II. Lens Options :

• Selecting the correct lens here is now made easy

(a) Single Vision

---Glass NO CHARGE

• Single Vision means either for distance or for reading. If you need both corrected in one pair of glasses then look at bifocals or varifocals.
• We will fit single vision glass lenses into the frame of your choice for distance or reading at no extra charge.
• Not recommended for children under the age of 15 years for safety purposes.
• Advantages and disadvantages of glass.

---Glass over +/-4.00DS

• If the spherical part [(3) above] shows a number over + 4.00 or less than - 4.00, then you have choose this option. We need to make the lens specially because it goes beyond the normal stock lenses

---Plastic CR39

• CR39 is the world-wide standard for plastic lenses. It's a high-grade material suitable for any prescription. Today 90% of all prescriptions are fitted in plastic.
• Advantages and disadvantages of plastic.

---Plastic over +/-4.00DS

• If the spherical part [(3) above] shows a number over + 4.00 or less than - 4.00, then you have choose this option. We need to make the lens specially because it goes beyond the normal stock lenses

---Photochromatic glass brown / grey

• These lenses have a special material (pigment) that makes them go dark in the sun so they act as prescription sunglasses.
• Select between brown or grey.
• I suggest to my patient to select the color that best matches the frame.
• In doors and at night, the lenses are almost completely clear.
• Advantages and disadvantages of glass.
• Advantages and disadvantages of Photochromatic lenses.

---Photochromatic transitions plastic

• Comes in a brown tint.
• Advantages and disadvantages of plastic.
• Advantages and disadvantages of Photochromatic lenses.

(b) Bifocals

• One lens corrects both distance and reading.
• With this type of lens you can see the shape of the reading segment (reading part of the lens).
• It's always best to select the same lens type that you've had before, unless otherwise advised by your eyecare professional.
• Let me describe the different types

---D-seg Flat Top 28mm

• The D-seg is the reading bit you can see on the above lens.
• It isn't stuck onto the lens, or separate in any way, but you can still see it.
• The standard size is 28mm.
• This type is the most popular of all the bifocals.
• Advantages and disadvantages of glass.
• Advantages and disadvantages of plastic.
• Advantages and disadvantages of Photochromatic lenses.

---Round-seg

• Not as popular as the D-seg.
• The round shape allows a "smoother" change from distance to near.
• Slightly less field of view than the D-seg.
• Available only in glass or plastic.
• Advantages and disadvantages of glass.
• Advantages and disadvantages of plastic.

---Plastic A-seg Ultex

• This segment is cut out from a large circle. It gives more reading area in the corners.
• Available in light-weight clear plastic only.
• This bifocal is rarely prescribed today.

---Executive

• This segment is suitable for certain occupations such as secretarial, architects and for certain trades e.g. plumbers, mechanics who are in awkward places. It gives them more room to look at the job up close.
• Available in glass, plastic and photochromatic grey only.
• Advantages and disadvantages of glass.
• Advantages and disadvantages of plastic.
• Advantages and disadvantages of Photochromatic lenses.

(c) Varifocals

• By far the most popular lens today (85%) for correcting distance and near vision.
• There is no line visible on the lens.
• The prescription changes gradually from distance to near, so there is no "jump" as with the bifocals.
• No one can tell you are wearing lenses for distance and near. Cosmetically they are far more attractive.

• The correction is nice and smooth and graduated.
• Available in glass, plastic, and photochromatic.
• Advantages and disadvantages of glass.
• Advantages and disadvantages of plastic.
• Advantages and disadvantages of Photochromatic lenses.

• Lenses are made using different densities. When a material is more dense, it means it has a higher index.
• Hi-index lenses are made so the lenses are thinner for higher powers.
• I recommend Hi-Index option for thinner lighter lenses especially when the sphere (2) section of your prescription is higher than + 3.50 or lower than - 3.50.
• Hi-Index lenses look better, are thinner and lighter.

IV. Anti - Scratch

• This is a coating that goes onto plastic lenses for protection against those light scratches that tend to happen over time.
• This is a helpful coating meant to increase the life of the lens.
• Note if your lenses are glass, you don't need to select this option because Anti - Scratch coatings are only for plastic lenses.

V. Tinting Options

• These are coatings that help reduce the amount of light entering the eye. The most popular colors are Brown and Grey and I recommend you select the appropriate color here to match your frame. Yellow usually is used for sharp shooting and other sports while other colors can be used for cosmetic purposes.
• Of course, please email me if you would like a color not listed here.
• Please note that only brown and grey tints are available for glass lenses. If you require any other tint you will need to select a plastic lens.

       Light                  Medium               Dark

Graduated Brown

Graduated Grey

Full Green

VI Ultra-Violet (UV) Protection :

• I advise this coating for everyone especially children.
• A must for sunny and bright climates.
• Also if you are using a monitor for many hours.

VII Anti-Reflection (AR) Coating :

• If your prescription is over -3.00 then an AR coating will reduce unwanted reflections bouncing off the front and back surfaces of your lenses. So I definitely recommend it for these prescriptions.
• Also recommended for safer and more comfortable night driving.
