Pre-assembled glasses, when do you need to use them?
What are pre-assembled glasses? Also called reading glasses, they are a practical solution for anyone who needs vision correction for reading or for those who work on a computer. These optical devices are used for reading or for close-up viewing. They are already mounted with predefined lenses, having a standard graduation and available in a variety of diopters (lens power).
Unlike custom eyeglasses, which require a specific optical prescription, pre-assembled glasses can be purchased immediately and do not require a visit by an optician or ophthalmologist.
Pre-assembled glasses, on what occasions are they used?
Pre-mounted glasses are the ideal choice in some specific situations:
- Emergency or temporary lack of prescription glasses. If you have lost or damaged your eyeglasses andneed a temporary solution to see, pre-fitted glasses can be useful while waiting to have your glasses available again.
- Slight correction. If you suffer from mild nearsightedness or farsightedness and only need a little help to see up close or far, pre-fitted glasses may be sufficient.
- Occasional necessities. If you only need glasses in some specific situations, such as in a restaurant, pre-assembled glasses will certainly be the right choice.
- Limited budget. This type of glasses are less expensive than prescription glasses They are the cheapest possible choice for those on a budget, although not the best possible choice.
- Spare glasses. It’s helpful to have a spare pair of pre-fitted glasses, in case your prescription glasses suddenly break or get lost while you’re away from home or traveling.
What advantages do reading glasses offer?
The pre-mounted glasses offer the following Advantages:
- Convenience and immediate availability. One of the main advantages of pre-fitted glasses is comfort. They can be purchased in optical stores, pharmacies, supermarkets or online without the need to wait for a personalized prescription. This makes them ideal for those who need reading glasses in a short amount of time.
- Wide choice of styles. Pre-mounted glasses are available in a wide range of styles, shapes, and colors. This allows you to choose glasses that suit your personal taste and style, without having to compromise aesthetics. On the market we can also find pocket pre-assembled glasses.
- Cost-effectiveness. Pre-fitted glasses are more affordable than custom prescription glasses. This makes them a cost-effective choice for those who need vision correction for specific tasks such as reading or working on a computer.
- Ideal as reading glasses. Pre-fitted glasses are especially popular among people with presbyopia, a common condition linked to aging, which makes it difficult to focus on nearby objects. They can be used as reading glasses without the need for a specific prescription.
- They are spare glasses. Pre-fitted goggles can serve as spare or emergency goggles. They can be kept in your bag or car to deal with situations where you might need a sudden visual correction.
The limitations of pre-fitted glasses
Reading glasses, in addition to the advantages, also have limitations. Let’s see what they are.
- Lack of personalized accuracy. Pre-fitted glasses do not offer the accuracy of a personalised optical prescription. If you have complex vision correction or a significant difference between your eyes, you may need custom-made eyeglasses.
- Limited graduations. The range of diopter powers available in pre-mounted glasses may not suit everyone’s needs. In some cases, you may not find the exact graduation needed.
- Not suitable for continuous use. Pre-mounted glasses are ideal for specific tasks such as reading or working on a computer, but they may not be suitable for continuous use or more complex visual corrections.
Is an eye examination required before purchasing?
Around the age of 40, many people notice changes in vision. You may squint while reading or feel like your eyes can no longer focus as closely as they used to. Changes in vision are likely to be age-related, but blurry vision can also be a sign of a serious eye problem or disease.
Before purchasing a pair of pre-fitted glasses, it is recommended that you make an appointment with an ophthalmologist for a complete eye examination.
After your eye exam, you may find that you have presbyopia, a common age-related condition for which there is no good cure. This condition occurs when the lenses of the eyes lose elasticity. It can also happen that the muscle that supports the lens weakens.
Those with presbyopia have more difficulty focusing on nearby objects. For this reason, it is noticeable when reading or trying to pass the sewing thread through the eye of the needle.
