Types Of Lenses For Glasses. When you first realise that you need a pair of glasses to correct your vision the choices can be overwhelming. Nothing is better than our opticians in Hartshead advice but we will try to simplify the choices of lenses for your glasses. That is unless you decide to go down the contact lenses route.
Single Vision Lenses
Single vision lenses are the basic and usually are the least expensive lenses there are. Made to correct one defect in your vision, long sighted or short sighted. If you just have 1 of the 2 conditions o will be prescribed single vision lenses.
These are for when you have multiple vision issues, some lenses can also be trifocal. The bifocal lens caters for people who have problems with short sightedness and long sightedness. If you also have intermediate vision problems then you will more than likely prescribed the trifocal lenses. Also referred two as varifocal lenses.
They are the basic eye correction lenses but then their are a few more choices to make about your lenses.
Progressive lenses perform the same job as bifocals and trifocals, but in a different way. They work around the dividing lines of bifocals. This was a known inconvenience glasses wearers dealt with for many years. There is a downside of removing the dividing line between the lenses, the actual field of vision is smaller than on the regular bifocals and trifocals.
Screen Or Computer Glasses
One of the newest types of lenses on the market, not strictly prescription glasses. We have listed them because digital eye strain is becoming a more common condition. If you’re one of the millions of people who spend long hours in front of the computer, chances are you’ve probably experienced eye strain. Digital eye strain (also known as computer vision syndrome) occurs when your eyes become “tired” from staring at digital devices for an extended period of time.
Monitors emit blue light, certain ranges of which are harmful to our eyes. Computer glasses filter out this blue light, minimising general eye strain and fatigue, reducing headaches, and generally keeping your eyes healthier. If your job involves a lot of screen time, speak with our opticians in the Liversedge area.
Photochromic Transition Lenses
Transition lenses (Photochromic lenses) darken when they are exposed to UV rays (sunshine). This eliminates the need to have a second pair of sunglasses, this is a popular choice for keep the cost of glasses down. They are not strictly prescription so check with our opticians at Low Moor to see if they are covered. It may add additional cost to the glasses but then you only have to get one pair.
It’s worth noting that the transition lenses will also darken on cloudy days as well, some people are surprise they do, others actually find it annoying. So after your have been prescribed your glasses, single vision, progressive, or varifocal the photochromic is an enhancement to the basic lens. Photochromic lenses can come in different colours which have added benefits.
Now if you lead a busy active lifestyle then these lenses may the ones that you need. Polycarbonate lenses are tough and durable, ideal for sports lovers and great for clumsy kids as well.
Aspheric lenses are made up of differing degrees of curvature over its surface. Thus allowing the lens to be thinner and flatter than other lenses. The benefit of these lenses result in a much wider field of vision on the actual lens themselves.
The trivet lenses are ver similar to the polycarbonate lenses, however, they are made from a newer plastic. They are lightweight, thin, and impact-resistant and may result in better vision correction than the polycarbonate attentive.
High index plastic lenses
These are for people who require a strong prescription lens. Normally the lens would be very thick to correct this vision impairment, the high index plastic allows the lens to be thinner, lighter and flatter. Which in turn makes them more fashion friendly than they used to be.
