Vision Over 40 · Presbyopia
Presbyopia / Old-sight / Reading difficulties:
‧Definition:
Presbyopia is a refractive error associated with aging of the eye that results in progressively losing ability to focus clearly on near objects.
‧Symptoms:
- usually start around 40 years old, there will be difficulties to focus near objects, such as mobiles and books.
- headache and eye strain associated to reading books and view digital devices.
- for some severe cases, stiff neck and neck pain will be caused.
‧Cause:
It is due to hardening of the lens inside the eye causing focus of light behind rather than on the retina when looking at close objects.
Mini screening for lag of accommodation:
If you see the text on green field sharper than that on red field, you may have presbyopia. You should consult optometrist for eye examination.
Management of Presbyopia:
1. Single vision reading glasses: only for near (close reading) vision
2. Bi-focal glasses: for distant and near vision
4. Multi-focal contact lenses for presbyopia.

Simply enjoy good vision again with your new progressive lenses
Progressive spectacle lenses are optical masterpieces which offer smooth vision from far to near. They help you look smart and young. But not all progressive lenses are the same. Your progressive lenses should meet your needs, lifestyle and budget. They should provide you with natural and comfortable vision. The fitting and dispensing of progressive lenses needs professional optometric service.
No two faces are equal. No two eyes, noses or ears are equal. Not even the right and left sides of our faces are symmetrical. If this individuality of your face is not taken into account in the production of a progressive lens, you may not be able to fully benefit from the optical performance of the lens. Up to 40% of valuable visual acuity can be lost.
By taking into account the facial profile of the wearer , e.g. how they look through the lens and how the frame sits on their nose and ears, the progressive lenses produced provide precisely the visual support needed. In our center, opticians can work precisely with state of the art equipment. The i.Terminal®2 from ZEISS provides an objective image of the spectacles wearer with the frames. We can measure the parameters needed for progressive lenses production precisely and objectively.
The benefits of precise progressive lenses fitting and personalized progressive design are:
-
natural vision
-
enhanced vision clarity
-
relieve eye strain

Presbyopia multifocal contact lenses:
Besides progressive spectacles, an alternative way to manage presbyopia (reading difficulties) is contact lens wear. We have different kinds of presbyopia contact lenses to meet your needs. Some options can correct astigmatism up to -6.00D, such as rigia gas permeable (RGP) lenses and hybrid lenses. We also fit soft multifocal contact lenses and nighttime contact lenses.
