Computer reading glasses are basically special spectacles that help in reducing the eyestrain that is caused due to staring at the computer monitor. However, care must be taken while buying them because many unscrupulous vendors sell cheap tinted glasses as computer reading glasses. Hence, check out a reputable source to get your computer glasses.
These days you get modern and lightweight rimless computer reading glasses that are made of highly flexible stainless steel. While there are bifocals available, but for those who do not wear spectacles there are computer glasses which have a slight correction of +0.25 to +0.75, which helps to reduce the focal point just enough so as to bring about relief on the strain caused to the eye muscle. Plus, they have an anti-reflective coating, which helps to reduce the glare while it also imparts a slight amount of tint. However, if you do require reading glasses, there are single vision lenses that are low powered, which you could check out.
Design Factors for Computer Reading Glasses
While the design of one’s computer reading glasses is an individual matter, and there are lots of varieties to choose from, experts recommend the rimless, low powered glasses with frames that are ultra light, along with choosing lenses according to the requirement of each eye. If you do use reading glasses, then you will discover that while you use the computer you will require a lower power. The computer glasses that have the +0.25 to +0.75 correction, as has been mentioned above, are of the lowest power, which is ideal for the 22-inch to 30-inch distance that usually exists between the user and the computer. Most lenses of computer reading glasses have an anti-reflective coating on them. The best solution of course is to get a pair of computer reading glasses according to your exact prescription requirements as well as the conditions in your workplace.
The Anti-Glare Coating on Computer Reading Glasses
While the anti-glare coating does result in having to clean the glasses more frequently, however, it also improves its resistance to scratching.
The term ‘glare’ when associated with using the computer actually means the intensity of the surrounding light that is higher than that of the computer, which causes visual noise and affects the ability of the eyes to focus properly on the monitor. Computer reading glasses that have anti-glare coating on their lenses alleviates that by reducing the visual noise.
Computer Reading Glasses with Tinted Lenses
Tinted lenses are supposed to reduce too much of the blue light spectrum. Since there are no reliable scientific studies that prove this presupposition, and since just about any tint in the lenses will have the effect of cutting down on the intensity of the light and cause the pupils to dilate, leading to a depth of field that is narrower, experts generally do not recommend tint on the lenses of computer reading glasses.
Can Reading Glasses be Used as Computer Glasses?
Regular reading glasses are generally not suitable while using the computer, since the interpupillary distance can be quite great, which causes even more eyestrain and also induces prism vision.
The best way to counter that is to get computer reading glasses with suitable lenses according to the requirement of each eye as well as choosing the correct nose bridge so that the interpupillary distance can be adjusted appropriately.
Computer Reading Glasses with Progressive Lenses
Progressive lenses are usually prescribed for computer reading glasses. Then are generally more expensive compared to normal lenses, plus they need to be made very carefully, according to the exact prescription. These eyeglasses also need a period of adjustment for the user to get completely comfortable with them. They are usually not appropriate for made-to-wear computer glasses.
