Proper usage of regular and multifocal reading glasses
Be careful of ready-made reading glasses
The buying of over-the-counter reading glasses requires several tips, since there are possibly flaws and distortions. These glasses are ready-made so that they are more likely to be unsuitable for some people than prescription lenses from eye doctors. In fact, reading glasses can not provide good distance vision. Even with over-the-counter reading glasses, regular eye exams should not be skipped. Eye exams are effective not only in diagnosing visual refractive errors and presbyopia, but also in detecting signs of an underlying eye disease. For presbyopic patients, the most advisable practice is to buy customized reading glasses from an eye care practitioner and get regular eye examinations.
Position progressive glasses properly to get great help
Progressive addition lenses are great for all distances. With a soft design, these lenses provide acceptable and comfortable vision. Some eye doctors also think that progressive lenses offer much more natural and usable vision than bifocals and trifocals. Unlike bifocals and trifocals, progressive lenses have as many as nearly 20 focal points. There are many notable brands available such as Zeiss. Incorrectly positioned progressive lenses can cause blurry vision. Plastic markers can be used to check the right positioning of progressive lenses, both side to side and up and down.
Do not mix bifocals with trifocals
Bifocal lenses are designed to focus at two distances and trifocals are made to help at three distances. Some people may wonder that these two types can be interchangeably used. This is an improper way. Bifocal lenses may cause problems if their lines have not been properly fitted. For example, the line may be in the middle of the vision even if the wearer looks straight ahead. These two types require different fittings. Bifocals have only one vision division on the lens, while trifocals have two. Both of the division lines should be placed in exactly proper ways. In fact, bifocals can not provide appropriate computer vision as trifocals do. From another perspective, it is needless to use trifocals if no computer work is involved.
Golfers need occupational multifocal glasses
For golfers, using bifocal eyeglasses may meet a dilemma that these people need to both read the score card and swing. Neither bifocal lenses nor progressive lenses can offer satisfying vision for both of the two activities. In this case, more than one pair of glasses is needed. Another option for golfers is to use occupational multifocal glasses. Such an occupational pair for golfers can be achieved by putting a round-top bifocal section in the outside corner of one of the lenses. Compared with the solution requiring several pairs, the second solution is certainly more convenient.
