<p>1. Single vision lens</p>
<p style="margin-left:0px; margin-right:0px">Single-vision prescription lenses are for people who need to correct one field of vision, either for distance, intermediate (computer), or near vision (reading). They contain the same amount of vision correction throughout the entire lens. There is no ADD in the prescription in the single vision prescription and there are no lens height requirements for single vision prescription.</p>
<p>2. <!--[endif]-->Bifocals</p>
<p>Bifocals (sometimes called “lined bifocals”) contain two prescriptions within the same lens and can correct both nearsight and farsight vision requirements. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision. The contrasting lense <span style="font-size:11.5000pt"><span style="font-family:Roboto-Regular">s</span></span>are separated by a noticeable line.</p>

<p>3. Progressives</p>
<p style="margin-left:0px; margin-right:0px">Progressives are multifocal lenses that contain at least three prescriptions. They have 3 main fields of vision, including near, intermediate, and distance. However, progressives do not have a visible line between prescriptions. This gives the wearer a seamless and uninterrupted transition when looking from up-close objects to far-away distance.</p>

<p style="margin-left:0px; margin-right:0px"> </p>
<p style="margin-left:0px; margin-right:0px">Advanced Progressive lens</p>
<p style="margin-left:0px; margin-right:0px">Advanced Progressive lenses are the most popular type of high definition lenses and are made by free form technology that can allow you to achieve better optics. The progressives are added on the backside of the lens to enlarge visual fields and minimize the uncomfortable effects. Comparing these with the standard progressive lens, Advanced Progressive lenses are easier to get used to.</p>

<p><!--[if !supportLists]-->4. <!--[endif]-->Computer lenses</p>
<p style="margin-left:0px; margin-right:0px">The lenses of computer glasses are designed to deal with eyestrain caused by prolonged hours staring at<span style="font-size:11.5000pt"><span style="font-family:Roboto-Regular"> </span></span>computer screens. Computer glasses help with an intermediate distance of around 20 to 26 inches, which is the distance most people sit from their monitor. Many computer glasses have light yellow/brown tinted lenses to block out blue light radiating from your electronic devices.</p>
<p style="margin-left:0px; margin-right:0px"> </p>
<p>5. <!--[endif]-->Reading glasses</p>
<p style="margin-left:0px; margin-right:0px">Reading glasses are made primarily for presbyopia which is an age-related eye disease most people experience around 35 to 45 years of age. Presbyopia is caused by a decreased elasticity in the eye's lens, making it more difficult to focus on objects in a close range.</p>
