Decoding The Importance of Prescription Glasses:
Did you know that your eyes are composed of two million parts that move together to bring out a perfect vision? Considering the complexity, even minor damage would mean that your eyes won't be able to function the way they used to. At this point it is important to mention that an individual on an average spends around 6 hours and 40 minutes on the screen every day, this can be sitting on the laptop, watching television or mobile phones. With such huge bombardment of different kinds of radiation from different sources, the vision might get affected. To overcome this, one must go for regular eye-check-up before the problem aggravates. While visiting an eye-specialist, you might have come across the term prescription glasses. These are the number of glasses which are recommended for vision correction. Though great vision does not have an important role to play, accurate visions helping in managing essential day-to-day activities such as sending messages or emails, road signs, driving safely and reading the menu when you are out to have a good time with friends or family.
If you are not sure whether you must choose prescription glasses or not, then there are a few questions that you must ask yourself:
- Are facing continuous headaches?
- Are you squinting while trying to focus on the objects?
- The glasses that you are wearing are scratched?
- Have you increased the font size on your phone or computer?
- Do you get easily bothered by bright sunlight or too much glaring?
- Are you unable to read small prints, like labels present at the back of products?
- Do you experience hazy vision, ghosting or double images?
When the answer to at least three questions is an outright yes, then you need to seek the help of a certified professional for getting the right glasses.
Commonly Asked Questions About Prescription Glasses
Now, when it comes to getting prescription glasses you may have several questions in your mind, some of them include:
1. What do the different abbreviations or numbers present in prescription mean?
After a detailed eye examination, the optometrist would write down a prescription for the ideal glasses. In this prescription, you may find a few abbreviations such as OD, ADD, OU and more. Each has an integral meaning, for example
- OD means Oculus Dexter (right eye)
- OU means oculus sinister (left eye)
- ADD stands for additional power measurement for the multifocal and bifocal lens of the prescription glasses.
For each eye, the doctor also mentions a number along with a positive (+) or a negative (-) sign. The positive sign indicates that you are farsighted and the negative is for the opposite i.e. near-sighted.
2. Are prescription contact lenses the same as the prescription for glasses?
A common misconception that most of the people have is prescription for glasses is same as that for contact lenses. Well, that's never the case. You need to know that the glasses will be at a distance of at least 12mm from your eyes, while the contact lenses would be placed directly onto the eyes. Both the prescriptions demand correctness of both near-sightedness and farsightedness. In case you want to wear both prescribed glasses and contact lenses occasionally then the good practice would be to ask for a prescription for contact lenses separately.
3. How often must you check your eyes when you wear prescription glasses?
The prescription does change, so it's crucial to get your eye examined regularly. Those who are aged between 19 to 40 years should get their eyes checked once in every 2 years, while people who are older than 40 must examine their eyes once in a year.
Make sure that you contact a good optometrist for prescription glasses, they will help you with vision correction and at the same time are helpful in case someone has undergone eye surgery.
