After reading this article you will understand why you really, really must do a vision test with a professional optometrist before buying glasses
Multifocal glasses do only with an optometrist A specialist in
optometry is a paramedical profession and studied in institutions of higher learning for 4 years. In addition to academic studies the optometrist is required to do an internship, and then pass practical and theoretical licensing tests in order to obtain the certification.
The optometrist knows how to identify many visual impairments-diagnose them accurately and give solutions to a variety of problems such as myopia (long-term vision problems-TV, driving), hyperopia (short-term vision problems-such as reading),
astigmatism (difference in corneal curvature or lens blur. And lack of focus-cylinder). In addition the optometrist diagnoses problems of lazy eye, strabismus and weaves appropriate treatment.
Among the many solutions available to optometrists are multifocal lenses that are used for multi-focus vision. Multifocal lenses are custom lenses tailored to the customer's needs, specific vision problems and lifestyle.
Therefore, adjusting multifocal glasses should only be done by a professional optometrist who knows how to make a perfect fit of the lenses. An inaccurate solution can be harmful to the eye in the distant medium.
What is a multifocal?
A multifocal lens is a lens with several focal points, which provides an ideal optical solution for all vision ranges in one lens, thus reducing the need for additional pairs of glasses for different vision distances.
The lens simulates the natural vision of a person who does not need glasses and corrects the vision according to the prescription.
In addition, the lens prevents strain and fatigue of the eyes and headaches caused by the use of several separate pairs of glasses that are worn and removed intermittently.
Why do we need multifocal lenses?
Over the years, the body undergoes physiological changes that also affect the quality of vision
. This situation requires close-fitting glasses that focus the vision only on the distance to which they have been adjusted.
In situations where an optical solution is needed for several ranges and distances, such as office work with reading material and work in front of a computer, or in a situation where the client wears distance glasses but also needs reading glasses, there is a need to adjust a multifocal lens.
Most often, people will need multifocal ranging in age from 42-45, an age range in which blurring begins in the near vision range.
Multifocal lenses-tips for proper purchase:
1. It is very important to order the glasses only from a professional optometrist who is skilled in fitting multifocal lenses.
2. Check that the place where you purchase the eyeglasses has experience in multifocal adjustment and has the equipment to perform the test in the most thorough and accurate manner.
3. The exact vision needs of the optometrist who performs the test should be noted. Everyone needs correction in different directions and distances.
For example-a lecturer in the class will also want to look up and see the board closest to him and also look directly and see the students at the end of the class, while an accountant will need a wider reading and computer area and less distance .
4. Select the frame of the glasses before the vision test. The fit of the lenses in the frame may vary depending on the shape of the frame on your face.
5. It is very important to purchase advanced multifocal lenses that will allow for quick adjustment, that will allow easy transitions between the focal points and a wide field of view and of course that the lenses will be thin and aesthetic.
6. Measure the prepared glasses in the presence of the optometrist. It will guide you in the right use that suits your specific needs in each direction of view, and the adjustment to glasses will be easy and quick.
7. Not everyone adapts immediately to multifocal. Some people will have an adjustment time of several hours and some will require several weeks. In order for the adjustment to be faster, it is worthwhile to wear the glasses a lot in the first few days.
8. If a problem arises, it is important to return to the store and talk to the optometrist. Sometimes it is necessary to adjust the glasses on the face, to get another explanation about the correct use of glasses that significantly helps for quick adaptation and satisfaction from the lens.
9. Are you going to make your first multifocal glasses? It is recommended to make portfolio glasses, with the advanced SmartZoom lenses from Seiko Germany, which are designed exactly for those who make their first multifocal glasses, which allow for quick and comfortable adjustment from the very first moment.
