Reduce your eyestrain from PCs or smart phones

No eyestrain
Designed for eye relaxation

From the lens center to the peripheral area the lens power is gradually reduced.
This concentric progressive design works well for your distant, intermediate and near view.


● UV protection <UV cut rate>

● High oxygen permeability

Suitable for "EX-UV PAL"


・GP lens user
・Usually using PCs or smart phones
・Usually reading books
・Sometimes feel eyestrain

When you see something close by or read small letters, ciliary muscles in your eye are tensed to focus on them.
If such condition has been prolonged, it may cause "eyestrain".
Nichicon EX-UV PAL is the special progressive lens designed to reduce your eyestrain.

Diquas TM, The new eye solution for dry eye syndrome

Dry eye syndrome is known as the decreased tear secretion resulting in various vexing conditions.
The curent treatment is the recurrent use of artificial tear solutions. However tear film consists of three different layers, mucin, aqueous, and lipid, artificial tear slutions only help cover the decreased aqueous layer. In the treatment of dry eye syndrome, the other two layers are also expected to be eked out. The mucin layer plays a important role to lubricate the ocular surface anchoring the aqueous layer to the cornea. Without sufficient mucin layer, the tear evaporation from ocular surface cannot be prevented however recurrently artificial tear solutions might be used. In addition, the mucin layer froms the surface bufler to cornea, and the decreased mucin layer might cause corneal bacterial infection.
Diquas TM, newly developed by Santen Pharmaceutical Co.Ltd is the first eye solution in the world to stimulate mucin secretion, so the combined use of Diquas TM and artifical tear solutions will show the high potentials in the treatment of dry eye syndrome.

Robotic tele-surgery

Three dimensional TV are now widely on sale and some of the viewers could have enjoyed stereoscopic scenes of the soccer world cup games.
This sophisticated technology plays an important role not only in the entertainment buisiness but also in the medical industry. Let me explain how this technology is combined with robotic technology to enable the so-called robotic tele-surgery.
When a patient requires an immediate and difficult operation, the operation can be done by this new technology. The patient images taken by the 3-D camera are transmitted to the surgeon sitting before 2robotic arms in which the movements are duplicated by the robotic arms near the patient.
The surgeon maneuvers the robotic arms into the 3-D image of the patient's lesion , cuts,exterpates and stiching are performed by the other robotic arms before the patient.
In this way, this new technology will bring a great boon to the patients living in a remote place where the latest medical services are not easy to access. This technology requires us surgeons to have not only good vision in both eyes but also good binocular vision so that we can perform exact surgical procedures on 3-D images of patients.

Pikachuu in your computer

Pikachuu,one of the characters from the Japanese smashing hit anime, Pocket Monster, is well known all over the world. Pikachuu has a stunning and powerful weapon; lightning from its tail. But its lighting is so bright and rapidly frickering that children watching the anime on TV sometimes have dizziness, or in the worst case, an epileptic fit. But you cannot blame Pikachuu alone for it because you might be put under the same condition with the anime viewing children when you are working on computers. Because of the high speed CPU, when you touch the panel or computer mouse, the computer images rapidly change, resulting in the sudden change of screen illumination. After the spending long hours on a computer, you might suffer the same flickering eye strain as the children. To avoid this eye strain, you should work under a bright room light and keep some distance from your computer screen.
If not, you might have a sudden Pikachuu attack unconsciously during your computer work.

The orbital Puffiness

Almost a decade ago, the female duo named "Puffy" got a big break in the Japanese pop music world. Slovenly dressed with T-shirts and jean pants, their singing style is lackdaisical. Because of their group name, when I see them on TV they always remind me of a patient I had at my clinic.
It was 5-year old boy with severe palpebral lid and the mother told me that the previous doctor prescribed him an anti-allergic eye solution. Of course a skin allergic reaction causes edema but it should be accompanied with inflammatory change.
In case of systemic edema caused by acute nephritis or cardiac failure, there is no sign of inflammation, however edema is more noticeable in orbital area because palpebral tissue contains gaps to enable rapid lid movement.Together with other physical findings, I diagnosed this boy with acute nephritis and transferred him to the chilren's hospital immediately.
Later I received a letter from the pediatrician saying the boy was seriously ill from nephritis and admitted to the hospital. One and a half years later, the boy showed up again with the mother and I was very happy to know that they dropped in just to say thanks to me this time.
