret that you have weak eyesight, contact lenses are the best option.
It is easy to wear eyeglasses as you can take off them anywhere you want. It is easy to carry them without any fear of damage. Contact lenses need more care as they are so delicate and sensitive.
Differences Between The Prescription Of Glasses And Contact Lens
Before getting your eyeglasses or contact lenses, it is important to be aware of their differences.
As you know, eyeglasses are easy to understand and very popular as many of us like to wear them. If we talk about contact lenses, it is complicated as their prescription has the power of vision according to near and farsight.
Contact lenses are difficult to wear and so delicate that you have to care for them properly.
The Contact description has many specific terms that are essential to understand. Let’s see them in detail:
Base Curve: This is the size of the lens that is also known as BC. You can know about actual BC in the shape of the cornea to fix it.
Diameter: The diameter or DIA is used to check the lens’s actual size and guides you to fix it properly. The normal range of DIA is between 13.5-14.5.
Brand Name: The brand name and many other specifications are mentioned in the product in detail. If you sleep while wearing a contact lens, don’t worry, each kind of lens has a fixed rate of oxygen breathability.
Expiry Date: Contact lenses have an expiration period that is mentioned on the prescription. Usually, it may expire after one or two years. After that, you have to get a new prescription from your doctor.
Let’s try to understand the difference with this table.
